Work-in-Progress: Emerging E/E-Architectures as Enabler for Automotive Honeypots

The surge towards autonomous driving causes a growing need for software and connectivity inside the vehicle. This growth in complexity poses a substantial challenge to the security of vehicles as it expands the cyber attack surface. Moreover, to cope with computational demands, the automotive industry currently develops new in-vehicle architectures. In this context of emerging technologies and escalating complexity, ensuring cybersecurity is an increasingly demanding task. Honeypots are a well-established tool for threat intelligence and intrusion detection in traditional IT and the Internet of Things. In the automotive domain, however, honeypots have never found their way into practical application. In this work, we highlight how emerging in-vehicle architectures present opportunities for honeypot deployments inside the vehicle and threat landscape monitoring on the Internet. In contrast to existing research, we consider emerging in-vehicle architectures and how functional limitations from the automotive industry have prevented the widespread use of honeypots in the past.
