Wireless Security
This chapter describes how to use the MAC Filter, 802.1x, Local User Database and RADIUS
to configure wireless security on your ZyAIR.
6.1 Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless
stations, access points and the wired network.
The figure below shows the possible wireless security levels on your ZyAIR. EAP (Extensible
Authentication Protocol) is used for authentication and utilizes dynamic 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
Figure 29 ZyAIR Wireless Security Levels
If you do not enable any wireless security on your ZyAIR, your network is accessible to any
wireless networking device that is within range.
6.2 WEP Overview
WEP (Wired Equivalent Privacy) as specified in the IEEE 802.11 standard provides methods
for both data encryption and wireless station authentication.
