A method for detecting spoofing by wireless access devices. In some embodiments, spoofing can be detected based on locations for a wireless access device having an identifier at first and second times. The locations are compared to determine whether the wireless access device could access the particular network at the locations in the time period between the first and second times. In several embodiments, spoofing can be detected by tracking the activity of wireless access devices and identifying events that that are prohibited by one or more policy elements of the particular network.

Spoofing detection

Spoofing detection for a wireless system

Methods are described herein useful for detecting spoofing by wireless access devices. In some embodiments, spoofing can be detected based on locations for a wireless access device having an identifier at first and second times. The locations are compared to determine whether the wireless access device could access the particular network at the locations in the time period between the first and second times. In several embodiments, spoofing can be detected by tracking the activity of wireless access devices and identifying events that that are prohibited by one or more policy elements of the particular network.

A wireless access device in a wireless network, whether a known or unknown entity, can be located using a geolocation system according to the present invention. A signal strength is determined by a wireless intrusion detection system (WIDS) node in a wireless network for each wireless access device that it detects. Based on the signal strength, an approximate distance from the node is determined, which, in one embodiment corresponds to a radius of a circle around the node. To account for error, an approximation band of the circle is calculated that will allow a user to determine the approximate location of the device within the wireless network.

Method and system for locating a wireless access device in a wireless network

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.
