TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS Plus ( TACACS+ ) is a protocol developed by Cisco and released as an open standard beginning in 1993.
A terminal access controller (TAC) is a host computer that accepts terminal connections, usually from dial-up lines, and that allows the user to invoke Internet remote log-on procedures, such as Telnet.
Its most notable applications are remote login and command-line execution. SSH was designed for Unix-like operating systems as a replacement for Telnet and unsecured remote Unix shell protocols, such as the Berkeley Remote Shell (rsh) and the related rlogin and rexec protocols, which all use insecure, plaintext methods of authentication, like ...

A tap is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. The network tap has (at least) three ports: an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic (send and receive data streams) through unimpeded in real time, but also copies that ...

In telecommunications, a remote digital terminal (RDT) typically accepts E1, T1 or OC-3 digital lines to communicate with a telephone Access network (AN) or telephone exchange (Local Digital Switch, LDS) on one side, and forms a local exchange (LE) on the other, which is connected to "plain old telephone service" lines.
