Using service-linked roles for CloudTrail
Amazon CloudTrail uses Amazon Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to CloudTrail. Service-linked roles are predefined by CloudTrail and include all the permissions that the service requires to call other Amazon services on your behalf.
