Security Options
You can choose the security type for your WLAN connection
from the following options:
None

WEP
: WEP (Wired Equivalent Privacy) is a wireless security
protocol for WLAN. WEP will encrypt data transmitted on the
WLAN.
WPA/WPA2 Personal
: uses a pre-shared key for
authentication. This pre-shared key is then dynamically sent
between the AP and clients. Each authorized computer is
given the same pass phrase.
WPA/WPA2 Enterprise
: this type includes all of the features
of WPA/WPA2 Personal plus support for 802.1x RADIUS
authentication.
802.1x
: authentication through a RADIUS server
RADIUS (Remote Authentication Dial-In User Service) is a widely deployed protocol that
enables companies to authenticate and authorize remote users
’ access to a system or
service from a central network server.
When you configure the remote access server for RADIUS authentication, the credentials of
the connection request are passed to the RADIUS server for authentication and authorization.
If the request is both authenticated and authorized, the RADIUS server sends an accept
message back to the remote access server and the connection attempt is accepted. If the
request is either not authenticated or not authorized, the RADIUS server sends a reject
message back to the remote access server and the connection attempt is rejected.
The principle of the Radius server is shown in the following pictures:
