Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3

Implementing Appropriate Wireless Security
Unlike wired network data, your wireless data transmissions can be received well beyond your
walls by anyone with a compatible adapter. For this reason, use the security features of your
wireless equipment. The WGT624 v3 wireless router provides highly effective security features
which are covered in detail in this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of you wireless network.
• Restrict Access Based on MAC (Media Access Control) address. You can restrict access to
only trusted computers o that unknown computers cannot wirelessly connect to the
WGT624 v3. MAC address filtering adds an obstacle against unwanted access to your
network, but the data broadcast over the wireless link is fully exposed.
• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network ‘discovery’ feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.
Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges
of up to 500 feet. Such distances can allow for others outside of your immediate
area to access your network.
