WAFV2

Table of Contents

Client

class WAFV2.Client

A low-level client representing AWS WAFV2:

import boto3

client = boto3.client('wafv2')

These are the available methods:

associate_web_acl(**kwargs)

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Associates a Web ACL with a regional application resource, to protect the resource. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

For AWS CloudFront, you can associate the Web ACL by providing the Id of the WebACL to the CloudFront API call UpdateDistribution . For information, see UpdateDistribution .

Request Syntax

response = client.associate_web_acl(
    WebACLArn='string',
    ResourceArn='string'
)
Parameters
  • WebACLArn (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the Web ACL that you want to associate with the resource.

  • ResourceArn (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the resource to associate with the web ACL.

    The ARN must be in one of the following formats:

    • For a CloudFront distribution: ``arn:aws:cloudfront::account-id :distribution/distribution-id ``
    • For an Application Load Balancer: ``arn:aws:elasticloadbalancing: region :account-id :loadbalancer/app/load-balancer-name /load-balancer-id ``
    • For an Amazon API Gateway stage: ``arn:aws:apigateway:region ::/restapis/api-id /stages/stage-name ``
Return type

dict

Returns

Response Syntax

{}

Response Structure

  • (dict) --

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
check_capacity(**kwargs)

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Returns the web ACL capacity unit (WCU) requirements for a specified scope and set of rules. You can use this to check the capacity requirements for the rules you want to use in a RuleGroup or WebACL .

AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

Parameters
  • Scope (string) --

    [REQUIRED]

    Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

    To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

    • CLI - Specify the region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
    • API and SDKs - For all calls, use the Region endpoint us-east-1.
  • Rules (list) --

    [REQUIRED]

    An array of Rule that you're configuring to use in a rule group or web ACL.

    • (dict) --

      Note

      This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

      A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

      • Name (string) -- [REQUIRED]

        A friendly name of the rule. You can't change the name of a Rule after you create it.

      • Priority (integer) -- [REQUIRED]

        If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

      • Statement (dict) -- [REQUIRED]

        The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

        • ByteMatchStatement (dict) --

          A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

          • SearchString (bytes) -- [REQUIRED]

            A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

            Valid values depend on the areas that you specify for inspection in FieldToMatch :

            • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
            • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

            If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

        • SqliMatchStatement (dict) --

          Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

                Specify NONE if you don't want any text transformations.

        • SizeConstraintStatement (dict) --

          A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

          If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

          If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

        • GeoMatchStatement (dict) --

          A rule statement used to identify web requests based on country of origin.

          • CountryCodes (list) --

            An array of two-character country codes, for example, [ "US", "CN" ] , from the alpha-2 country ISO codes of the ISO 3166 international standard.

            • (string) --
        • RuleGroupReferenceStatement (dict) --

          A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

          You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the entity.

          • ExcludedRules (list) --

            The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

        • IPSetReferenceStatement (dict) --

          A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

          Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the IPSet that this statement references.

        • RegexPatternSetReferenceStatement (dict) --

          A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

          Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • RateBasedStatement (dict) --

          A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

          When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

          You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

          • An IP match statement with an IP set that specified the address 192.0.2.44.
          • A string match statement that searches in the User-Agent header for the string BadBot.

          In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

          You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • Limit (integer) -- [REQUIRED]

            The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

          • AggregateKeyType (string) -- [REQUIRED]

            Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

          • ScopeDownStatement (dict) --

            An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

        • AndStatement (dict) --

          A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

          • Statements (list) -- [REQUIRED]

            The statements to combine with AND logic. You can use any statements that can be nested.

      A single regular expression. This is used in a RegexPatternSet .

      • RegexString (string) --

        The string representing the regular expression.

  • Tags (list) --

    An array of key:value pairs to associate with the resource.

    • (dict) --

      A collection of key:value pairs associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

      • Key (string) -- [REQUIRED]

        Part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

      • Value (string) -- [REQUIRED]

        Part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

Response Structure

  • (dict) --

    • Summary (dict) --

      High-level information about a RegexPatternSet , returned by operations like create and list. This provides information like the ID, that you can use to retrieve and manage a RegexPatternSet , and the ARN, that you provide to the RegexPatternSetReferenceStatement to use the pattern set in a Rule .

      • Name (string) --

        A friendly name of the data type instance. You cannot change the name after you create the instance.

      • Id (string) --

        A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

      • Description (string) --

        A friendly description of the set. You cannot change the description of a set after you create it.

