More than half the wireless LAN access points located in a drive-by test have no encryption, raising the possibility that data could be monitored or captured. Of the 1,137 wireless nets that were found in Atlanta, Chicago, and San Francisco, 57% were not encrypted, according to AirDefense Inc. (www.airdefense.net), a company specializing in WLAN security. In Atlanta, only 8% of all traffic was encrypted, though in the other cities most nets with high volume that might typify business usage did have encryption to hide information from others. So, we won't be surprised if the Atlanta courts fill up with corporate espionage cases.
