Explanation

RADIUS (Remote Authentication Dial-In User Service) was specifically designed for centralizing authentication, authorization, and accounting (AAA) for remote access scenarios such as VPN, dial-up, and wireless connections. TACACS+ is primarily used for device administration (e.g., authenticating to routers and switches). XTACACS is an outdated Cisco proprietary extension of TACACS. Kerberos is a ticket-based authentication protocol used in enterprise LAN environments like Active Directory, not specifically for remote access.
