1. A method for providing vehicle intrusion detection for a vehicle comprising a wireless wide area network interface to access a wireless wide area network, a wireless local area network interface operable to provide a wireless local area network mobile with said vehicle, a vehicle network bus and a plurality of electronic control units each electronic control unit comprising a separate processor, a separate physical memory accessible by said separate processor, and a separate interface to said vehicle network bus, each of said electronic control units being coupled to said vehicle network bus, said method comprising:

  • providing said vehicle with a predetermined one electronic control unit of said plurality of electronic control units;

    said predetermined electronic control unit operable to route data between one or more mobile devices located in said vehicle coupled to said wireless local area network and said wireless wide area network,operating said predetermined one electronic control unit to monitor data on said vehicle network bus;

    storing an intrusion detection program in said separate physical memory of said predetermined one electronic control unit, said intrusion detection program executable only by said separate processor of said predetermined one electronic control unit to detect said one or more types of anomalies that are indicative of an electronic intrusion;

    isolating said intrusion detection program to insure the integrity of said intrusion detection program, said isolating comprising utilizing one or more memory isolation approaches to isolate said intrusion detection program from all other programs in said vehicle;

    operating said separate processor of said predetermined one electronic control unit to execute said intrusion detection program to detect one or more types of anomalies indicative of an electronic intrusion in said monitored data;

    said one or more anomalies indicative of an electronic intrusion comprise re-flashing of an electronic control unit memory and predetermined radio frequency hub activity in said vehicle of a type that comprise attempts to determine a predetermined code assigned to said vehicle; and

    receiving at least one of calibration information and update information for said intrusion detection program via a selected one of said wireless wide area network interface and said wireless local area network interface; and

    operating said predetermined one electronic control unit to generate an alert of an electronic intrusion upon detection of said one or more of anomalies indicative of an electronic intrusion.
