TACACS+ (Terminal Access Controller Access Control System) is an authentication protocol that allows a
remote access server to forward a user's logon password to an authentication server to determine whether
access can be allowed to a given system. TACACS+ and Remote Authentication Dial-In User Service
(RADIUS) protocols are more secure than the TACACS encryption protocol. TACACS+ is described in RFC
TACACS+ protocol is more reliable than RADIUS, as TACACS+ uses the Transmission Control Protocol
(TCP) whereas RADIUS uses the User Datagram Protocol (UDP). Also, RADIUS combines authentication
and authorization in a user profile, whereas TACACS+ separates the two operations.
