How should an organization design a comprehensive IAM governance strategy combining permission boundaries, service control policies, and regular access reviews across a growing organization?
AdvancedAnswer
A comprehensive IAM governance strategy typically layers permission boundaries to cap the maximum permissions any IAM role or user within a specific team can ever be granted, even by a well meaning but overly generous administrator, combines this with organization wide service control policies that enforce non negotiable baseline restrictions across every account, and establishes a recurring cadence of access reviews using tools like IAM Access Analyzer and Credential Reports to identify and remove unused permissions, stale credentials, and overly broad roles before they become a genuine security risk.
