Enterprise Approaches to Detecting Rogue Wireless LANs

Enterprises are facing increasing risks of employees installing their own rogue wireless LANs to the enterprise network. Driven by the desire for mobility and fueled by the decreasing prices of wireless LAN hardware, these employees circumvent an enterprise’s investment in IT security by plugging a $60 wireless LAN access point into an Ethernet jack and connecting a $50 wireless access card to a laptop.

The end result is a wide-open entry point to the greater enterprise network. A rogue wireless LAN effectively extends an Ethernet connection to anyone inside and outside the building. Enterprises that have decided not to deploy wireless LANs must first set a policy banning employees from installing their own networks and then determine how to enforce that policy. This article introduces five approaches to detecting rogue wireless LANs and outlines the functionality and limitations of each.

So Many Nodes, So Little Security
(New York Times - December 12, 2002 - REGISTRATION REQUIRED)

than 14,000 business and personal networks - but also the apparent laxity of users about Wi-Fi's
built-in security.

Windows XP Spills the Beans on Wireless Access Points
(ExtremeTech - December 11, 2002)
Now that "war driving" -- searching for wireless LANs -- has become a popular pastime, many Internet service providers and businesses have begun to hide their Wi-Fi access points by preventing them from advertising an SSID (service set identifier). If this is done, only systems that know the access point's SSID can log onto the network.
