UN R 155 - Cyber security and cyber security management system

UN Regulation No. 155, issued by the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29), is a binding international regulation for the automotive industry. It mandates that vehicle manufacturers implement and maintain a certified Cybersecurity Management System (CSMS) to obtain type approval for new vehicles. The regulation's scope covers the entire vehicle lifecycle, including development, production, and post-production phases. It is operationally supported by the ISO/SAE 21434 standard, which provides a detailed framework for compliance. This regulation elevates cybersecurity to the same level of importance as traditional vehicle safety (governed by ISO 26262).

Applying UN R 155 involves integrating cybersecurity into an organization's core risk management framework. Key steps include: 1) Establishing a CSMS compliant with ISO/SAE 21434, defining governance and policies. 2) Conducting a Threat Analysis and Risk Assessment (TARA) for each vehicle type to identify vulnerabilities. 3) Implementing and validating security controls based on TARA findings, such as intrusion detection systems (IDS). Measurable outcomes include a 100% type approval success rate, reducing critical vulnerabilities in pre-production by over 80%, and passing all regulatory audits, thereby securing market access.

Taiwanese enterprises, primarily component suppliers, face three key challenges. First, complex supply chain coordination, as they must align their CSMS with multiple OEMs' varying requirements. Second, a talent gap for professionals skilled in both automotive engineering and cybersecurity. Third, the high cost of implementation poses a financial burden for SMEs. To overcome these, companies should establish standardized security interfaces, invest in targeted training, and leverage external consultants to implement a compliant framework efficiently. A phased approach can help manage costs and build capabilities incrementally.
