No Root Access Keys

The root user has complete access to all services and resources in an AWS account. AWS Access Keys provide programmatic access to a given account.

CIS recommends that all access keys be associated with the root user be removed. Removing access keys associated with the root user limits vectors that the account can be compromised by. Removing the root user access keys also encourages the creation and use of role-based accounts that are least privileged.
