Abstract
A vehicle security system having controller area network buses, electronic control units connected to the controller area network buses, a vehicle security module connected to the controller area network buses, and an on board diagnostics connector connected to the vehicle security module. The vehicle security module may according to a policy discriminate between authorized and unauthorized signals that are input to the on board diagnostics connector. Authorized signals may be forwarded by the vehicle security module to the controller area network busses. Authorized signals may affect operation of one or more of the components of the vehicle via the electronic control units. Authorized signals may change the policy used by the vehicle security module. Unauthorized signals may be refused entry to the controller area network busses. The on board diagnostics connector may receive the signals from diagnostic instrumentation, control instrumentation, tracking instrumentation, a dongle, and so forth.
