Configuring Device Security Defining Authentication 4 Defining TACACS+ The devices provide Terminal Access Controller Access Control System (TACACS+) client support. TACACS+ provides centralized security for validation of users accessing the device. 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 server checks the user privileges. The TACACS+ protocol ensures network integrity through encrypted protocol exchanges between the device 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. The TACACS+ Page contains fields for assigning the Default Parameters for the TACACS+ servers. TACACS+ is supported on IPv4 and not on IPv6.
