An Overview of Security in Connected and Autonomous Vehicles

As the enabling technologies for connected and autonomous vehicles (CAV) continue to advance and these modes of transportation become more commonplace, there is a reasonable expectation that the systems will increasingly become targets for bad actors. The complexity and inter-connectedness of these devices offer myriad opportunities for security compromise, potentially resulting in unsafe operation or leakage of confidential information about the user. This paper conducts a brief review of the current state of CAVs with regard to security and privacy. We present a taxonomy for classification of these threats and use it to identify and enumerate existing threats in this space.
