TACACS
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. When the authentication session is completed, an
authorization session starts using the authenticated user name. The TACACS server
checks the user privileges.
The TACACS protocol ensures network security through encrypted protocol exchanges
between the device and TACACS server.
