Method and system for packet acquisition, analysis and intrusion detection in field area networks

摘要

A packet intercept system includes probes along the field area network. A portion of the probes are mobile probes configured to receive and process a global positioning system signal. Intercepting by the mobile probes includes implementing a global positioning tag in each packet in the traffic data stream intercepted by the mobile probes, the global positioning tag includes a timestamp and global positioning system coordinates, derived from the global position system signal. The packet intercept system backhauls the traffic data stream to an additional network that is distinct from the field area network. Processors on the additional network obtain the traffic data stream and process the stream into a live traffic data stream by ordering each packet intercepted by the mobile probes in the processed live traffic data stream, based on the timestamp. The processors analyze the processed live traffic data stream.
