BreezeMAX Wi² and BreezeACCESS Wi² System Manual 99
For a more secure network, the AP can implement one or a combination of the
following security mechanisms:
 Wired Equivalent Privacy (WEP) page 99
 IEEE 802.1X page 114
 Wireless MAC address filtering page 54
 WiFi Protected Access (WPA or WPA2) page 108
Both WEP and WPA security settings are configurable separately for each virtual
access point (VAP) interface. MAC address filtering, and RADIUS server settings
are global and apply to all VAP interfaces.
The security mechanisms that may be employed depend on the level of security
required, the network and management resources available, and the software
support provided on wireless clients.
A summary of wireless security considerations is listed in Table 4-6.

WEP Built-in support on all 802.11g
devices
 Provides only weak security
 Requires manual key management
WEP over 802.1X Requires 802.1X client support in
system or by add-in software
(support provided in Windows
2000 SP3 or later and Windows
XP)
 Provides dynamic key rotation for improved WEP
security
 Requires configured RADIUS server
 802.1X EAP type may require management of digital
certificates for clients and server
MAC Address
Filtering
Uses the MAC address of client
network card
 Provides only weak user authentication
 Management of authorized MAC addresses
 Can be combined with other methods for improved
security
 Optionally configured RADIUS server
