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 field settings.
