Vehicle-to-Everything (V2X)

Vehicle-to-Everything (V2X) is an umbrella term for communication technologies that allow vehicles to exchange data with their surroundings, encompassing Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N). Its primary goal is to enhance road safety and traffic efficiency. In enterprise risk management, V2X is a critical attack surface due to its external interfaces. The ISO/SAE 21434 standard mandates a systematic Threat Analysis and Risk Assessment (TARA) for V2X systems. Furthermore, UN Regulation No. 155 requires automotive manufacturers to implement a certified Cyber Security Management System (CSMS) to continuously monitor and respond to threats originating from V2X communications throughout the vehicle lifecycle, ensuring ongoing security.

To manage V2X risks, enterprises must follow structured steps. First, conduct a Threat Analysis and Risk Assessment (TARA) per ISO/SAE 21434 to identify threats like message spoofing and assess their safety impact. Second, implement a Security Credential Management System (SCMS) compliant with IEEE 1609.2, using a Public Key Infrastructure (PKI) to issue digital certificates that ensure message authenticity and integrity. Third, deploy an Intrusion Detection and Prevention System (IDPS) in the Telematics Control Unit (TCU) to monitor V2X traffic for anomalies and report incidents to a Vehicle Security Operations Center (VSOC). A leading OEM reduced critical V2X security risks by over 85% and achieved UN R155 type approval using this process, enabling market access in 50+ countries.

Taiwanese enterprises face three key challenges with V2X. First, regulatory fragmentation requires them to support different standards (e.g., DSRC vs. C-V2X) and comply with multiple regulations like UN R155 and ISO/SAE 21434, increasing complexity. Second, as suppliers, they struggle to provide the comprehensive TARA reports and cybersecurity documentation demanded by global OEMs due to a lack of in-house expertise. Third, resource constraints make it difficult for SMEs to establish and operate a 24/7 Vehicle Security Operations Center (VSOC). Solutions include adopting modular hardware designs, partnering with consultants to implement standardized cybersecurity processes (e.g., Cybersecurity ASPICE), and leveraging VSOC-as-a-Service models to reduce upfront costs.
