Chapter 17. Remote Authentication Dial-In User Service (RADIUS)

In this chapter:

RADIUS Messages

RADIUS Message Exchanges

Summary

RADIUS is a simple client-server protocol that carries authentication, authorization, and accounting information between a network access server (NAS) and a centralized server. Examples of NASs include IEEE 802.11 wireless access points and servers that provide remote access connectivity to an organization’s network or the Internet.

A RADIUS client is a NAS that initiates RADIUS message exchanges for connection requests or accounting of connections. A RADIUS server receives and evaluates connection requests for authentication and authorization or stores accounting messages. A RADIUS proxy routes RADIUS connection requests ...
