TACACS+ The Terminal Access Controller Access Control System (TACACS+) security protocol is a recent protocol
developed by Cisco. It provides detailed accounting information and flexible administrative control over the
authentication and authorization processes. TACACS+ allows for a single access control server (the TACACS+
daemon) to provide authentication, authorization, and accounting services independently. Each service can be
tied into its own database to take advantage of other services available on that server or on the network,
depending on the capabilities of the daemon. There is a draft RFC detailing this protocol. Further information on
configuring remote TACACS+ servers can be found at the following sites:
