4.7.5 TACACS+
TACACS+ (Terminal Access Controller Access-Control System Plus) is a protocol which provides access control for routers,
network access servers and other networked computing devices via one or more centralized servers. TACACS+ provides
separate authentication, authorization and accounting services.
TACACS+ is based on TACACS, but, in spite of its name, it is an entirely new protocol which is incompatible with any previous
version of TACACS. TACACS+ and RADIUS have generally replaced the earlier protocols in more recently built or updated
networks, although TACACS and XTACACS are still running on many older systems.
Whereas RADIUS combines authentication and authorization in a user profile, TACACS+ separates the two operations. Another
difference is that TACACS+ uses the TCP while RADIUS uses the UDP. Most administrators recommend using TACACS+
because TCP is seen as a more reliable protocol.
The extensions to the TACACS+ protocol provide for more types of authentication requests and more types of response codes
than were in the original specification.
The TACACS+ server configuration screen in Figure 4-7-18 appears.
