Explanation
AAA stands for Authentication, Authorization, and Accounting - a framework for controlling network access. RADIUS (Remote Authentication Dial-In User Service) and TACACS+ (Terminal Access Controller Access-Control System Plus) are both purpose-built AAA protocols used to centrally manage user authentication, authorize what resources they can access, and log their activity. Kerberos is an authentication protocol but is not an AAA framework. MS-CHAP is a challenge-response authentication protocol used in point-to-point connections, not a full AAA system. 802.1X is a port-based network access control standard that often uses RADIUS as its backend AAA server - it is the enforcement mechanism, not the AAA protocol itself.
