... how secure is this technology? What kinds of problems will IT staff encounter? One type of problem gaining national attention is called "war driving," in which a hacker can use a laptop computer to drive around and, like tuning in radio stations, can seek out personal information on wireless networks.

In the old days of computing, hackers used a technique called "war dialing." The computer's modem was set up to dial lists of phone numbers, hoping to reach another computer system's modem. Once a computer answered, a hacker would try to gain access to the network. This new laptop technique is called "war driving," and is actually much easier to do and easier to remain undetected. A person attempting to gain access to a network could easily sit in the parking lot across the street from the building itself and have access to their internal network.
