AWS CLI Command Reference

[ aws . iam ]

generate-service-last-accessed-details

Description

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 .

Options

--arn (string)

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.

Possible values:

  • SERVICE_LEVEL
  • ACTION_LEVEL

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To generate a service access report for a custom policy

The following generate-service-last-accessed-details example starts a background job to generate a report that lists the services accessed by IAM users and other entities with a custom policy named intern-boundary. You can display the report after it is created by running the get-service-last-accessed-details command.

aws iam generate-service-last-accessed-details \
    --arn arn:aws:iam::123456789012:policy/intern-boundary

Output:

{
    "JobId": "2eb6c2b8-7b4c-3xmp-3c13-03b72c8cdfdc"
}

Example 2: To generate a service access report for the AWS managed AdministratorAccess policy

The following generate-service-last-accessed-details example starts a background job to generate a report that lists the services accessed by IAM users and other entities with the AWS managed AdministratorAccess policy. You can display the report after it is created by running the get-service-last-accessed-details command.

aws iam generate-service-last-accessed-details \
    --arn arn:aws:iam::aws:policy/AdministratorAccess

Output:

{
    "JobId": "78b6c2ba-d09e-6xmp-7039-ecde30b26916"
}

Output

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 .
