Imagine that wardrivers are casing your neighborhood. You've suppressed your SSID, you have WEP enabled and you've placed your wireless access point in a DMZ. You limit access to your wireless network by MAC address, block all most all traffic from the DMZ and require all your wireless clients to log into the real network via VPN in order to do anything. Sounds pretty good so far. The fact is that a hacker parked in your neighbor's driveway can still cause problems. How about making his life a little more difficult. What if when he turns on NetStumbler he sees 53,000 access points? Where would he start to look for yours?
