1.21 Ensure IAM users are managed centrally via identity federation or AWS Organizations for multi-account environments

Information

In multi-account environments, IAM user centralization facilitates greater user control. User access beyond the initial account is then provided via role assumption. Centralization of users can be accomplished through federation with an external identity provider or through the use of AWS Organizations.

Rationale:

Centralizing IAM user management to a single identity store reduces complexity and thus the likelihood of access management errors.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

The remediation procedure will vary based on the individual organization's implementation of identity federation and/or AWS Organizations with the acceptance criteria that no non-service IAM users, and non-root accounts, are present outside the account providing centralized IAM user management.