      • LockToken (string) --

        A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

      • ARN (string) --

        The Amazon Resource Name (ARN) of the entity.

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Creates a RuleGroup per the specifications provided.

A rule group defines a collection of rules to inspect and control web requests that you can use in a WebACL . When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

    [REQUIRED]

    The web ACL capacity units (WCUs) required for this rule group.

    When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity .

    AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

  • Description (string) -- A friendly description of the rule group. You cannot change the description of a rule group after you create it.
  • Rules (list) --

    The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

    • (dict) --

      Note

      This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

      A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

      • Name (string) -- [REQUIRED]

        A friendly name of the rule. You can't change the name of a Rule after you create it.

      • Priority (integer) -- [REQUIRED]

        If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

      • Statement (dict) -- [REQUIRED]

        The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

        • ByteMatchStatement (dict) --

          A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

          • SearchString (bytes) -- [REQUIRED]

            A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

            Valid values depend on the areas that you specify for inspection in FieldToMatch :

            • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
            • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

            If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

          • PositionalConstraint (string) -- [REQUIRED]

            The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

            CONTAINS

            The specified part of the web request must include the value of SearchString , but the location doesn't matter.

            CONTAINS_WORD

            The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

            • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
            • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .

            The value of the specified part of the web request must exactly match the value of SearchString .

            STARTS_WITH

            The value of SearchString must appear at the beginning of the specified part of the web request.

            ENDS_WITH

            The value of SearchString must appear at the end of the specified part of the web request.

        • SqliMatchStatement (dict) --

          Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • SizeConstraintStatement (dict) --

          A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

          If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

          If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

        • IPSetReferenceStatement (dict) --

                NONE

                Specify NONE if you don't want any text transformations.

        • RateBasedStatement (dict) --

          A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

          When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

          You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

          • An IP match statement with an IP set that specified the address 192.0.2.44.
          • A string match statement that searches in the User-Agent header for the string BadBot.

          In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

          You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • Limit (integer) -- [REQUIRED]

            The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

          • AggregateKeyType (string) -- [REQUIRED]

            Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

          • ScopeDownStatement (dict) --

            An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

        • AndStatement (dict) --

          A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

Response Structure

  • (dict) --

    • Summary (dict) --

      High-level information about a RuleGroup , returned by operations like create and list. This provides information like the ID, that you can use to retrieve and manage a RuleGroup , and the ARN, that you provide to the RuleGroupReferenceStatement to use the rule group in a Rule .

      • Name (string) --

        A friendly name of the data type instance. You cannot change the name after you create the instance.

      • Id (string) --

        A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

      • Description (string) --

        A friendly description of the rule group. You cannot change the description of a rule group after you create it.

      • LockToken (string) --

        A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

      • ARN (string) --

        The Amazon Resource Name (ARN) of the entity.

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Creates a WebACL per the specifications provided.

A Web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the Web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a Web ACL can be a combination of the types Rule , RuleGroup , and managed rule group. You can associate a Web ACL with one or more AWS resources to protect. The resources can be Amazon CloudFront, an Amazon API Gateway API, or an Application Load Balancer.

Parameters
  • Name (string) --

    [REQUIRED]

    A friendly name of the Web ACL. You cannot change the name of a Web ACL after you create it.

  • Scope (string) --

    [REQUIRED]

    Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

    To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

    • CLI - Specify the region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
    • API and SDKs - For all calls, use the Region endpoint us-east-1.
  • DefaultAction (dict) --

    [REQUIRED]

    The action to perform if none of the Rules contained in the WebACL match.

    • Block (dict) --

      Specifies that AWS WAF should block requests by default.

    • Allow (dict) --

      Specifies that AWS WAF should allow requests by default.

  • Description (string) -- A friendly description of the Web ACL. You cannot change the description of a Web ACL after you create it.
  • Rules (list) --

    The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

    • (dict) --

      Note

      This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

      A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

      • Name (string) -- [REQUIRED]

        A friendly name of the rule. You can't change the name of a Rule after you create it.

      • Priority (integer) -- [REQUIRED]

        If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

      • Statement (dict) -- [REQUIRED]

        The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

        • ByteMatchStatement (dict) --

          A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

          • SearchString (bytes) -- [REQUIRED]

            A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

            Valid values depend on the areas that you specify for inspection in FieldToMatch :

            • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
            • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

            If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            CONTAINS_WORD

            The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

            • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
            • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
            EXACTLY

            The value of the specified part of the web request must exactly match the value of SearchString .

            STARTS_WITH

            The value of SearchString must appear at the beginning of the specified part of the web request.

