4.5.3.4 WIRELESS – Security - WPA
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 including 802.1X, EAP and RADIUS are used for strong authentication. Like WEP, keys can still be
entered manually (preshared keys); however, using a RADIUS authentication server provides automatic key
generation and enterprise-wide authentication. Figure below illustrates the default setting of the WPA (Wi-Fi
Protected Access) Wireless Security screen.
Note:
Not all wireless adapters support WPA. Furthermore, client software is required on the client.
Group Key Interval:
Type a numeric value (In seconds) of the time lapse in changing the key in
the
“Group Key Interval”
box.
802.1x:
When selected, the WPA stations authenticate with the RADIUS server using EAP-TLS
(Extensible Authentication Protocol - Transport Layer Security) over 802.1x.
Port:
The RADUIS server's port.
Secret:
The secret that the AP shares with the RADIUS server.
PSK String:
Pre-Shared Key String. When selected, the WPA stations do not authenticate with
the RADIUS server using EAP-TLS. Instead they share a pre-shared secret with the AP (ASCII
format). The PSK string needs to be entered in the first time configuration with each station.
