9.2.2 WLAN Add/Edit: WEP Security

WEP provides a mechanism for encrypting data using encryption keys. Both the

ZyWALL and the wireless stations must use the same WEP key to encrypt and

decrypt data. Your ZyWALL allows you to configure up to four 64-bit or 128-bit

WEP keys, but only one key can be used at any one time.

Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using

widely-available software. It is strongly recommended that you use a more

effective security mechanism. Use the strongest security mechanism that all the

wireless devices in your network support. For example, use WPA-PSK or

WPA2-PSK or WPA or WPA2 if your wireless devices support it. If your wireless

devices support nothing stronger than WEP, use the highest encryption level

To configure and enable WEP encryption, click the Add (or Edit) icon next to a

wireless interface in the Device Operation > Device Configuration > Network

> Interface > WLAN > General to open the WLAN Edit screen. Select WEP as

the Security Type. The following screen shows the WEP security fields.
