Abstract
A system and method for detecting unauthorized use of a wireless local area network is described, wherein the network includes mobile units that communicate with at least one access point. First network traffic data is accumulated at a mobile unit. Second network traffic data is accumulated at an access point. The first and second traffic data is communicated to a computer and is correlated by the computer to identify non-correlated traffic data. An alarm condition is signaled when the non-correlated traffic data exceeds a threshold.
Claims21
A method for detecting unauthorized use of a wireless local area network having at least one mobile unit that communicates with at least one access point, comprising:
- accumulating first network traffic data at a mobile unit;
- accumulating second network traffic data at an access point;
- communicating said first and second traffic data to a computer;
- and
- correlating said first and second traffic data in said computer to identify non-correlated traffic data indicative of unauthorized use of the wireless local network and signaling an alarm condition when said non-correlated traffic data exceeds a threshold portion of said traffic data.
A method for detecting unauthorized use of a wireless local area network having at least two mobile units that communicate with at least one access point, comprising:
- accumulating first network traffic data at a first mobile unit;
- accumulating second network traffic data at a second mobile unit;
- communicating said first and second traffic data to a computer;
- and
- correlating said first and second traffic data in said computer to identify non-correlated traffic data indicative of unauthorized use of the wireless local network and signaling an alarm condition when said non-correlated traffic data exceeds a threshold portion of said traffic data.
A system for detecting unauthorized use of a wireless local area network, comprising:
- at least one mobile unit;
- at least one access point;
- and
- at least one server computer,
- wherein first network traffic data is accumulated by said at least one mobile unit, second network traffic data is accumulated by said at least one access point, said first and second network traffic data are communicated to said at least one server computer, said first and second network traffic data are correlated by said at least one server computer to identify non-correlated traffic data indicative of unauthorized use of the wireless local area network, and an alarm condition is signaled when said non-correlated traffic data exceeds a threshold.
