What is the purpose of the authorization mechanism in a security system?

The authorization mechanism is responsible for determining the user's access rights to system resources after their identity has been established (authentication).

The main purpose of authorization is to control what actions and data a specific user or role is permitted to perform. This ensures security and prevents unauthorized access.

For example, in a web application, after a user logs in, the system checks whether they can view certain pages, modify data, or perform administrative functions based on their rights.

Thus, authorization guarantees that each user interacts with the system within their authorized scope.