            ENDS_WITH

            The value of SearchString must appear at the end of the specified part of the web request.

        • SqliMatchStatement (dict) --

          Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

        • SizeConstraintStatement (dict) --

          A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

          If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

          If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • GeoMatchStatement (dict) --

          A rule statement used to identify web requests based on country of origin.

          • CountryCodes (list) --

            An array of two-character country codes, for example, [ "US", "CN" ] , from the alpha-2 country ISO codes of the ISO 3166 international standard.

            • (string) --
        • RuleGroupReferenceStatement (dict) --

          A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

          You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the entity.

          • ExcludedRules (list) --

            The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

        • IPSetReferenceStatement (dict) --

          A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

          Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the IPSet that this statement references.

        • RegexPatternSetReferenceStatement (dict) --

          A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

          Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • RateBasedStatement (dict) --

          A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

          When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

          You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

          • An IP match statement with an IP set that specified the address 192.0.2.44.
          • A string match statement that searches in the User-Agent header for the string BadBot.

          In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

          You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • Limit (integer) -- [REQUIRED]

            The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

          • AggregateKeyType (string) -- [REQUIRED]

            Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

          • ScopeDownStatement (dict) --

            An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

        • AndStatement (dict) --

          A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

          • Statements (list) -- [REQUIRED]

            Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.

      • Id (string) --

        A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

      • ARN (string) --

        The Amazon Resource Name (ARN) of the entity.

      • Description (string) --

        A friendly description of the set. You cannot change the description of a set after you create it.

          A single regular expression. This is used in a RegexPatternSet .

          • RegexString (string) --

            The string representing the regular expression.

    • LockToken (string) --

      A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

Response Structure

  • (dict) --

    • RuleGroup (dict) --

      • Name (string) --

        A friendly name of the rule group. You cannot change the name of a rule group after you create it.

      • Id (string) --

        A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

      • Capacity (integer) --

        The web ACL capacity units (WCUs) required for this rule group.

        When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity .

        AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

      • ARN (string) --

        The Amazon Resource Name (ARN) of the entity.

      • Description (string) --

        A friendly description of the rule group. You cannot change the description of a rule group after you create it.

      • Rules (list) --

        The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

        • (dict) --

          Note

          This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

          A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

          • Name (string) --

            A friendly name of the rule. You can't change the name of a Rule after you create it.

          • Priority (integer) --

            If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

          • Statement (dict) --

            The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

            • ByteMatchStatement (dict) --

              A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

              • SearchString (bytes) --

                A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

                Valid values depend on the areas that you specify for inspection in FieldToMatch :

                • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
                • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

                If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

                If you're using the AWS WAF API

                Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

                For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

                If you're using the AWS CLI or one of the AWS SDKs

                The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160

                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >

                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

              • PositionalConstraint (string) --

                The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

                The specified part of the web request must include the value of SearchString , but the location doesn't matter.

                CONTAINS_WORD

                The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

                • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
                • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .

                EXACTLY

                The value of the specified part of the web request must exactly match the value of SearchString .

                STARTS_WITH

                The value of SearchString must appear at the beginning of the specified part of the web request.

                ENDS_WITH

                The value of SearchString must appear at the end of the specified part of the web request.

            • SqliMatchStatement (dict) --

              Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

              A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

              If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

              If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • ComparisonOperator (string) --

                The operator to use to compare the request part to the size setting.

              • Size (integer) --

                The size, in byte, to compare to the request part, after any transformations.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160

                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >
                    • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • GeoMatchStatement (dict) --

              A rule statement used to identify web requests based on country of origin.

              • CountryCodes (list) --

                An array of two-character country codes, for example, [ "US", "CN" ] , from the alpha-2 country ISO codes of the ISO 3166 international standard.

                • (string) --
            • RuleGroupReferenceStatement (dict) --

              A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

              You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the entity.

              • ExcludedRules (list) --

                The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

                  • Name (string) --

                    The name of the rule to exclude.

            • IPSetReferenceStatement (dict) --

              A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

              Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the IPSet that this statement references.

            • RegexPatternSetReferenceStatement (dict) --

              A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

              Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

              • FieldToMatch (dict) --

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10

                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • RateBasedStatement (dict) --

              A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

              When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

              You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

              • An IP match statement with an IP set that specified the address 192.0.2.44.
              • A string match statement that searches in the User-Agent header for the string BadBot.

