摘要

In a network security system, clients search for neighbor access points (APs) in order to establish wireless connections to a LAN. As a result of the search, each of the clients dispatches a list of access points obtained to a controller. The controller detects non-registered access points by comparing a list of previously registered access points with the lists dispatched by the clients.
