Chapter 7 Wireless Security Configuration

7.7 Wireless Client WPA Supplicants

A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client, and Meetinghouse Data Communications' AEGIS client.

The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it.

7.8 Wireless Security Effectiveness

The following figure shows the relative effectiveness of these wireless security methods available on your ZyXEL Device. EAP (Extensible Authentication Protocol) is used for authentication and utilizes static WEP key exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or your LAN to provide authentication service for wireless stations.