              In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

              You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • Limit (integer) --

                The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

              • AggregateKeyType (string) --

                Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

              • ScopeDownStatement (dict) --

                An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

            • AndStatement (dict) --

              A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

              • Statements (list) --

              • ExcludedRules (list) --

                The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

    • LockToken (string) --

      A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

get_sampled_requests(**kwargs)

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Gets detailed information about a specified number of requests--a sample--that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.

GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

        A friendly name of the Web ACL. You cannot change the name of a Web ACL after you create it.

      • Id (string) --

        A unique identifier for the WebACL . This ID is returned in the responses to create and list commands. You use this ID to do things like get, update, and delete a WebACL .

      • ARN (string) --

        The Amazon Resource Name (ARN) of the Web ACL that you want to associate with the resource.

      • DefaultAction (dict) --

        The action to perform if none of the Rules contained in the WebACL match.

        • Block (dict) --

          Specifies that AWS WAF should block requests by default.

        • Allow (dict) --

          Specifies that AWS WAF should allow requests by default.

      • Description (string) --

        A friendly description of the Web ACL. You cannot change the description of a Web ACL after you create it.

      • Rules (list) --

        The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

        • (dict) --

          Note

          This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

          A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

          • Name (string) --

            A friendly name of the rule. You can't change the name of a Rule after you create it.

          • Priority (integer) --

            If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

          • Statement (dict) --

            The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

            • ByteMatchStatement (dict) --

              A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

              • SearchString (bytes) --

                A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

                Valid values depend on the areas that you specify for inspection in FieldToMatch :

                • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
                • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

                If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

                If you're using the AWS WAF API

                Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

                For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

                If you're using the AWS CLI or one of the AWS SDKs

                The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160

                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >
                    • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

              • PositionalConstraint (string) --

                The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

                CONTAINS

                The specified part of the web request must include the value of SearchString , but the location doesn't matter.

                CONTAINS_WORD

                The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

                • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
                • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .

                EXACTLY

                The value of the specified part of the web request must exactly match the value of SearchString .

                STARTS_WITH

                The value of SearchString must appear at the beginning of the specified part of the web request.

                ENDS_WITH

                The value of SearchString must appear at the end of the specified part of the web request.

            • SqliMatchStatement (dict) --

              Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160

                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol

                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • XssMatchStatement (dict) --

              A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.

              • FieldToMatch (dict) --

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                    NONE

                    Specify NONE if you don't want any text transformations.

            • SizeConstraintStatement (dict) --

              A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

              If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

              If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • RuleGroupReferenceStatement (dict) --

              A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

              You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the entity.

              • ExcludedRules (list) --

                The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

                  • Name (string) --

                    The name of the rule to exclude.

            • IPSetReferenceStatement (dict) --

              A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

              Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the IPSet that this statement references.

            • RegexPatternSetReferenceStatement (dict) --

              A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

              Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160

                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >
                    • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • RateBasedStatement (dict) --

              A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

              When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

              You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

              • An IP match statement with an IP set that specified the address 192.0.2.44.
              • A string match statement that searches in the User-Agent header for the string BadBot.

              In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

              You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • Limit (integer) --

                The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

              • AggregateKeyType (string) --

                Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

              • ScopeDownStatement (dict) --

                An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

            • AndStatement (dict) --

              A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

              • Statements (list) --

                The statements to combine with AND logic. You can use any statements that can be nested.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.

            • OrStatement (dict) --

              A logical rule statement used to combine other rule statements with OR logic. You provide more than one Statement within the OrStatement .

              • Statements (list) --

                The statements to combine with OR logic. You can use any statements that can be nested.

                • (dict) --

            • NotStatement (dict) --

              A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .

              • Statement (dict) --

                The statement to negate. You can use any statement that can be nested.

            • ManagedRuleGroupStatement (dict) --

              A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .

              You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • VendorName (string) --

                The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.

              • Name (string) --

                The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.

              • ExcludedRules (list) --

                The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

                  • Name (string) --

                    The name of the rule to exclude.

          • Action (dict) --

            The action that AWS WAF should take on a web request when it matches the rule's statement. Settings at the web ACL level can override the rule action setting.

            • Block (dict) --

              Instructs AWS WAF to block the web request.

            • Allow (dict) --

              Instructs AWS WAF to allow the web request.

            • Count (dict) --

              Instructs AWS WAF to count the web request and allow it.

          • OverrideAction (dict) --

            The action to use to override the rule's Action setting. You can use no override action, in which case the rule action is in effect, or count action, in which case, if the rule matches a web request, it only counts the match.

            • Count (dict) --

              Override the rule action setting to count.

