Defining TACACS+ Authentication

Terminal Access Controller Access Control System (TACACS+) provides centralized security user access
validation. The system supports up-to two TACACS+ servers.
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+ new servers.
