Hackers Say Wireless Is Weak
Lock down your wireless network -- thats the message coming loud and clear now that the DefCon hacker convention has rolled through Las Vegas.
Jesse Krembs, president of The Hacker Foundation, who spoke at the show, warned that wireless is the weak under-belly of many businesses. I think that the main thing that people will be looking at is more wireless hacking, he says.
Krembs warns that this is as much about sloppiness as it is about technology. A lot of the problems with wireless security revolve around bad practice and poor cryptography issues."
He adds that planning is key when it comes to wireless deployments. If youre going to install mission-critical wireless, you need to do a site survey and think long term, he explains. Bluetooth deployments, in particular, need some serious thought. "Bluetooth and 802.11 in the same room is an issue. They operate in the same airspace, and if you have a really powerful Bluetooth device its going to drastically affect the 802.11 network.
Krembs also urged users to think twice about running Bluetooth all the time on their mobile phones. This, he notes, could open them up to "bluesnarfing," where hackers download information from the device.
