Configure IAM permission boundaries in AWS to delegate role creation to developers while enforcing maximum privilege limits set by the security team. Use when configureing iam permission boundaries in aws to delegate role creation.
IAM permission boundaries are an advanced AWS feature that sets the maximum permissions an identity-based policy can grant to an IAM entity (user or role). They enable centralized security teams to safely delegate IAM role and policy creation to application developers without risking privilege escalation. The effective permissions of an entity are the intersection of its identity-based policies and its permission boundary -- even if an identity policy grants AdministratorAccess, the permission boundary restricts it to only the allowed actions.

Step 4: Prevent Privilege Escalation
The boundary must include deny statements to prevent developers from:
