4-2 Wireless Configuration
Implement Appropriate Wireless Security
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The DG824M wireless gateway provides highly effective security
features which are covered in detail in this chapter. Deploy the security features appropriate to
your needs.

Restricting access by MAC address filtering adds an obstacle against unwanted access to your
network, but the data broadcast over the wireless link is fully exposed. To block a determined
eavesdropper, you should use one of the data encryption options of the firewall. Wired Equivalent
Privacy (WEP) data encryption provides data security.
Note:
Indoors, computers can connect over 802.11b wireless networks at a
maximum range of up to 300 feet.
Such distances can allow for others outside of your
immediate area to access your network.
1) Open System: Easy but no security
2) MAC Access List: No data security
3) WEP: Security but some performance impact