            • None (dict) --

              Don't override the rule action setting.

          • VisibilityConfig (dict) --

            Defines and enables Amazon CloudWatch metrics and web request sample collection.

            • SampledRequestsEnabled (boolean) --

              A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

            • CloudWatchMetricsEnabled (boolean) --

              A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

            • MetricName (string) --

              A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action." You can't change a MetricName after you create a VisibilityConfig .

      • VisibilityConfig (dict) --

        Defines and enables Amazon CloudWatch metrics and web request sample collection.

        • SampledRequestsEnabled (boolean) --

          A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

        • CloudWatchMetricsEnabled (boolean) --

          A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

        • MetricName (string) --

          A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action." You can't change a MetricName after you create a VisibilityConfig .

      • Capacity (integer) --

        The web ACL capacity units (WCUs) currently being used by this web ACL.

        AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

    • LockToken (string) --

      A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

          Specifies that AWS WAF should block requests by default.

        • Allow (dict) --

          Specifies that AWS WAF should allow requests by default.

      • Description (string) --

        A friendly description of the Web ACL. You cannot change the description of a Web ACL after you create it.

      • Rules (list) --

        The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

        • (dict) --

          Note

          This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

          A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

          • Name (string) --

            A friendly name of the rule. You can't change the name of a Rule after you create it.

          • Priority (integer) --

            If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

          • Statement (dict) --

            The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

            • ByteMatchStatement (dict) --

              A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

              • SearchString (bytes) --

                A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

                Valid values depend on the areas that you specify for inspection in FieldToMatch :

                • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
                • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

                If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

                If you're using the AWS WAF API

                Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

                For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

                If you're using the AWS CLI or one of the AWS SDKs

                The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)
                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160
                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >
                    • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

              • PositionalConstraint (string) --

                The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

                CONTAINS

                The specified part of the web request must include the value of SearchString , but the location doesn't matter.

                CONTAINS_WORD

                The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

                • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
                • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
                EXACTLY

                The value of the specified part of the web request must exactly match the value of SearchString .

                STARTS_WITH

                The value of SearchString must appear at the beginning of the specified part of the web request.

                ENDS_WITH

                The value of SearchString must appear at the end of the specified part of the web request.

            • SqliMatchStatement (dict) --

              Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160
                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • XssMatchStatement (dict) --

              A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.

                    Specify NONE if you don't want any text transformations.

            • SizeConstraintStatement (dict) --

              A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

              If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

              If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

                • (string) --
            • RuleGroupReferenceStatement (dict) --

              A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

              You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the entity.

              • ExcludedRules (list) --

                The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

                  • Name (string) --

                    The name of the rule to exclude.

            • IPSetReferenceStatement (dict) --

              A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

              Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the IPSet that this statement references.

              A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

              Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

              • ARN (string) --

                The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

              • FieldToMatch (dict) --

                The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                • SingleHeader (dict) --

                  Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

                  • Name (string) --

                    The name of the query header to inspect.

                • SingleQueryArgument (dict) --

                  Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

                  • Name (string) --

                    The name of the query argument to inspect.

                • AllQueryArguments (dict) --

                  Inspect all query arguments.

                • UriPath (dict) --

                  Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

                • QueryString (dict) --

                  Inspect the query string. This is the part of a URL that appears after a ? character, if any.

                • Body (dict) --

                  Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

                  Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

                • Method (dict) --

                  Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

              • TextTransformations (list) --

                Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

                  • Priority (integer) --

                    Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

                  • Type (string) --

                    You can specify the following transformation types:

                    CMD_LINE

                    When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                    • Delete the following characters: " ' ^
                    • Delete spaces before the following characters: / (
                    • Replace the following characters with a space: , ;
                    • Replace multiple spaces with one space
                    • Convert uppercase letters (A-Z) to lowercase (a-z)
                    COMPRESS_WHITE_SPACE

                    Use this option to replace the following characters with a space character (decimal 32):

                    • f, formfeed, decimal 12
                    • t, tab, decimal 9
                    • n, newline, decimal 10
                    • r, carriage return, decimal 13
                    • v, vertical tab, decimal 11
                    • non-breaking space, decimal 160
                    COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                    HTML_ENTITY_DECODE

                    Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                    • Replaces (ampersand)quot; with "
                    • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                    • Replaces (ampersand)lt; with a "less than" symbol
                    • Replaces (ampersand)gt; with >
                    • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                    • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                    LOWERCASE

                    Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                    URL_DECODE

                    Use this option to decode a URL-encoded value.

