Wireless networks are exploding in popularity. This boom is no big surprise, in light of how convenient they are to set up and use. You might think that only small companies and home users depend on wireless, but you'd be wrong-major enterprises, including Microsoft, have plumbed their corporate facilities with wireless access points (APs) so that corporate users can get seamless access to their networks from conference rooms, hallways, lunchrooms, and other formerly unwired locations. This flexibility and freedom can comes at a cost: you have to buy wireless hardware, configure it properly, and set it up in physical locations that allow good signal coverage of the desired area. Apart from those mundane issues, though, wireless LANs (WLANs) have some potential security problems that you should know about. |
