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 dedicated AAA protocols. RADIUS is commonly used for network access (Wi-Fi, VPNs, dial-up) and combines authentication and authorization in a single response. TACACS+ separates authentication, authorization, and accounting into distinct processes, making it more granular - it is preferred for device administration (e.g., managing routers and switches). Kerberos is an authentication protocol but is not a AAA system. PKI is a certificate infrastructure. TKIP/AES are encryption standards. MS-CHAP is a point-to-point authentication protocol, not a AAA framework.
