Process Network Policy Server RADIUS Server

The RADIUS server is a network protocol that provides centralized authentication, authorization, and accounting management for users who use and connect to a network server. The Livingston Enterprises developed this server in 1991. It is most commonly used by Internet Server Providers to manage access to internal networks, wireless network, Internet and integrated email services. RADIUS is a protocol that uses TCP or UDP as transport and runs on the application server. This server usually runs in the background process on a Microsoft or UNIX server.

“RADIUS” stands for “Remote Authentication Dial-In User Service”. It is a client/server protocol and software that allows communication between remote access servers and a central server to authenticate dial-in users and authorize or allow their access to the requested device or system.

It is a networking protocol operating on port 1812 that provides centralized “AAA” or Triple A or Authentication, Authorization, and Accounting management for users who connect and use a network service. It was developed in 1991 by Livingston Enterprises, Inc. as an accounting protocol and access server authentication and later brought into the IETF standards or the “Internet Engineering Task Force”.

It is used by many Internet Service Providers. When you dial-in to the ISP, you have to enter a username and password. These details or information you enter is passed or transmitted to a RADIUS server which then verifies that the information is correct and then authorizes the access to the ISP system.
