The AAA framework serves which function in access management?

• A. It validates credentials, controls access, and records usage
• B. It only authenticates users
• C. It replaces physical security
• D. It manages encryption keys

Answer: (A)

AAA in access management covers Authentication, Authorization, and Accounting. Authentication verifies that a user or device is who they claim to be, using credentials like passwords, tokens, or biometrics. After identity is established, Authorization decides what the user is permitted to do and which resources they can access, enforcing the appropriate permissions and access control policies. Accounting records what happens—logging and auditing sessions, actions taken, and resource usage—for monitoring, billing, or forensic purposes. Together, these functions ensure that access is granted to the right individuals and tracked for accountability. The other options don’t fit because authentication is only one part of AAA, AAA doesn’t replace physical security, and managing encryption keys is a separate cryptographic function handled by key management systems rather than AAA.
