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.
