Service-linked role permissions for GuardDuty

GuardDuty uses the service-linked role (SLR) named AWSServiceRoleForAmazonGuardDuty. The SLR allows GuardDuty to perform the following tasks. It also allows GuardDuty to include the retrieved metadata belonging to the EC2 instance in the findings that GuardDuty may generate about the potential threat. The AWSServiceRoleForAmazonGuardDuty service-linked role trusts the guardduty.amazonaws.com service to assume the role.

The permission policies help GuardDuty perform the following tasks:

Use Amazon EC2 actions to manage and retrieve information about your EC2 instances, images, and networking components such as VPCs, subnets, transit gateways, and security groups.
Use AWS Systems Manager actions to manage SSM associations on Amazon EC2 instances when you enable GuardDuty Runtime Monitoring with automated agent for Amazon EC2. When GuardDuty automated agent configuration is disabled, GuardDuty considers only those EC2 instances that have an inclusion tag (GuardDutyManaged:true).
Use AWS Organizations actions to describe associated accounts and organization ID.
Use Amazon S3 actions to retrieve information about S3 buckets and objects.
Use AWS Lambda actions to retrieve information about your Lambda functions and tags.
Use Amazon EKS actions to manage and retrieve information about the EKS clusters and manage Amazon EKS add-ons on EKS clusters. The EKS actions also retrieve the information about the tags associated to GuardDuty.
Use IAM to create the Service-linked role permissions for Malware Protection after Malware Protection has been enabled.
Use Amazon ECS actions to manage and retrieve information about the Amazon ECS clusters, and manage the Amazon ECS account setting with guarddutyActivate. The actions pertaining to Amazon ECS also retrieve the information about the tags associated with GuardDuty.

The role is configured with the following AWS managed policy, named AmazonGuardDutyServiceRolePolicy.

The following is the trust policy that is attached to the AWSServiceRoleForAmazonGuardDuty service-linked role:

      "Principal": {

    }
  ]
}

For details about updates to the AmazonGuardDutyServiceRolePolicy policy, see GuardDuty updates to AWS managed policies. For automatic alerts about changes to this policy, subscribe to the RSS feed on the Document history page.

Creating a service-linked role for GuardDuty

The AWSServiceRoleForAmazonGuardDuty service-linked role is automatically created when you enable GuardDuty for the first time or enable GuardDuty in a supported Region where you previously didn't have it enabled. You can also create the service-linked role manually using the IAM console, the AWS CLI, or the IAM API.

Important

The service-linked role that is created for the GuardDuty delegated administrator account doesn't apply to the member GuardDuty accounts.

You must configure permissions to allow an IAM principal (such as a user, group, or role) to create, edit, or delete a service-linked role. For the AWSServiceRoleForAmazonGuardDuty service-linked role to be successfully created, the IAM principal that you use GuardDuty with must have the required permissions. To grant the required permissions, attach the following policy to this user, group, or role:

Note

Replace the sample account ID in the following example with your actual AWS account ID.

    "Version": "2012-10-17",
    "Statement": [
        {

                }
            }
        },
        {
            "Effect": "Allow",
            "Action": [
                "iam:PutRolePolicy",

        }
    ]
}

For more information about creating the role manually, see Creating a service-linked role in the IAM User Guide.

Editing a service-linked role for GuardDuty

GuardDuty doesn't allow you to edit the AWSServiceRoleForAmazonGuardDuty service-linked role. After you create a service-linked role, you can't change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see Editing a service-linked role in the IAM User Guide.

Deleting a service-linked role for GuardDuty

If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don't have an unused entity that isn't actively monitored or maintained.

Important

If you have enabled Malware Protection, deleting AWSServiceRoleForAmazonGuardDuty doesn't automatically delete AWSServiceRoleForAmazonGuardDutyMalwareProtection. If you want to delete AWSServiceRoleForAmazonGuardDutyMalwareProtection, see Deleting a service-linked role for Malware Protection.

You must first disable GuardDuty in all Regions where it is enabled in order to delete the AWSServiceRoleForAmazonGuardDuty. If the GuardDuty service isn't disabled when you try to delete the service-linked role, the deletion fails. For more information, see Suspending or disabling GuardDuty.

When you disable GuardDuty, the AWSServiceRoleForAmazonGuardDuty doesn't get deleted automatically. If you enable GuardDuty again, it'll start using the existing AWSServiceRoleForAmazonGuardDuty.

To manually delete the service-linked role using IAM

Use the IAM console, the AWS CLI, or the IAM API to delete the AWSServiceRoleForAmazonGuardDuty service-linked role. For more information, see Deleting a service-linked role in the IAM User Guide.

Supported AWS Regions

Amazon GuardDuty supports using the AWSServiceRoleForAmazonGuardDuty service-linked role in all the AWS Regions where GuardDuty is available. For a list of Regions where GuardDuty is currently available, see Amazon GuardDuty endpoints and quotas in the Amazon Web Services General Reference.
