AAA stands for?

• A. Authentication, Authorization, and Accounting
• B. Authentication, Authorization, and Access
• C. AAA stands for Authentication, Authorization, and Accounting
• D. Authentication, Identity, and Accounting

Answer: (C)

AAA represents three steps in how access is controlled and tracked: Authentication, Authorization, and Accounting. Authentication is about proving who you are—checking credentials like a username and password, a token, or biometrics. Once your identity is established, Authorization decides what you’re allowed to do or access, such as which systems or data you can reach and what actions you can perform. Accounting then records what happened during the session—when you connected, how long you were active, and what resources you used—so there’s a trail for auditing and accountability. This combination is standard in many network and security systems (for example, in VPNs or directory services) because it covers who you are, what you’re permitted to do, and what you did, which is essential for secure access control. The other phrasing options replace or omit parts of the trio (like Access or Identity) and don’t reflect the established acronym.
