Wireless Security Options

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 Wireless AP 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 your wireless network:

• Restrict Access Based on MAC Address. You can restrict access to only trusted PCs so that

unknown PCs cannot wirelessly connect to the WG602v3. MAC address filtering adds an

obstacle against unwanted access to your network, but the data broadcast over the wireless link

is fully exposed (see

“Restricting Wireless Access by MAC Address” on page 2-19).

• 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.

• Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP

Shared Key authentication and WEP data encryption will block an eavesdropper but because

the keys are static, a determined snoop can learn the keys in less than a day of eavesdropping

(see

“Configuring WEP Wireless Security” on page 2-16).
