3) Research of New Cyberattack Techniques and Countermeasure Technologies

Abstract

As connected cars and automated driving systems develop and spread, a lot of information of advanced maps and the vehicles, people, and infrastructure facilities mapped onto them is transmitted to vehicles via external networks. This situation causes cybersecurity issues. Furthermore, since the introduction of UN-R155/R156 to the safety standards for road vehicles—agreed-upon regulations for cybersecurity and software updates—it is also necessary to take countermeasures against cyberattacks from a legal perspective. To solve these issues, this study focused on intrusion detection systems (IDS) as a new countermeasure technology against cyberattacks after shipment, and developed IDS evaluation guidelines to serve as a baseline for evaluation and testing when introducing IDS. During the current fiscal year, we are studying methods of collecting and accumulating threat information on connected cars and conducting collection experiments using methods such as honeypots, seeking to create a mechanism to support an initial response when an incident actually occurs.
