arn

The ARN of the entity that the policy is attached to. The ARN format depends on the policy type:

• For identity, session, and permissions boundary policies, this is the principal ARN (for example, an IAM role or user ARN).

• For resource-based policies, this is the resource ARN.

• For organization control policies (SCPs and RCPs), this is the AWS Organizations ARN of the account, organizational unit, or root.
