Connected Vehicle Cybersecurity

Connected Vehicle Cybersecurity refers to the systematic protection of digital systems in connected vehicles, including ECU, OTA, and V2X. According to ISO 21434:2021, it covers the entire vehicle lifecycle from design to decommissioning. This involves managing risks from various digital interfaces, ensuring data--driven safety and regulatory compliance. It differs from traditional automotive security by addressing the complexities of interconnected systems, including V2X and cloud-based services, which increase the attack surface for malicious actors. Companies must be closely closely monitoring emerging threats to ensure vehicle safety and data--driven privacy, especially as regulations like UNECE WP.29 become globally applicable.

Implementation typically follows three steps: first, conducting Threat Analysis and Risk Assessment (TARA) according to ISO 21434 to identify digital vulnerabilities. Second, establishing a robust supplier cybersecurity management system to ensure third-party components meet security requirements. Third, implementing continuous monitoring, incident response, and OTA update capabilities. For example, a major Taiwanese automotive supplier implemented TARA across its entire product line, reducing critical vulnerabilities by 40% within the first year. Key performance indicators (KPIs) include the Mean Time to Remediate (MTTR) vulnerabilities and the percentage of compliant suppliers, with a target of 100% compliance for all new product launches.

Taiwan enterprises face three primary challenges: fragmented supplier capabilities, regulatory divergence (local vs. international), and a shortage of cross-disciplinary talent. To overcome these, companies should first implement a tiered supplier management system, requiring smaller suppliers to meet minimum security standards. Second, adopting a 'global compliance first' approach ensures that products meet both Taiwan's local regulations and international standards like ISO 21434 and UNECE WP.29. Finally, investing in talent development through partnerships with universities or specialized training can bridge the expertise gap. The initial phase should focus on a 90-day foundation-building period, followed by a 6-month full implementation cycle.
