Express Security Types
There are four security types you can assign to an SSID:
•
No security—The least secure option. Use this option only for SSIDs
used in a public space, and assign it to a VLAN that restricts access to
your network.
•
Static WEP Key—More secure than no security. Static WEP keys are
vulnerable to attack. There are two different lengths for WEP keys:
40-bit and 128-bit (hexadecimal or ASCII characters). Cisco access
points use hexadecimal characters. Client adapters can use either,
depending on how the vendor chooses to configure them.
•
EAP Authentication—Enables 802.1x authentication. Requires an IP
address and shared secret from an authentication server on your network
(server authentication port 1645). You do not need to enter a WEP key.
•
WPA—Wi-Fi Protected Access (WPA) permits wireless access to users
authenticated against a database through the services of an
authentication server and encrypts their IP traffic with stronger
algorithms than those used in WEP. As with EAP authentication, you
must enter the IP address and shared secret for an authentication server
on your network (server authentication port 1645).
