In 1984, a U.S. military research institute designed the earliest TACACS protocol (RFC 927) to automate identity authentication in MILNET, allowing a user who has logged in to a host to connect to another host on the same network without being re-authenticated. Later, Cisco supported TACACS on its network products and extended TACACS (RFC 1492). 802.1x is a standard that defines a framework for centralized port-based authentication. It is proprietary of CISCO, hence it can be used only for CISCO devices and networks. It uses port number 1812 for authentication and authorization and 1813 for accounting.
