The Core of UNECE R155
UNECE R155 is a comprehensive regulation developed to enhance cybersecurity in the automotive industry. It demands that vehicle manufacturers establish a robust Cybersecurity Management System (CSMS). This system is designed to safeguard against a wide range of cyber threats, ensuring that vehicles are protected from the design stage through to their end-of-life. The regulation requires manufacturers to continuously monitor and respond to emerging cyber risks, maintaining the security of vehicles throughout their lifespan.
Modern vehicles, equipped with advanced technologies like cellular (3G/4G LTE/5G), NFC, GPS, Wi-Fi, and Bluetooth (what we consider connected vehicles), are susceptible to cyber threats. UNECE R155 addresses these vulnerabilities by mandating manufacturers to incorporate cybersecurity measures 'by design'. This means that security needs to be a fundamental part of vehicle design, not an afterthought (typically requiring OTA patches and recalls). The regulation specifies that vehicles must be able to resist, detect, and respond to cyber threats effectively, ensuring the safety and privacy of users.
Implementing UNECE R155 is no small undertaking for vehicle manufacturers. They must demonstrate compliance with the regulation through rigorous testing and certification processes. This includes proving that their vehicles can withstand various cyber threats and that they have processes in place for ongoing risk assessment and incident response. Compliance with UNECE R155 is critical for manufacturers to sell their vehicles in markets adhering to these regulations, making it a global standard for automotive cybersecurity.
The following is a ‘cheatsheet’ I put together breaking down the document structure of the regulation for quick review of relevant sections (link to the full document source below the table):

One of the notable aspects of UNECE R155 is its detailed approach to potential threats. The regulation identifies 70 specific cybersecurity threats, which I have categorized into seven common cybersecurity domains. Keep in mind that domains do not exactly align with the specifics of UNECE R155, but provide a frame of reference for cybersecurity professional coming from outside the automotive industry:
Physical access control — address threats related to unauthorized physical access to vehicle components (e.g., tampering, theft intrusion).
Network security — involve threats to the vehicle's internal and external communication networks (e.g., hacking, malware, interception).
Software security — identify risks associated with the software running on the vehicle, including its operating system and applications (e.g., exploits, injection, unauthorized access).
Data privacy and protection — pertain to threats targeting the confidentiality and integrity of data collected and processed by the vehicle (e.g., breach, tampering, unauthorized access).
Operational security — detail threats that impact the vehicle's operational functionality and safety systems come into play (e.g., manipulation, disruption, interference).
Remote access control — highlight risks associated with remote access to the vehicle’s systems, often through wireless connections (e.g., hijacking, exploitation, unauthorized access).
Supply chain security — cover threats originating from vulnerabilities within the supply chain, including those from third-party suppliers and service providers (e.g., malicious attacks, vulnerabilities, counterfeit components).
Each regulation-defined category pertains to different facets of a vehicle's digital infrastructure, encompassing everything from onboard computer systems and software to external communication networks and data privacy. This comprehensive categorization ensures that manufacturers address the full range of vulnerabilities in their vehicles.
Beyond the establishment of a CSMS, UNECE R155 stipulates that manufacturers must obtain a certificate of compliance (read: time, money, and suffering). This certificate is not a one-time acquisition but requires ongoing adherence to the set standards. It serves as a formal recognition that a manufacturer's CSMS meets the specific requirements laid out by the regulation. Importantly, this compliance must be demonstrated for each new type of vehicle produced. Manufacturers are tasked with ensuring that every new model follows the processes and protections approved as part of their CSMS.
The regulation's emphasis on compliance for every new vehicle underscores its commitment to long-term cybersecurity. As technology evolves and new threats emerge, UNECE R155 ensures that the latest vehicles are equipped to handle these challenges. This approach not only enhances the safety and integrity of individual vehicles but also contributes to the broader goal of fostering a more secure and resilient automotive industry.
