Wi-Fi Protected Access (WPA) was introduced as an interim solution for the
WPA E
NTERPRISE
vulnerability of WEP pending the adoption of a more robust wireless
M
ODE
security standard. WPA2 includes the complete wireless security standard,
but also offers backward compatibility with WPA. Both WPA and WPA2
provide an "enterprise" and "personal" mode of operation.
For enterprise deployment, WPA and WPA2 use IEEE 802.1X for user
authentication and require a RADIUS authentication server to be
configured on the wired network. Data encryption keys are automatically
generated and distributed to all clients connected to the network.
Figure 47: Security Mode - WPA
The following items are displayed in this section on this page:
Security Mode — Configures the WPA and WPA2 security modes used by
clients. When using WPA or WPA2, be sure there is a RADIUS server in the
connected wired network, and that the RADIUS settings are configured.

"IEEE 802.1X and RADIUS" on page 81
WPA — Clients using WPA with an 802.1X authentication method are
accepted for authentication. The default data encryption type for WPA
is TKIP.
WPA2 — Clients using WPA2 with an 802.1X authentication method
are accepted for authentication. The default data encryption type for
WPA is AES.
