Lightweight Physical-based Intrusion Detection Systems for In-Vehicle Communication Networks Thema der Disputation:
Preventing or Detecting? Considerations and Challenges of Security Controls for Automotive Networks
Abstract:The increasing connectivity and software complexity of modern vehicles have significantly expanded their attack surface, as demonstrated by numerous researchers and real-world attacks over the last decade. While standards and regulations mandate the systematic consideration of cybersecurity, the question of which security controls to select for a protection of in-vehicle communication under automotive constraints cannot be answered unambiguously.
After a brief introduction to automotive security and the principle of defense in depth, this talk focuses on secure in-vehicle communication and corresponding security controls. Approaches for attack prevention, including cryptographic mechanisms such as SecOC, MACsec, and CANsec, are examined alongside approaches for an attack detection, with a focus on configuration-based and anomaly-based intrusion detection systems (IDSs). By systematically comparing these security controls, the talk will highlight their respective strengths and limitations, emphasizing the challenge in selecting a suitable security control.
The second part of the talk addresses physical-based IDSs, a specific type of anomaly-based approaches. By leveraging unique physical characteristics of electronic control units (ECUs) during communication, these systems are able to assess message authenticity. Having developed different types of physical-based IDSs, their functional principles and performance are presented and compared to the previously discussed security controls, allowing an assessment of their viability for protecting in-vehicle communication in current and future vehicles.
