Chapter 16 Authentication Server

Sent by an access point requesting authentication.

Access-Reject

Sent by a RADIUS server rejecting access.

Access-Accept

Sent by a RADIUS server allowing access.

Access-Challenge

Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message.

The following types of RADIUS messages are exchanged between the ZyWALL and the RADIUS server for user accounting:

Accounting-Request

Sent by the access point requesting accounting.

Accounting-Response

Sent by the RADIUS server to indicate that it has started or stopped accounting.

In order to ensure network security, the ZyWALL and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access.
