The Livermore lab, which conducts nuclear-weapons research among other things, has banned all wireless networks from its campus. Its sister lab, the Los Alamos National Lab in New Mexico, does not allow them in high-security areas and is considering a campus ban.
M.D. Anderson Cancer Center in Houston canceled a Wi-Fi pilot program last fall because executives worried that patient data might be intercepted. The center plans to test a more secure version of Wi-Fi this summer.
Aeronautical Radio, which provides communications services to airlines and the government, is encouraging customers to move away from Wi-Fi-type systems because of the security risk. The company hopes to replace a wireless bag-matching network it operates for San Francisco International Airport with a safer system. "Using (Wi-Fi) for mission-critical operations is extremely dangerous," says company Vice President Joe Weiss.
The U.S. Department of Transportation in December started assessing security risks of new technologies, including Wi-Fi, in airports. The concern: Hackers could get into wireless networks of airlines and alter flight, baggage and passenger data. Airlines, including American and Southwest, say they have safeguarded their systems. They won't elaborate, citing security concerns.
Still, use of Wi-Fi is likely to spread, experts say, especially in home networks. That's because it's an ideal way to wirelessly link users to the Internet and to send data between consumer electronics and personal computers.
