Difficulty: EasyAAA Framework Concepts (Authentication, Authorization, Accounting)

A network administrator needs to restrict which specific CLI commands an engineer can execute on a router after logging in. Which AAA component is responsible for controlling the specific actions and commands a user is allowed to perform?

  1. AuthorizationAnswer
  2. B
    Authentication
  3. C
    Accounting
  4. D
    Auditing

Answer

Authorization is the AAA component responsible for specifying permissions and restricting user actions or command execution on a network device.
Authorization is the functional pillar of AAA that determines user rights, privilege levels, and allowable commands after identity has been established.

Step-by-Step Solution

1
Identify the primary functions of the three pillars of the AAA framework
Authentication proves identity (Who are you?), Authorization grants permissions (What can you do?), and Accounting tracks actions (What did you do?).
Understanding the separation of roles within the AAA framework is essential for network access administration.
2
Match the administrator's requirement to the correct AAA function
Restricting CLI command execution requires privilege and permission enforcement, which falls under Authorization.
Authorization explicitly defines command access levels and privilege levels for an authenticated user.
