Abstract: An in-vehicle communication network of a vehicle is monitored. An illicit signal is detected on the in-vehicle communication network. Whether the illicit signal satisfies a threshold severity condition is determined. A denial of service (DoS) operation with respect to at least part of the in-vehicle communication network is performed responsive to determining that the illicit signal satisfies the threshold severity condition.

Abstract: An illicit signal is detected on an in-vehicle communication network of an autonomous vehicle. A severity level corresponding to the illicit signal is identified, among multiple severity levels, based on one or more characteristics associated with the illicit signal. The severity level is indicative of a level of adverse impact on safety related to an autonomous vehicle environment. The adverse impact is to be caused by the autonomous vehicle when the autonomous vehicle is compromised by the illicit signal. A security operation is selected from multiple security operations based on the identified severity level. The security operation is performed to mitigate the adverse impact on safety related to the autonomous vehicle environment.
