Rogue access point

From Wikipedia, the free encyclopedia

A rogue access point is a wireless access point that has been installed on a secure company network without explicit authorization from a local network management. Rogue access points can pose a security threat to large organizations with many employees, because anyone with access to the premises can ignorantly or maliciously install an inexpensive wireless router that can potentially allow access to a secure network to unauthorized parties. To prevent the installation of rogue access points, large organizations sometimes even install wireless intrusion detection systems to monitor the radio spectrum for unauthorized access points.
