More functions are getting packed into our wireless devices all the time, which makes the devices ever more useful and important to us. Of course that also means that protecting the devices and the communications between them and the servers with which they interact becomes more important too. I was reminded of that by a couple of reports I read recently.

In the Security UPDATE "In Focus" commentary "What to Expect in 2008," January 9, 2008, Mark Edwards cites wireless networks as being ripe for widespread attacks because of the combination of many wireless networks being open for anyone to use and the existence of vulnerabilities in wireless routers.

AirMagnet, a provider of wireless network performance and security solutions, said in a set of wireless predictions for 2008 that "Over the next year, enterprises will understand that WEP is obsolete—better measures must be taken to ensure effective wireless network security."

If you've taken steps to secure your wireless network, that’s great. But if you're still counting on Wired Equivalent Privacy (WEP) or you think your network might have other weaknesses, you can find help for moving to Wi-Fi Protected Access (WPA) and for taking other wireless network security measures in the articles listed below.
