Security Type Description Security Features Enabled
No Security This is the least secure option. You should use this option
only for SSIDs used in a public space and assign it to a
VLAN that restricts access to your network.
None.
Static WEP Key This option is more secure than no security. However,
static WEP keys are vulnerable to attack. If you
configure this setting, you should consider limiting
association to the wireless device based on MAC
address. See Cipher Suites and WEP at Cisco.com for
configuration procedures,

.
Or
If your network does not have a RADIUS server,
consider using an access point as a local authentication
server.
See Using the Access Point as a Local Authenticator at
Cisco.com for instructions,

Mandatory WEP. Client devices
cannot associate using this SSID
without a WEP key that matches the
wireless device key.
