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.
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.
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.
