Connected and Autonomous Vehicle

A Connected and Autonomous Vehicle (CAV) is a vehicle incorporating both connectivity and autonomous driving capabilities. Connectivity, often termed V2X (Vehicle-to-Everything), enables real-time data exchange with its environment. Autonomy is classified into six levels (L0-L5) by the SAE J3016 standard. In enterprise risk management, a CAV is treated as a complex cyber-physical system, where digital threats can cause physical harm. Traditional functional safety standards like ISO 26262 are insufficient. Therefore, the automotive industry relies on ISO/IEC 21434 for cybersecurity engineering and complies with regulations like UNECE R155. This regulation mandates a Cyber Security Management System (CSMS) to manage risks throughout the vehicle's lifecycle.

Enterprises apply CAV risk management by integrating the ISO/IEC 21434 framework into their development lifecycle. A key process is the Threat Analysis and Risk Assessment (TARA), implemented in three main steps. 1) Asset and Impact Analysis: Identify critical components (ECUs, sensors) and assess the potential impact of a compromise on safety and privacy. 2) Threat Scenario Modeling: Define potential attack vectors targeting these assets. 3) Risk Treatment and Verification: Determine risk levels, implement security controls like encryption and intrusion detection systems, and verify them through penetration testing. A leading Taiwanese Tier-1 supplier adopted this process, reducing its compliance review time with European OEMs by 30% and lowering the projected rate of critical security incidents by over 75%.

Taiwanese enterprises face three primary challenges in CAV security. 1) Complex Supply Chain Security: Ensuring end-to-end security is difficult due to varying cybersecurity maturity among suppliers. The solution is to enforce a supplier security framework based on ISO/IEC 21434, requiring audits and compliance evidence. 2) Regulatory Compliance Burden: Keeping pace with rapidly evolving regulations like UNECE R155 is resource-intensive. Mitigation involves creating a dedicated regulatory intelligence team and using compliance tools for automated gap analysis. 3) Cross-Disciplinary Talent Shortage: There is a significant lack of professionals skilled in both automotive engineering and cybersecurity. The strategy is to invest in training, partner with expert consultancies, and build a Product Security Incident Response Team (PSIRT).
