Vehicle-to-Everything communication

Vehicle-to-Everything (V2X) communication is an umbrella term for technologies that allow vehicles to communicate with their surroundings, enhancing road safety and enabling autonomous driving. It comprises several types: Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N). In enterprise risk management, V2X is a critical external attack surface. The ISO/SAE 21434 standard mandates a Threat Analysis and Risk Assessment (TARA) for V2X systems to mitigate threats like message spoofing, denial-of-service attacks, and data eavesdropping. Unlike in-vehicle networks (e.g., CAN bus), V2X operates in an open environment, necessitating robust security controls. Standards such as IEEE 1609.2 for security services and the ETSI ITS-G5 series for communication architecture provide the framework for securing V2X communications and ensuring interoperability.

Applying V2X in enterprise risk management focuses on securing its communication channels to comply with regulations like UN R155 and standards such as ISO/SAE 21434. A practical three-step approach includes: 1) Threat Analysis and Risk Assessment (TARA), where potential threats to V2X interfaces, like spoofed safety messages, are identified and their impact is assessed. 2) Implementation of Security Controls, which involves deploying a Public Key Infrastructure (PKI) compliant with IEEE 1609.2 to authenticate and ensure the integrity of messages, alongside an Intrusion Detection and Prevention System (IDPS). 3) Continuous Monitoring and Incident Response, managed through a Vehicle Security Operations Center (VSOC) to detect anomalies and manage threats throughout the vehicle lifecycle. Implementing these steps can significantly reduce V2X-related security incidents and ensure a higher pass rate for cybersecurity audits, securing market access for automotive products.

Taiwanese enterprises face three primary challenges in V2X implementation. First, regulatory fragmentation and standards divergence (DSRC vs. C-V2X) create uncertainty for product development, especially for export-oriented suppliers. Second, the high cost of establishing and maintaining a trusted Public Key Infrastructure (PKI) for vehicle credentials poses a significant financial barrier for small and medium-sized enterprises. Third, there is a severe talent gap for professionals with expertise across automotive engineering, wireless communication, and cybersecurity. To overcome these, companies should adopt flexible, multi-standard hardware platforms. They can also join industry consortiums or leverage government-led initiatives to share PKI costs. As a priority, partnering with specialized consultants to conduct a gap analysis against ISO/SAE 21434 and initiate cross-disciplinary training programs within 3-6 months is crucial to accelerate compliance and bridge the talent gap.
