generate_service_last_accessed_details#

IAM.Client.generate_service_last_accessed_details(**kwargs)#

Generates a report that includes details about when an IAM resource (user, group, role, or policy) was last used in an attempt to access Amazon Web Services services. Recent activity usually appears within four hours. IAM reports activity for at least the last 400 days, or less if your Region began supporting this feature within the last year. For more information, see Regions where data is tracked. For more information about services and actions for which action last accessed information is displayed, see IAM action last accessed information services and actions.

Warning

The service last accessed data includes all attempts to access an Amazon Web Services API, not just the successful ones. This includes all attempts that were made using the Amazon Web Services Management Console, the Amazon Web Services API through any of the SDKs, or any of the command line tools. An unexpected entry in the service last accessed data does not mean that your account has been compromised, because the request might have been denied. Refer to your CloudTrail logs as the authoritative source for information about all API calls and whether they were successful or denied access. For more information, see  Logging IAM events with CloudTrail in the IAM User Guide.

The GenerateServiceLastAccessedDetails operation returns a JobId. Use this parameter in the following operations to retrieve the following details from your report:

  • GetServiceLastAccessedDetails – Use this operation for users, groups, roles, or policies to list every Amazon Web Services service that the resource could access using permissions policies. For each service, the response includes information about the most recent access attempt. The JobId returned by GenerateServiceLastAccessedDetail must be used by the same role within a session, or by the same user when used to call GetServiceLastAccessedDetail.

  • GetServiceLastAccessedDetailsWithEntities – Use this operation for groups and policies to list information about the associated entities (users or roles) that attempted to access a specific Amazon Web Services service.

To check the status of the GenerateServiceLastAccessedDetails request, use the JobId parameter in the same operations and test the JobStatus response parameter.

For additional information about the permissions policies that allow an identity (user, group, or role) to access specific services, use the ListPoliciesGrantingServiceAccess operation.

Note

Service last accessed data does not use other policy types when determining whether a resource could access a service. These other policy types include resource-based policies, access control lists, Organizations policies, IAM permissions boundaries, and STS assume role policies. It only applies permissions policy logic. For more about the evaluation of policy types, see Evaluating policies in the IAM User Guide.

For more information about service and action last accessed data, see Reducing permissions using service last accessed data in the IAM User Guide.

Request Syntax

response = client.generate_service_last_accessed_details(
    Arn='string',
    Granularity='SERVICE_LEVEL'|'ACTION_LEVEL'
)
Parameters:

  • Arn (string) –

    [REQUIRED]

    The ARN of the IAM resource (user, group, role, or managed policy) used to generate information about when the resource was last used in an attempt to access an Amazon Web Services service.

  • Granularity (string) – The level of detail that you want to generate. You can specify whether you want to generate information about the last attempt to access services or actions. If you specify service-level granularity, this operation generates only service data. If you specify action-level granularity, it generates service and action data. If you don’t include this optional parameter, the operation generates service data.

Return type:

dict

Returns:

Response Syntax

{
    'JobId': 'string'
}

Response Structure

  • (dict) –

    • JobId (string) –

      The JobId that you can use in the GetServiceLastAccessedDetails or GetServiceLastAccessedDetailsWithEntities operations. The JobId returned by GenerateServiceLastAccessedDetail must be used by the same role within a session, or by the same user when used to call GetServiceLastAccessedDetail.

Exceptions

  • IAM.Client.exceptions.NoSuchEntityException

  • IAM.Client.exceptions.InvalidInputException

Examples

The following operation generates a report for the policy: ExamplePolicy1

response = client.generate_service_last_accessed_details(
    Arn='arn:aws:iam::123456789012:policy/ExamplePolicy1',
)

print(response)

Expected Output:

{
    'JobId': 'examplef-1305-c245-eba4-71fe298bcda7',
    'ResponseMetadata': {
        '...': '...',
    },
