Authorization
The process of granting or restricting access to resources based on an identity’s permissions.
Authorization determines what an authenticated user, service, or device is allowed to do within a system.
Typical authorization models include role-based access control (RBAC), attribute-based access control (ABAC), or custom permission systems. Good authorization design limits access to the minimum necessary for each role (the principle of least privilege).
In compliance and security programs, authorization rules and reviews are key to protecting sensitive data and preventing privilege misuse.
