1. A method, comprising:
detecting an illicit signal on an in-vehicle communication network of an autonomous vehicle;
identifying, among a plurality of severity levels and at the autonomous vehicle, a severity level corresponding to the illicit signal based on one or more characteristics associated with the illicit signal, the severity level indicative of a level of potential adverse impact on safety related to an autonomous vehicle environment, the potential adverse impact to be caused by the autonomous vehicle when the autonomous vehicle is compromised by the illicit signal;
identifying, among a plurality of groups of security operations, a first group of security operations corresponding to the identified severity level;
selecting, at the autonomous vehicle, a security operation from the first group of security operations based on a current vehicle state of the autonomous vehicle; and
performing, by a processing device, the security operation to mitigate the potential adverse impact on safety related to the autonomous vehicle environment.
