GenerateServiceLastAccessedDetails - AWS Identity and Access Management

GenerateServiceLastAccessedDetails

Generates a report that includes details about when an IAM resource (user, group, role, or policy) was last used in an attempt to access AWS 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.

Important

The service last accessed data includes all attempts to access an AWS API, not just the successful ones. This includes all attempts that were made using the AWS Management Console, the AWS 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 AWS 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 AWS 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, AWS Organizations policies, IAM permissions boundaries, and AWS 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 Parameters

For information about the parameters that are common to all actions, see Common Parameters.

Arn

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 AWS service.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Required: Yes

Granularity

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.

Type: String

Valid Values: SERVICE_LEVEL | ACTION_LEVEL

Required: No

Response Elements

The following element is returned by the service.

JobId

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.

Type: String

Length Constraints: Fixed length of 36.

Errors

For information about the errors that are common to all actions, see Common Errors.

InvalidInput

The request was rejected because an invalid or out-of-range value was supplied for an input parameter.

HTTP Status Code: 400

NoSuchEntity

The request was rejected because it referenced a resource entity that does not exist. The error message describes the resource.

HTTP Status Code: 404
