INVESTIGATION ON CYBER-ATTACKS AGAINST IN-VEHICLE NETWORK

The adaptation of modern technologies in vehicles has revolutionized the way we commute both in private and commercial vehicles. The new era of connected vehicle eco-system is likely to improve the ease of driving and to reduce accidents. This is possible only with a complex network connectivity, which has caused a massive rise of cyber-attacks in the past decade. The nature of wired and wireless communication makes connected vehicles vulnerable to cyber threats, a serious security problem for both peoples on-board and on-road. Controlled Area Network (CAN), the de-facto protocol used for in-vehicle communication, suffers from security flaws such as message encryption and sender authentication, which are important to protect the network from cyber-attacks. This paper makes an investigation on different real time cyber-attacks took place in the past ten years to study and understand vulnerabilities that can make a vehicle network fragile. Suggestions are proposed to secure the in-vehicle communication bus and to develop suitable countermeasures. Future forecast has been discussed to highlight the seriousness of the cyber-attack towards vehicle ecosystem.