                    NONE

                    Specify NONE if you don't want any text transformations.

            • RateBasedStatement (dict) --

              A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

              When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

              You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

              • An IP match statement with an IP set that specified the address 192.0.2.44.
              • A string match statement that searches in the User-Agent header for the string BadBot.

              In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

              You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • Limit (integer) --

                The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

              • AggregateKeyType (string) --

                Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

              • ScopeDownStatement (dict) --

                An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

            • AndStatement (dict) --

              A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

              • Statements (list) --

                The statements to combine with AND logic. You can use any statements that can be nested.

                • (dict) --

              A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .

              You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

              • VendorName (string) --

                The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.

              • Name (string) --

              • ExcludedRules (list) --

                The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.

                • (dict) --

                  Note

                  This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

                  Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

                  • Name (string) --

                    The name of the rule to exclude.

          • Action (dict) --

            The action that AWS WAF should take on a web request when it matches the rule's statement. Settings at the web ACL level can override the rule action setting.

            • Block (dict) --

              Instructs AWS WAF to block the web request.

            • Allow (dict) --

              Instructs AWS WAF to allow the web request.

            • Count (dict) --

              Instructs AWS WAF to count the web request and allow it.

          • OverrideAction (dict) --

            The action to use to override the rule's Action setting. You can use no override action, in which case the rule action is in effect, or count action, in which case, if the rule matches a web request, it only counts the match.

            • Count (dict) --

              Override the rule action setting to count.

            • None (dict) --

              Don't override the rule action setting.

          • VisibilityConfig (dict) --

            Defines and enables Amazon CloudWatch metrics and web request sample collection.

            • SampledRequestsEnabled (boolean) --

              A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

            • CloudWatchMetricsEnabled (boolean) --

              A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

            • MetricName (string) --

              A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action." You can't change a MetricName after you create a VisibilityConfig .

      • VisibilityConfig (dict) --

        Defines and enables Amazon CloudWatch metrics and web request sample collection.

        • SampledRequestsEnabled (boolean) --

          A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

        • CloudWatchMetricsEnabled (boolean) --

          A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

        • MetricName (string) --

          A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters.

      • Capacity (integer) --

        The web ACL capacity units (WCUs) currently being used by this web ACL.

        AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Enables the specified LoggingConfiguration , to start logging from a web ACL, according to the configuration provided.

You can access information about all traffic that AWS WAF inspects using the following steps:

  • Create an Amazon Kinesis Data Firehose. Create the data firehose with a PUT source and in the region that you are operating. If you are capturing logs for Amazon CloudFront, always create the firehose in US East (N. Virginia).

Note

Do not create the data firehose using a Kinesis stream as your source.

  • Associate that firehose to your web ACL using a PutLoggingConfiguration request.

When you successfully enable logging using a PutLoggingConfiguration request, AWS WAF will create a service linked role with the necessary permissions to write logs to the Amazon Kinesis Data Firehose. For more information, see Logging Web ACL Traffic Information in the AWS WAF Developer Guide .

            • Name (string) --

              The name of the query header to inspect.

          • SingleQueryArgument (dict) --

            Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

            • Name (string) --

              The name of the query argument to inspect.

          • AllQueryArguments (dict) --

            Inspect all query arguments.

          • UriPath (dict) --

            Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

          • QueryString (dict) --

            Inspect the query string. This is the part of a URL that appears after a ? character, if any.

          • Body (dict) --

            Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

            Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

          • Method (dict) --

            Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

    A friendly name of the IP set. You cannot change the name of an IPSet after you create it.

  • Scope (string) --

    [REQUIRED]

    Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

    To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

    • CLI - Specify the region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
    • API and SDKs - For all calls, use the Region endpoint us-east-1.
  • Id (string) --

    [REQUIRED]

    A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

Parameters
  • Name (string) --

    [REQUIRED]

    A friendly name of the rule group. You cannot change the name of a rule group after you create it.

  • Scope (string) --

    [REQUIRED]

    Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

    To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

    • CLI - Specify the region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
    • API and SDKs - For all calls, use the Region endpoint us-east-1.
  • Id (string) --

    [REQUIRED]

    A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

  • Description (string) -- A friendly description of the rule group. You cannot change the description of a rule group after you create it.
  • Rules (list) --

    The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

    • (dict) --

      Note

      This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

      A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

      • Name (string) -- [REQUIRED]

        A friendly name of the rule. You can't change the name of a Rule after you create it.

