Abstract:
In one implementation, a method for providing security on controllers includes detecting, by a given controller, an attempted security attack on the given controller; in response to detecting the attempted attack, entering a safe mode of operation for the given controller in which at least one process performed by the given controller is restricted such that the at least one process is performed only when a current context of the controller matches a permitted context that is associated with the given controller; in response to detecting the attempted attack, transmitting a safe mode alert to one or more other controllers; and for at least one of the one or more other controllers, in response to receiving the safe mode alert, entering a safe mode of operation for the other controller.

Claim (Index 1):
A system for data communication for the operation of an automobile, the system comprising:\n the automobile, the automobile comprising:\n a first electronic control unit (ECU) being directly accessible to external networks that are outside of the automobile; \n a second ECU that is not directly accessible to the external networks that are outside of the automobile; \n a control area network (CAN) bus that communicably couples the first ECU and the second ECU such that the first ECU and the second ECU can pass data communications within the automobile; \n wherein the first ECU is configured to:\n operation either in a normal mode or in a first safe-mode, wherein in the first safe-mode comprises stricter security policies than the normal mode; \n while operating in the normal mode, detect an attempted attack on the automobile; \n responsive to detecting the attempted attack on the automobile, determine that the detected attempted attack is indicative of attempted malicious execution by malware; \n responsive to determining that that the detected attempted attack is indicative of attempted malicious execution by malware, change modes from the normal mode to the first safe-mode; \n responsive to determining that that the detected attempted attack is indicative of attempted malicious execution by malware, transmitting over the CAN bus a safe-mode alert; \n wherein the second ECU is configured to:\n operate in either the normal mode or a second safe-mode, wherein in the second safe-mode comprises stricter security policies than the normal mode and wherein the second safe-mode comprises different security policies than the first-safe mode; \n while operating in the normal mode, receive the safe-mode alert from the first ECU over the CAN bus; and \n responsive to receiving the safe-mode alert, change modes from the normal mode to the safe mode.
