Terminal Access Controller Access Control System. Authentication protocol from DDN providing remote access security and related services.
Terminal Access Controller Access Control System plus. A security protocol that provides detailed accounting information and flexible administrative control over authentication and authorization processes. TACACS+ is facilitated through authentication, authorization, and accounting (AAA) and can be enabled only through AAA commands.
Terminal Access Controller Access Control System, a an authentication server that validates user IDs and passwords, thus controlling entry into systems.
(Terminal Access Controller Access Control System) A protocol for authenticating users attempting to gain access to servers, networks, and remote-access servers. Similar to but less secure than RADIUS and TACACS+.
(Terminal Access Controller Access Control System) Authentication protocol, developed by the DDN community, that provides remote access authentication and related services, such as event logging. User passwords are administered in a central database rather than in individual routers, providing an easily scalable network security solution.
Terminal Access Controller Access Control System Plus. Proprietary Cisco enhancement to Terminal Access Controller Access Control System (TACACS). Provides additional support for authentication, authorization, and accounting. See also TACACS in main glossary.
Terminal Access Controller Access Control System Plus. TACACS+ is a security application that provides centralized validation of users attempting to gain access to a router or network access server.
Terminal Access Controller Access Control Systems. A protocol that specifies a simple user name/password system for authentication into a network. TACACS+ is an extension that offers encryption and an optional challenge/response.
Terminal Access Controller Access Control System Plus. Authentication method for validating users who attempt to access the router using telnet.
Terminal Access Controller Access-Control System (TACACS) is a remote authentication protocol that is used to communicate with an authentication server commonly used in UNIX networks. TACACS allows a remote access server to communicate with an authentication server in order to determine if the user has access to the network.
