TACACS+ server
In recent years, remote network access has shifted from terminal access to LAN access. Users connect to their corporate network (using notebooks or home PCs) with computers that use complete network connections and have the same level of access to the corporate network resources as if they were physically in the office. These connections are made through a remote access server. As remote access technology has evolved, the need for network access security has become increasingly important.
Terminal Access Controller Access-Control System (TACACS) is a remote authentication protocol that provides access control for routers, network access servers, and other networked computing devices via one or more centralized servers. TACACS allows a client to accept a user name and password and send a query to a TACACS authentication server. The server host determines whether to accept or deny the request and sends a response back that allows or denies network access to the user. The default TCP port for a TACACS server is 49.
For more information about TACACS servers, see the FortiGate documentation.
