RADIUS is a protocol that enables a single server to become responsible for all remote access authentication, authorization, and auditing (or accounting) services.

RADIUS functions as a client/server system.

The remote user dials in or connects to, the remote access server, which acts as a RADIUS client, or network access server (NAS), and connects to a RADIUS server.

The RADIUS server performs authentication, authorization, and auditing (or accounting) functions and returns the information to the RADIUS client (which is remote access server running RADIUS client software); the connection is either established or rejected based on the information received.

  • RFC 2865 and RFC 2866 for RADIUS accounting
  • Very flexible and open ended.
  • Handles passwords, logins, etc. – lots of extensions
  • Uses UDP at the Transport Layer
