Other dangers
Certainly there are other mobile computing dangers to watch out for. The increased popularity of 802.11b wireless networks--and the availability of add-on cards for Palm, Handspring, and Pocket PC PDAs--means that any security concerns for 802.11b networks now concern enterprise handheld users.
There is some discussion concerning the implementation of Wired Equivalent Privacy (WEP) and whether it is open to compromise; also there is the possibility that PDA users who hook in on public WiFi connections could be vulnerable to attack.
Nachenberg sees that as a future possibility, if appropriate safeguards aren't instituted. "You'll be walking down the street," he says, "and you may get a virus just by walking next to somebody who has an infected device, depending on the susceptibility of these machines."
Right now, that threat is only speculation, something to look at in the next few years. However, companies that are issuing PDAs to their employees may want to take actions today that will prevent the theft of sensitive information tomorrow.
