Figure 4.20 Using Signal Strength to Find Wireless Networks
To enhance their ability to locate the positions of a wireless network, an
attacker can use directional antennas to focus the wireless interface in a specific
direction.An excellent source for wireless information, including information on
the design of directional antennas, is the Bay Area Wireless Users Group
(www.bawug.org).
NOTE
Keep in mind that the most popular wireless network security scanning
tools are Wireshark, NetStumbler, AiroPeek, and Kismet. This will help
you analyze wireless networks in the field. Each tool has its benefits, so
you may want to try them all if you have access to them.
