1. A method of operating a predetermined electronic control unit disposed in 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 one or more additional electronic control units each comprising a separate processor and a separate dedicated memory and each said additional electronic unit coupled to said vehicle network bus, said predetermined electronic control unit comprising a predetermined unit separate processor, a predetermined unit separate dedicated memory, and a predetermined unit interface to said vehicle network bus, 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, said method comprising:
providing said predetermined electronic control unit with an intrusion detection program to detect electronic intrusions;
storing said intrusion detection program in said predetermined unit separate dedicated memory;
isolating said intrusion detection program to insure the integrity of said intrusion detection program,
utilizing one or more memory isolation approaches to isolate said intrusion detection program from said any other programs in said vehicle including all said any other programs stored in said predetermined unit separate dedicated memory;
executing said intrusion detection program to monitor data on said vehicle network bus;
executing said intrusion detection program to detect one or more anomalies indicative of 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
generating an alert upon detection of said one or more of anomalies indicative of electronic intrusion.
