What does AAA stand for?

• A. Authorization, Authentication, and Accounting
• B. Authentication, Authorization, and Accounting
• C. Authentication, Access, and Accounting
• D. Authenticating, Authorizing, and Accounting

Answer: (B)

AAA stands for Authentication, Authorization, and Accounting. Authentication verifies who you are, using credentials like a password, token, or certificate. After identity is verified, Authorization decides what you are allowed to do, enforcing permissions and access controls. Accounting tracks what was done, by whom, and when, providing an audit trail for monitoring, billing, or forensics. This combination is standard in network access, VPNs, Wi‑Fi, and enterprise systems to manage access and keep records. The other phrasings aren’t the conventional expansion: using Authenticating or Authorizing uses different grammatical forms, and listing Authorization before Authentication implies granting rights without first confirming identity.
