Road vehicles—Cybersecurity engineering (ISO 21434)

ISO 21434, titled "Road vehicles—Cybersecurity engineering," is an international standard published by the International Organization for Standardization (ISO 21434:2021). Its primary goal is to provide a systematic framework for managing cybersecurity risks throughout the entire lifecycle of road vehicles, from concept and development to production, operation, and decommissioning. Developed in response to the increasing connectivity and automation of vehicles and the corresponding rise in cyber threats, this standard ensures that cybersecurity considerations are integrated from the initial design phase. It works in conjunction with functional safety standard ISO 26262, establishing a dual defense line for vehicle safety and security. It helps automotive manufacturers and their suppliers identify, assess, treat, and monitor cybersecurity risks effectively, aligning with international regulations such as UNECE WP.29 R155.

The practical application of ISO 21434 in enterprise risk management spans various stages of the product lifecycle. Firstly, **cybersecurity risk assessment** is a core step, where organizations identify vehicle assets, potential threats, and vulnerabilities, then evaluate their impact and feasibility, often using methods like Threat Analysis and Risk Assessment (TARA). Secondly, based on the risk assessment, clear **cybersecurity goals and requirements** are defined and integrated into the product design and development processes. For instance, during Telematics Control Unit (TCU) design, requirements for encrypted communication and secure boot must be considered. Finally, through **cybersecurity verification and validation**, products undergo penetration testing and fuzz testing to ensure the effectiveness of cybersecurity measures. Major global automotive manufacturers like BMW and Mercedes-Benz, along with their suppliers, have adopted ISO 21434 into their R&D processes to comply with UNECE WP.29 R155, achieving over 95% compliance rates and anticipating a 30% reduction in recall costs due to cybersecurity vulnerabilities.

Taiwan enterprises encounter several challenges when implementing ISO 21434. Firstly, **lack of technical expertise and talent** is a primary bottleneck, with a shortage of engineers and managers possessing specialized automotive cybersecurity knowledge. Secondly, Taiwan's automotive supply chain is complex, making **supply chain integration and collaboration** difficult, hindering the effective dissemination and execution of cybersecurity requirements. Thirdly, implementing the standard demands significant investment in tools, training, and process re-engineering, posing **cost and resource constraints** for SMEs. To overcome these, enterprises can: 1. **Enhance talent training and external partnerships**: Collaborate with expert consulting firms like Winners Consulting to gain specialized knowledge and build internal teams through training. 2. **Establish supply chain collaboration mechanisms**: Develop unified cybersecurity requirements and communication platforms, encouraging suppliers to jointly implement the standard, ensuring end-to-end security. 3. **Phased implementation and benefit evaluation**: Start with small-scale projects, gradually expand, and quantify benefits (e.g., 15% reduction in risk incidents) to secure top management support. Core system establishment can be achieved within 12-18 months.
