Vehicle Cybersecurity

Vehicle cybersecurity is the engineering practice of protecting road vehicles, their electronic systems, and communication networks from cyber threats. With the rise of connected cars (V2X) and autonomous driving, vehicles have become complex computing platforms, expanding their attack surface. The core international standard is **ISO/SAE 21434:2021**, which specifies requirements for a Cybersecurity Management System (CSMS) throughout the vehicle lifecycle. This is complemented by the **UNECE WP.29 R155** regulation, which mandates a certified CSMS for vehicle type approval in over 50 countries. Unlike traditional IT security, vehicle cybersecurity places a strong emphasis on functional safety, as a successful cyberattack could compromise critical systems like braking or steering, leading to severe physical harm.

In enterprise risk management, vehicle cybersecurity is applied by integrating a structured Cybersecurity Management System (CSMS) into core processes, guided by **ISO/SAE 21434**. Key steps include: 1) **Establishing Governance**: Defining roles, responsibilities, and policies. 2) **Performing TARA**: Conducting Threat Analysis and Risk Assessment to identify vulnerabilities and define mitigation measures. 3) **Managing Supply Chain Risk**: Extending cybersecurity requirements to suppliers. Measurable outcomes include achieving 100% compliance with **UN R155** for market access, reducing critical vulnerabilities, and passing third-party audits, thereby minimizing recall risks and protecting brand reputation.

Taiwan enterprises, particularly SMEs in the automotive supply chain, face several challenges: 1) **Talent and Knowledge Gap**: A shortage of professionals with dual expertise in automotive engineering and cybersecurity. 2) **Resource Constraints**: The high initial investment for establishing a CSMS and acquiring security tools. 3) **Complex Supply Chain Integration**: Ensuring consistent cybersecurity practices across a multi-tiered supply chain. To overcome these, companies can partner with expert consultants for targeted training, adopt a phased, risk-based implementation to prioritize resources, and standardize supplier security requirements to streamline management.
