In a typical network that uses RADIUS, the authentication and authorization process goes like this: Authentication ProcessĪs a client-server networking protocol, RADIUS has client and server components. To ensure that RADIUS runs on a secure network connection, there have been past initiatives to make it work with Transmission Control Protocol (TCP), but these have not gone beyond the experimental stage. When this happens, the RADIUS client sends another request to the server. However, this can also lead to request timeouts in case of poor network quality. Since UDP does not require a reliable connection across a network, using RADIUS means minimal network overhead. RADIUS is a client-server networking protocol with AAA management features that uses the connectionless User Datagram Protocol (UDP) for its transport layer and uses port 1812 for authentication and port 1813 for authorization. While users are connected to your network, NPS logs their activities as part of its RADIUS accounting role. Under this setup, your network access server (NAS) acts as a RADIUS client and sends all connection requests from users to a RADIUS server running NPS on Windows, which then provides authentication and authorization information back to the NAS. NPS provides centralized authentication, authorization, and accounting (AAA) capabilities to your network. Network Policy Server (NPS) is Microsoft’s implementation of a Remote Authentication Dial-In User Service (RADIUS) server.
