Chapter 7    
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. 
7.1 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. Dynamic WEP key exchange is not available on 
the ZyAIR B-2000. 
 
Figure 7-1 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.  
7.2 WEP 
Overview 
WEP (Wired Equivalent Privacy) as specified in the IEEE 802.11 standard provides methods for both data 
encryption and wireless station authentication.
