WPA (Wi-Fi Protected Access) is a security protocol for Wireless Local Area Networks

(WLAN). WPA uses a sophisticated key hierarchy that generates new encryption

keys each time a mobile device establishes itself with an access point. Protocols in-

cluding 802.1X, EAP and RADIUS are used for strong authentication. Like WEP, keys

can still be entered manually (preshared keys); however, using a RADIUS authenti-

cation server provides automatic key generation and enterprise-wide authentication.

The screen below illustrates the default setting of the WPA (Wi-Fi Protected Access)

Wireless Security screen.

Following is a description of the WPA Security eld settings.
