Abstract
Logic may reduce the latency and increase the confidence in message time series (MTS) intrusion detection systems (IDSs). Logic may capture traffic on an in-vehicle network bus during a first traffic window. Logic may filter the traffic within the first traffic window to determine more than one observation window, wherein the more than observation window comprises at least a first observation window and a second observation window. Logic may evaluate the more than one observation window to determine a first output based on a first observation window and a second output based on a second observation window, the first and second outputs to indicate if an intrusion is detected. Logic may determine, based on a combination of the outputs, that the traffic during the first traffic window comprises an intrusion. Logic may output an indication of the intrusion.
