TACACS+
Terminal Access Controller Access Control System
(TACACS+) provides
centralized security user access validation.
TACACS+ provides a centralized user management system, while still retaining
consistency with RADIUS and other authentication processes. TACACS+ provides
the following services:
• Authentication — Provides authentication during login and via user names
and user-defined passwords.
• Authorization — Performed at login. Once the authentication session is
completed, an authorization session starts using the authenticated user
name.
The TACACS+ protocol ensures network integrity through encrypted protocol
exchanges between the client and TACACS+ server.
The TACACS+ default parameters are user-assigned defaults. The default settings
are applied to newly defined TACACS+ servers. If default values are not defined,
the system defaults are applied to the new TACACS+ server.
To define TACACS+ server authentication settings:
STEP 1 Click Network Security > TACACS+. The
