12 TACACS
TACACS (Terminal Access Controller Access Control System), widely used in network
environments, is a client/server protocol that enables remote access servers to communicate with
a central server to authenticate dial-in users and authorize their access to the requested system
or service. It is commonly used for providing Network Access Security (NAS). NAS ensures
secure access from remotely connected users. TACACS implements the TACACS Client and
provides the Authentication, Authorization and Accounting (AAA) functionalities.
TACACS is used for several reasons:
Facilitates centralized user administration.
Uses TCP for transport to ensure reliable delivery.
Supports inbound authentication, outbound authentication and change password request
for the
Authentication service.
Provides some level of protection against an active attacker.
The list of CLI commands for the configuration of TACACS is as follows:
tacacs-server host
tacacs use-server address
tacacs-server retransmit
