Chapter 4 Security Setup
Security Overview
When you enable EAP on your access points and client devices,
authentication to the network occurs in the steps shown in Figure 4-2:
Figure 4-2 Sequence for EAP Authentication
In steps 1 through 9 in Figure 4-2, a wireless client device and a RADIUS
server on the wired LAN use 802.1x and EAP to perform a mutual
authentication through the access point. The RADIUS server sends an
authentication challenge to the client. The client uses a one-way encryption
of the user-supplied password to generate a response to the challenge and
sends that response to the RADIUS server. Using information from its user
database, the RADIUS server creates its own response and compares that to
the response from the client. When the RADIUS server authenticates the
client, the process repeats in reverse, and the client authenticates the RADIUS
server.
