During which step of the AAA process is authorization implemented?

• A. Immediately after successful authentication against an AAA data source
• B. During the initial connection setup
• C. Before user authentication is performed
• D. After password validation is completed

Answer: (A)

Authorization is a key step in the AAA (Authentication, Authorization, and Accounting) framework that determines what resources a user or device can access after they have been authenticated. The authorization process is implemented immediately after the successful authentication against an AAA data source. This means that once the user’s identity is confirmed—typically by checking credentials like a username and password—the system then determines what level of access or permissions are granted to that user. In practical terms, this step uses policies, roles, or rules that are defined in the AAA configuration to allow or restrict access to various resources, services, or commands based on the authenticated user’s rights. For example, a user who is authenticated as an administrator would have different permissions compared to a standard user. The other steps mentioned do not pertain to authorization because they occur either before authentication or do not align with the sequence of the AAA process. During connection setup, user credentials have not yet been validated, and before authentication begins, the system doesn’t have enough information to grant access. Thus, the focus on successful authentication as a precursor to authorization is central to the AAA framework's structure.