      • Priority (integer) -- [REQUIRED]

        If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

      • Statement (dict) -- [REQUIRED]

        The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

        • ByteMatchStatement (dict) --

          A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

          • SearchString (bytes) -- [REQUIRED]

            A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

            Valid values depend on the areas that you specify for inspection in FieldToMatch :

            • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
            • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

            If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

          • PositionalConstraint (string) -- [REQUIRED]

            The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

            CONTAINS

            The specified part of the web request must include the value of SearchString , but the location doesn't matter.

            CONTAINS_WORD

            The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

            • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
            • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
            EXACTLY

            The value of the specified part of the web request must exactly match the value of SearchString .

            STARTS_WITH

            The value of SearchString must appear at the beginning of the specified part of the web request.

            ENDS_WITH

            The value of SearchString must appear at the end of the specified part of the web request.

        • SqliMatchStatement (dict) --

          Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • XssMatchStatement (dict) --

          A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • SizeConstraintStatement (dict) --

          A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

          If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

          If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

            • (string) --
        • RuleGroupReferenceStatement (dict) --

          A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

          You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the entity.

          • ExcludedRules (list) --

            The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

        • IPSetReferenceStatement (dict) --

          A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

          Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the IPSet that this statement references.

        • RegexPatternSetReferenceStatement (dict) --

          A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

          Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

                NONE

                Specify NONE if you don't want any text transformations.

        • RateBasedStatement (dict) --

          A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

          When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

          You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

          • An IP match statement with an IP set that specified the address 192.0.2.44.
          • A string match statement that searches in the User-Agent header for the string BadBot.

          In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.

          You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • Limit (integer) -- [REQUIRED]

            The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopDownStatement , this limit is applied only to the requests that match the statement.

          • AggregateKeyType (string) -- [REQUIRED]

            Setting that indicates how to aggregate the request counts. Currently, you must set this to IP . The request counts are aggregated on IP addresses.

          • ScopeDownStatement (dict) --

            An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.

        • AndStatement (dict) --

          A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

          • Statements (list) -- [REQUIRED]

            The statements to combine with AND logic. You can use any statements that can be nested.

        • NotStatement (dict) --

          A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .

          • Statement (dict) --

            The statement to negate. You can use any statement that can be nested.

        • ManagedRuleGroupStatement (dict) --

          A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .

          You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • VendorName (string) -- [REQUIRED]

            The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.

          • Name (string) -- [REQUIRED]

            The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.

          • ExcludedRules (list) --

            The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

      • Action (dict) --

        The action that AWS WAF should take on a web request when it matches the rule's statement. Settings at the web ACL level can override the rule action setting.

        • Block (dict) --

          Instructs AWS WAF to block the web request.

        • Allow (dict) --

          Instructs AWS WAF to allow the web request.

        • Count (dict) --

          Instructs AWS WAF to count the web request and allow it.

      • OverrideAction (dict) --

        The action to use to override the rule's Action setting. You can use no override action, in which case the rule action is in effect, or count action, in which case, if the rule matches a web request, it only counts the match.

        • Count (dict) --

          Override the rule action setting to count.

        • None (dict) --

          Don't override the rule action setting.

      • VisibilityConfig (dict) -- [REQUIRED]

        Defines and enables Amazon CloudWatch metrics and web request sample collection.

        • SampledRequestsEnabled (boolean) -- [REQUIRED]

          A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

        • CloudWatchMetricsEnabled (boolean) -- [REQUIRED]

          A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

        • MetricName (string) -- [REQUIRED]

          A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action." You can't change a MetricName after you create a VisibilityConfig .

  • VisibilityConfig (dict) --

    [REQUIRED]

    Defines and enables Amazon CloudWatch metrics and web request sample collection.

    • SampledRequestsEnabled (boolean) -- [REQUIRED]

      A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.

    • CloudWatchMetricsEnabled (boolean) -- [REQUIRED]

      A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .

    • MetricName (string) -- [REQUIRED]

      A friendly name of the CloudWatch metric. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with length from one to 128 characters. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action." You can't change a MetricName after you create a VisibilityConfig .

  • LockToken (string) --

    [REQUIRED]

    A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

Updates the specified WebACL .

A Web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the Web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a Web ACL can be a combination of the types Rule , RuleGroup , and managed rule group. You can associate a Web ACL with one or more AWS resources to protect. The resources can be Amazon CloudFront, an Amazon API Gateway API, or an Application Load Balancer.

