WEP 128 Deployment Considerations
Before defining a WEP 128 supported configuration on a WLAN, refer to the following deployment guidelines to ensure the
configuration is optimally effective:
• It is recommended that additional layers of security (beyond WEP) be enabled to minimize the likelihood of data loss and
security breaches. WEP enabled WLANs should be mapped to an isolated VLAN with Firewall policies restricting access to
hosts and suspicious network applications.
• WEP enabled WLANs should only be permitted access to resources required by legacy devices.
• If WEP support is needed for WLAN legacy device support, 802.1X EAP authentication should be also configured in order
for the WLAN to provide authentication and dynamic key derivation and rotation
6.2.0.4 Keyguard
Configuring WLAN Security Settings
Keyguard is a form of WEP, and could be all a small business needs for the simple encryption of wireless data.
KeyGuard is an enhancement to the WEP encryption method, and was developed before the finalization of WPA-TKIP. The
Keyguard encryption implementation is based on the IEEE Wi-Fi standard, 802.11i.
To configure Keyguard encryption on a WLAN:
1. Select
Configuration
>
Wireless
>
Wireless LAN Policy
to display available WLANs.
2. Select the
Add
button to create an additional WLAN or select
Edit
to modify the properties of an WLAN.
3. Select
Security
.
4. Select the
Keyguard
check box from within the
Select Encryption
field.
The screen populates with the parameters required to define a KeyGuard configuration for the WLAN.
