Configuring SSID Profiles

Security Mode	Description
WEP	Wired Equivalent Privacy (WEP) is a data encryption
	protocol for 802.11 wireless networks. All wireless
	stations and SSIDs on the network are configured with
	a static 64-bit or 128-bit Shared Key for data
	encryption. The higher the bit for data encryption, the
	more secure for your network.
	WEP encryption is an older encryption method that is
	not considered to be secure and can easily be broken.
	Choose this option only if you need to allow access to
	devices that do not support WPA or WPA2.
WPA	Wi-Fi Protected Access (WPA) provides better
	security than WEP because it uses dynamic key
	encryption. This standard was implemented as an
	intermediate measure to replace WEP, pending final
	completion of the 802.11i standard for WPA2.
	The security appliance supports the following WPA
	security modes. Choose one of them if you need to
	allow access to devices that do not support WPA2.
	• WPA-Personal:Supports TKIP (Temporal Key
	Integrity Protocol) or AES (Advanced Encryption
	System) encryption mechanisms for data
	encryption (default is TKIP). TKIP uses dynamic
	keys and incorporates Message Integrity Code
	(MIC) to provide protection against hackers. AES
	uses symmetric 128-bit block data encryption.
	• WPA-Enterprise:Uses WPA with RADIUS
	authentication. This mode supports TKIP and
	AES encryption mechanisms (default is TKIP)
	and requires the use of a RADIUS server to
	authenticate users.
