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

Rating 🐑 - Low

Description

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

Vulnerability

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

Remediation

Follow the AWS best practices to setup SSO.
