A method of detecting an intermediary communication device in a communication path of a target communication device by inserting a sensor in the path, recording communication packets to and from the target communication device, recording times for the packets, identifying packets in a first interconnection layer, calculating a minimum latency time for the packets, identify packets in a second interconnection layer that is at a different communication processing level than that of the first interconnection layer, calculating a minimum latency time for the packets of the second interconnection layer, and determining that an intermediary communication device is present in the path if an absolute difference between the minimum latency times is above a user-definable threshold.
