A New Perspective in Automotive Cybersecurity: Principles and Practices of Security Chain Strategy

Huiru Ma, Eberspächer Gruppe GmbH & Co. KG

This paper introduces a Security Chain strategy for enhancing cybersecurity in Vehicle Control ECUs, pivotal in today`s automotive industry. With escalating cyber threats and stringent global regulations like UNECE155 and China`s automotive cybersecurity standards, Vehicle Control ECUs face significant security challenges. This paper addresses the conflict between the necessity for robust cybersecurity measures and their associated high costs and complexity. The proposed Security Chain strategy offers a holistic approach to manage cybersecurity risks effectively and economically. Key components of this strategy include: 1.Theoretical Foundation of Security Chain: Establishing a comprehensive framework for identifying and managing cybersecurity risks in ECUs. 2.Identification of Key Security Features: Analyzing and categorizing crucial cybersecurity features in Vehicle Control ECUs. 3.Scoring System for Security Features: Implementing a scoring mechanism to prioritize security features based on their significance and urgency. 4.Integration with Existing Standards: Harmonizing the Security Chain strategy with current cybersecurity measures, national laws, and OEM specifications. The solution not only addresses current cybersecurity challenges but also provides a new perspective for thinking about automotive cybersecurity. This approach ensures Vehicle Control ECUs are resilient against diverse cyber threats while adhering to industry standards and regulations.
