Azure RBAC Explained: Roles, Scope, and Why Least Privilege Breaks Down

Azure RBAC uses a principal + role + scope model to control access across Azure resources. While it provides a solid foundation for access control, it does not automatically enforce least privilege — broad roles like Contributor and Owner get assigned at high scopes for convenience and are rarely revisited. Service principals and managed identities accumulate standing permissions that outlive their projects and rarely appear in access reviews. The post covers RBAC building blocks, common failure patterns (inherited access, non-human identity sprawl, overly broad roles), and best practices including narrowing scope, capping subscription Owners, using just-in-time access via Microsoft Entra PIM, and auditing dormant identities. It concludes by noting that native Azure controls reflect configured state, not actual usage, and promotes a usage-based approach to continuously enforce least privilege.