    [REQUIRED]

    Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

    To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

    • CLI - Specify the region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
    • API and SDKs - For all calls, use the Region endpoint us-east-1.
  • Id (string) --

    [REQUIRED]

    The unique identifier for the Web ACL. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

  • DefaultAction (dict) --

    [REQUIRED]

    The action to perform if none of the Rules contained in the WebACL match.

    • Block (dict) --

      Specifies that AWS WAF should block requests by default.

    • Allow (dict) --

      Specifies that AWS WAF should allow requests by default.

  • Description (string) -- A friendly description of the Web ACL. You cannot change the description of a Web ACL after you create it.
  • Rules (list) --

    The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

    • (dict) --

      Note

      This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

      A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

      • Name (string) -- [REQUIRED]

        A friendly name of the rule. You can't change the name of a Rule after you create it.

      • Priority (integer) -- [REQUIRED]

        If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.

      • Statement (dict) -- [REQUIRED]

        The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .

        • ByteMatchStatement (dict) --

          A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.

          • SearchString (bytes) -- [REQUIRED]

            A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.

            Valid values depend on the areas that you specify for inspection in FieldToMatch :

            • Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
            • UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .

            If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

          • PositionalConstraint (string) -- [REQUIRED]

            The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:

            CONTAINS

            The specified part of the web request must include the value of SearchString , but the location doesn't matter.

            CONTAINS_WORD

            The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:

            • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
            • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
            EXACTLY

            The value of the specified part of the web request must exactly match the value of SearchString .

            STARTS_WITH

            The value of SearchString must appear at the beginning of the specified part of the web request.

            ENDS_WITH

            The value of SearchString must appear at the end of the specified part of the web request.

        • SqliMatchStatement (dict) --

          Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • SizeConstraintStatement (dict) --

          A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes.

          If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.

          If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

          • FieldToMatch (dict) -- [REQUIRED]

            The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

            • SingleHeader (dict) --

              Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query header to inspect.

            • SingleQueryArgument (dict) --

              Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.

              • Name (string) -- [REQUIRED]

                The name of the query argument to inspect.

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

            • Method (dict) --

              Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.

          • ComparisonOperator (string) -- [REQUIRED]

            The operator to use to compare the request part to the size setting.

          • Size (integer) -- [REQUIRED]

            The size, in byte, to compare to the request part, after any transformations.

          • TextTransformations (list) -- [REQUIRED]

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

              • Priority (integer) -- [REQUIRED]

                Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

              • Type (string) -- [REQUIRED]

                You can specify the following transformation types:

                CMD_LINE

                When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

                • Delete the following characters: " ' ^
                • Delete spaces before the following characters: / (
                • Replace the following characters with a space: , ;
                • Replace multiple spaces with one space
                • Convert uppercase letters (A-Z) to lowercase (a-z)
                COMPRESS_WHITE_SPACE

                Use this option to replace the following characters with a space character (decimal 32):

                • f, formfeed, decimal 12
                • t, tab, decimal 9
                • n, newline, decimal 10
                • r, carriage return, decimal 13
                • v, vertical tab, decimal 11
                • non-breaking space, decimal 160
                COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

                HTML_ENTITY_DECODE

                Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

                • Replaces (ampersand)quot; with "
                • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
                • Replaces (ampersand)lt; with a "less than" symbol
                • Replaces (ampersand)gt; with >
                • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
                • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
                LOWERCASE

                Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

                URL_DECODE

                Use this option to decode a URL-encoded value.

                NONE

                Specify NONE if you don't want any text transformations.

        • GeoMatchStatement (dict) --

          A rule statement used to identify web requests based on country of origin.

          • CountryCodes (list) --

            An array of two-character country codes, for example, [ "US", "CN" ] , from the alpha-2 country ISO codes of the ISO 3166 international standard.

            • (string) --
        • RuleGroupReferenceStatement (dict) --

          A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

          You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the entity.

          • ExcludedRules (list) --

            The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

            • (dict) --

              Note

              This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

              Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.

              • Name (string) -- [REQUIRED]

                The name of the rule to exclude.

        • IPSetReferenceStatement (dict) --

          A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .

          Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the IPSet that this statement references.

        • RegexPatternSetReferenceStatement (dict) --

          A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .

          Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

          • ARN (string) -- [REQUIRED]

            The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

          • FieldToMatch (dict) -- [REQUIRED]

            • AllQueryArguments (dict) --

              Inspect all query arguments.

            • UriPath (dict) --

              Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

            • QueryString (dict) --

              Inspect the query string. This is the part of a URL that appears after a ? character, if any.

            • Body (dict) --

              Inspect the request body, which immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

              Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
