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

Match each component of the AAA security framework to its core administrative function.

  • AuthenticationVerifies the identity of a user or device before granting system entry.
  • AuthorizationDetermines the specific privileges, commands, and resources accessible to a user.
  • AccountingTracks, logs, and records user activities, command execution, and session durations.

Answer

Authentication maps to identity verification; Authorization maps to privilege and resource permission determination; Accounting maps to tracking, logging, and usage recording.
Authentication is responsible for verifying identity, Authorization restricts or allows actions based on permissions, and Accounting logs session and command activity for auditing purposes.

Step-by-Step Solution

1
Identify the primary role of Authentication in the AAA framework.
Authentication answers 'Who are you?' by verifying credentials against a local database or remote AAA server.
Establishing identity is the essential first step before any network privileges can be evaluated.
2
Identify the primary role of Authorization in the AAA framework.
Authorization answers 'What are you allowed to do?' by specifying permissible CLI commands or VLAN assignments.
Access control policy enforcement requires explicit permission checks per user session.
3
Identify the primary role of Accounting in the AAA framework.
Accounting answers 'What did you do and for how long?' by capturing log entries and session statistics.
Auditing and compliance depend on maintaining accurate time-stamped logs of administrative actions.
