Amazon managed policies for Amazon CloudTrail

To add permissions to users, groups, and roles, it is easier to use Amazon managed policies than to write policies yourself. It takes time and expertise to create IAM customer managed policies that provide your team with only the permissions they need. To get started quickly, you can use Amazon managed policies. These policies cover common use cases and are available in your Amazon Web Services account. For more information about Amazon managed policies, see Amazon managed policies in the IAM User Guide.

Amazon services maintain and update Amazon managed policies. You can't change the permissions in Amazon managed policies. Services occasionally add additional permissions to an Amazon managed policy to support new features. This type of update affects all identities (users, groups, and roles) where the policy is attached. Services are most likely to update an Amazon managed policy when a new feature is launched or when new operations become available. Services do not remove permissions from an Amazon managed policy, so policy updates won't break your existing permissions.

Additionally, Amazon supports managed policies for job functions that span multiple services. For example, the ReadOnlyAccess Amazon managed policy provides read-only access to all Amazon services and resources. When a service launches a new feature, Amazon adds read-only permissions for new operations and resources. For a list and descriptions of job function policies, see Amazon managed policies for job functions in the IAM User Guide.

Amazon managed policy: AWSCloudTrail_ReadOnlyAccess

A user identity that has the AWSCloudTrail_ReadOnlyAccess policy attached to its role can perform read-only actions in CloudTrail, such as Get*, List*, and Describe* actions on trails, CloudTrail Lake event data stores, or Lake queries.

Amazon managed policy: AWSServiceRoleForCloudTrail

The CloudTrailServiceRolePolicy policy allows Amazon CloudTrail to perform actions on organization trails and organization event data stores on your behalf. The policy includes required Amazon Organizations permissions for describing and listing the organization accounts and delegated administrators in an Amazon Organizations organization.

This policy additionally includes the required Amazon Glue and Amazon Lake Formation permissions to disable Lake federation on an organization event data store.

This policy is attached to the AWSServiceRoleForCloudTrail service-linked role that allows CloudTrail to perform actions on your behalf. You cannot attach this policy to your users, groups, or roles.
