ABSTRACT:
Characteristics about one or more wireless access devices in a wireless network, whether known or unknown entities, can be determined using a system and method according to the present invention. An observation is made of the activity over a Wireless Area Network (WLAN). Based on this activity, changes in state of wireless access devices within the WLAN can be observed and monitored. These changes in state could be indicative of normal operation of the WLAN, or they may indicate the presence of an unauthorized user. In the latter case, an alert can be sent so that appropriate action may be taken. Additionally, ad hoc networks can be detected that may be connected to a wireless access point.
