Rogue employees setting up illegal wireless hotspots?

This week's WiFi security scare—that rogue employees could setting up unauthorized wireless hotspots at your workplace right now and you probably don't even know it!—comes to us courtesy of a bunch of security analysts at London's IT Security Summit who want to let you know your own workers, or maybe even scary hackers, are installing DIY WiFi access points in offices and that IT departments aren't even noticing. Yeah, you could simply bust out a WiFi detector or something, but as usual these warnings are more about scaring up business than anything else and AirDefense, one of the presenters at the summit, mentions that if you want to really make sure your office isn't riddled with illegal wireless access points you should probably buy their set of "wireless intrusion detection sensors" just to be on the safe side.
