Recent advancements towards autonomous heavy duty vehicles are directly associated with increased interconnectivity and software driven features. Consequently, rise of this technological trend is bringing forth safety and cybersecurity challenges in form of new threats, hazards and vulnerabilities. As per the recent UN vehicle regulation 155, several risk-based security models and assessment frameworks have been proposed to counter the growing cybersecurity issues, however they lack compliance with the latest requirements of ISO/SAE 21434 standard. This paper proposes an automated Threat Assessment & Risk Analysis (TARA) framework aligned with the standard requirements. The proposed framework is tailored specifically for heavy-duty vehicular networks and it demonstrates its effectiveness on a case study.
