Connected and Automated Vehicles

Connected and Automated Vehicles (CAVs) are vehicles featuring both connectivity (V2X - Vehicle-to-Everything communication) and automation (defined by SAE J3016 Levels 0-5). This integration transforms them into complex cyber-physical systems. Their expanded attack surface necessitates robust cybersecurity, governed by standards like ISO/SAE 21434, which defines a framework for cybersecurity engineering throughout the vehicle lifecycle. Furthermore, regulations such as UNECE R155 mandate the implementation of a certified Cyber Security Management System (CSMS) for vehicle type approval in signatory countries. In enterprise risk management, CAVs are critical assets requiring a dedicated risk assessment methodology like Threat Analysis and Risk Assessment (TARA) to identify and mitigate vulnerabilities from development to post-production, distinguishing them from vehicles with only basic telematics.

Practical application for CAV cybersecurity in enterprise risk management involves three key steps aligned with international standards: 1. **Establish a Cyber Security Management System (CSMS):** Implement an organizational framework compliant with UNECE R155, covering processes for risk management, development, production, and post-production phases to embed security into the corporate culture. 2. **Conduct Threat Analysis and Risk Assessment (TARA):** Systematically identify potential threats, attack vectors, and vulnerabilities in vehicle components and systems, following the methodology outlined in ISO/SAE 21434 to prioritize risks and define mitigation controls. 3. **Deploy a Vehicle Security Operations Center (VSOC):** Establish continuous monitoring capabilities to detect and respond to security incidents in the field, managing over-the-air software updates and vulnerability patching. Global OEMs implementing this approach achieve 100% compliance for type approval and reduce potential security incidents by over 40% through proactive risk mitigation.

Taiwanese enterprises, often acting as component suppliers in the automotive value chain, face specific challenges with CAV security: 1. **Lack of System-Level Perspective:** Suppliers are accustomed to meeting specifications rather than conducting holistic, vehicle-level Threat Analysis and Risk Assessment (TARA), leading to potential security gaps. 2. **Regulatory and Resource Gaps:** There is often a lag in understanding and implementing new international regulations like UNECE R155, coupled with limited resources and talent for a full CSMS implementation. 3. **Supply Chain Fragmentation:** Difficulty in cascading and verifying cybersecurity requirements up and down the supply chain creates breaks in security assurance. **Solutions:** The priority is to engage expert consultants for a regulatory gap analysis (2-month timeline). Subsequently, enterprises should standardize TARA processes and integrate them into supplier requirements. Finally, leveraging industry consortiums to promote shared security intelligence can strengthen the entire ecosystem.
