WEP 64 Deployment Considerations
Before defining a WEP 64 supported configuration on a WLAN, refer to the following deployment guidelines to ensure
the configuration is optimally effective:
• Motorola Solutions Solutions recommends additional layers of security (beyond WEP 64) 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.

6.1.2.8 WEP 128 and KeyGuard

Configuring WLAN Security
Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi -Fi) standard. WEP is
designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN.
KeyGuard is a Motorola Solutions encryption option used with legacy clients capable of supporting it. It closely
resembled WEP 128 in key structure.
WEP can be used with open, shared, MAC and 802.1 X EAP authentications. WEP is optimal for WLANs supporting
legacy deployments when also used with 802.1X EAP authentication to provide user and device authentication and
dynamic WEP key derivation and periodic key rotation. 802.1X provides authentication for devices and also reduces
the risk of a single WEP key being deciphered. If 802.1X support is not available on the legacy device, MAC
authentication should be enabled to provide device level authentication.
WEP 128 and KeyGuard use a 104 bit key which is concatenated with a 24-bit initialization vector (IV) to form the RC4
traffic key. WEP may be all a small-business user needs for the simple encryption of wireless data. However, networks
that require more security are at risk from a WEP flaw. WEP is only recommended if there are client devices that are
incapable of using higher forms of security. The existing 802.11 standard alone offers administrators no effective
method to update keys.
WEP 128 or Keyguard provide a more robust encryption algorithm than WEP 64 by requiring a longer key length and
pass key. Thus, making it harder to hack through the replication of WEP keys.
