Automotive Security Requirements Verification

Automotive Security Requirements Verification is a structured engineering process of providing objective evidence that a vehicle's systems or components fulfill their predefined cybersecurity requirements. Mandated by regulations like UN R155 and the ISO/SAE 21434 standard, it is a critical phase in the V-model development lifecycle. The process involves systematic testing, analysis, and review to ensure that security controls, derived from a Threat Analysis and Risk Assessment (TARA), are correctly and completely implemented. Unlike general functional testing, it specifically focuses on the system's resilience against malicious attacks, validating attributes like confidentiality, integrity, and availability. The outputs, such as test reports and analysis results, form the core of the Cybersecurity Case, which is essential for achieving vehicle type approval and demonstrating due diligence in risk management.

In practice, enterprises apply Automotive Security Requirements Verification through a multi-step process. First, they establish a traceability matrix linking security requirements to design artifacts, code, and test cases. Based on the TARA, they plan specific verification activities, such as penetration testing for high-risk interfaces. Second, they execute these activities, which can include Static/Dynamic Application Security Testing (SAST/DAST), fuzz testing, and hardware security analysis, meticulously documenting all results. Finally, they analyze the findings, prioritize vulnerabilities for remediation, and compile a comprehensive verification report. This report serves as crucial evidence for the Cybersecurity Case submitted to OEMs or authorities. For example, a Taiwanese Tier-1 supplier successfully used this process to achieve a 100% UN R155 audit pass rate for its ECU, reducing post-launch security patching costs by over 30%.

Taiwanese enterprises face three primary challenges. First, a significant talent gap exists, with a shortage of professionals skilled in both automotive engineering and cybersecurity, leading to difficulties in interpreting and applying ISO/SAE 21434. Second, the high cost of specialized tools and test environments, such as Hardware-in-the-Loop (HIL) systems and professional fuzzing tools, presents a major financial barrier for small and medium-sized suppliers. Third, complex supply chain collaboration is a hurdle, as ensuring vehicle-level security requires seamless integration and clear responsibility-sharing, which is often hindered by the lack of standardized Cybersecurity Interface Agreements (CIAs). To overcome these, companies can partner with expert consultants for training and outsourced testing, leverage cloud-based Testing-as-a-Service (TaaS) to reduce initial investment, and implement standardized CIAs to streamline supplier collaboration.
