Automotive Cybersecurity Engineering with Modeling Support

Rapid advances of connected and autonomous vehicle technology have led to an increase in cyber-attacks. This in turn has driven the development of the ISO 21434 standard aimed at supporting the management of cybersecurity risks in the automotive industry. There is, however, a disconnect between the standard and the currently applied model-based development approaches that are increasingly applied for systems and software development. In this paper, we present tool support created for model-based automotive cybersecurity engineering. This tool is built upon the existing automotive systems development language, EAST-ADL, with extensions to address security in accordance with the ISO 21434 standard covering modeling support, calculation of security-related metrics such as impact, risk, and attack feasibility, and generation of ISO 21434 compliant security threat reports. Meeting the requirements of cybersecurity engineeering according to ISO 21434 are demonstrated with two examples.
