ISO 15408

ISO 15408, also known as Common Criteria (CC), is an international collection of standards used to evaluate the security of IT products. It provides a common language for security-related claims, allowing different nations to recognize each other's evaluations. The standard defines Security Targets (ST), Evaluation Assurance Levels (EAL 1-7), and specific methodologies for testing. In the automotive context, it complements ISO/SAE 21434 by providing a verifiable mechanism to prove that the security measures claimed by a manufacturer actually function as intended, which is critical for compliance with UN R155 and the EU CRA (Cyber Resilience Act).

Implementation typically follows a three-step approach: 1) Security Requirement Mapping: Translating threat scenarios identified in ISO/SAE 21434 into specific technical requirements measurable by ISO 15408. 2) Assurance Level Selection: Based on the criticality of the automotive component (e.g., ADAS vs. Infotainment), enterprises select the appropriate EAL level (EAL4+ is common for safety-critical systems). 3) Third-party Evaluation: Engaging accredited labs to perform the assessment. Real-world-use cases show that automotive suppliers using ISO 15408-aligned methodologies experience a 40% reduction in post-release security patches due to better-verified design-time security controls.

Taiwanese enterprises face three primary challenges: high certification costs, lack of specialized technical talent, and the complexity of managing multiple international standards simultaneously. To overcome these, enterprises should: A) Prioritize high-risk components for EAL assessment to optimize budget-to-risk ratio. B) Partner with international consulting firms like Winners Consulting to bridge the talent gap. C) Integrate ISO 15408-aligned processes into the existing ISO/SAE 21434-compliant development lifecycle to ensure continuous compliance without starting from scratch. This strategic approach typically yields a 25% faster time-to-market for security-sensitive automotive products.
