Modern vehicles are increasingly equipped with highly automated control systems both for driving and for comfort. An integral part of these systems are the communication channels that allow the on-board to interact with passenger devices (e.g. tablets), ITS systems (e.g. road-side units), and other vehicles. advances have significantly enlarged the attack surface and we already have numerous instances of penetration of vehicular networks both from inside the vehicle and from the outside. Traditional for detecting and responding to such attacks are ill-suited to the vehicular domain mainly due to fact that the entire process of dealing with an attack must be handled automatically and in a way that does affect safety or severely impacts the continued availability of the vehicle or its key systems. Once a security is suspected, the system must evaluate the circumstances in order to determine whether the threat is (and not a false positive) and select the optimal response through the use of an Intrusion Response System(IRS). Although IRSs have been adopted in other domains, there is a lack of such systems in the vehicular. In this paper, we investigate the challenges and requirements for integrating such a mechanism inside a. In addition, we present an Intrusion Response System based on the Red-Zone principle which meets identified requirements. Finally, we discuss the integration of IRS through the vehicle system development the different aspects which support such a process.
