The Controller Area Network (CAN) in cars is critical to their safety and performance and is now regarded as being vulnerable to cyberattack. Recent studies have looked at securing the CAN and at intrusion detection methods so that attacks can be quickly identified. The CAN has qualities that distinguish it from other computer networks, while the nature of car production and usage also provide challenges. Thus attack detection methods employed for other networks lack appropriateness for the CAN. This paper surveys the methods that have been investigated for CAN intrusion detection, and considers their implications in terms of practicability and requirements. Consequent developments that will be needed for implementation and research are suggested.
