Radio Interface

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 the following table.

Security	Client	Implementation Considerations
Mechanism	Support
WEP	Built-in support on all	•	Provides only weak security
	802.11a, 802.11b and	• Requires manual key management
	802.11g devices
WEP over	Requires 802.1x client	•	Provides dynamic key rotation for
802.1x	support in system or by		improved WEP security
	add-in software	•	Requires configured RADIUS server
	(native support provided	•	802.1x EAP type may require
	in Windows XP)		management of digital certificates for
			clients and server
MAC Address	Uses the MAC address	• Provides only weak user
Filtering	of client network card		authentication
		• Management of authorized MAC
			addresses
		• Can be combined with other methods
			for improved security
		•	Optionally configured RADIUS server
WPA over	Requires WPA-enabled	• Provides robust security in WPA-only
802.1x mode	system and network		mode (i.e., WPA clients only)
	card driver	• Offers support for legacy WEP clients,
	(native support provided		but with increased security risk (i.e.,
	in Windows XP)		WEP authentication keys disabled)
		• Requires configured RADIUS server
		• 802.1x EAP type may require
			management of digital certificates for
			clients and server
WPA PSK	Requires WPA-enabled	• Provides good security in small
mode	system and network		networks
	card driver	• Requires manual management of
	(native support provided		pre-shared key
	in Windows XP)

Note: Although a WEP static key is not needed for WEP over 802.1x, WPA over 802.1x, and WPA PSK modes, you must enable WEP encryption through the web or CLI in order to enable all types of encryption in the access point.
