IDS for CAN: A Practical Intrusion Detection System for CAN Bus Security
IDS for CAN is developed – an Android application that functions as an intrusion detection system (IDS) for the CAN bus system, which will allow consumers to take charge of automotive security.
Abstract
Modern automobiles depend heavily on electronics, controlled by the vehicle's internal network. The controller area network (CAN bus) is the predominant protocol, known for its reliability but also its grievous lack of security. Unfortunately, security is expensive and automotive manufacturers seem disinclined to invest in CAN bus protection. Thus, consumers are left with few options to improve security. In this work, we develop IDS for CAN – an Android application that functions as an intrusion detection system (IDS) for the CAN bus system. In particular, it communicates with a standard ELM 327-type device, plugged into the diagnostic port that is mandatory in the United States and Europe. The application will detect suspicious traffic on the CAN bus and generate an alert to notify the user. In our evaluation, we investigate the performance with both datasets and real vehicles. The results indicate the practicability and the effectiveness of our proposed system. Our application will allow consumers to take charge of automotive security.
