The semiconductor industry faces escalating cybersecurity threats as it becomes increasingly digitized, making it a critical target with potential national security implications. This presentation examines the convergence of two pivotal cybersecurity frameworks: the ISA/IEC 62443 industrial automation security standards and the European Union's Cyber Resilience Act (CRA), and their collective impact on semiconductor manufacturing compliance.
The ISA/IEC 62443 series provides a comprehensive framework for securing industrial automation and control systems (IACS) throughout their lifecycle. Recognized as the gold standard for operational technology (OT) cybersecurity, these standards establish security levels, define risk assessment processes, and implement defense-in-depth strategies using zones and conduits segmentation. For semiconductor fabs, among the world's most sophisticated manufacturing facilities requiring atomic-level precision, ISA/IEC 62443 offers critical guidance for protecting complex automated systems while maintaining operational continuity.
The EU Cyber Resilience Act, which entered into force on December 10, 2024, introduces mandatory cybersecurity requirements for all products with digital elements sold in the European market. With full compliance required by December 11, 2027, the CRA establishes essential cybersecurity requirements, vulnerability handling processes, and CE marking requirements. This regulation significantly impacts semiconductor manufacturers and suppliers, as semiconductor components are embedded in virtually all connected devices covered by the CRA.
The semiconductor industry presents unique compliance challenges including managing complex global supply chains, protecting valuable intellectual property, ensuring continuous production in high-precision environments, and addressing IT/OT convergence. The integration of ISA/IEC 62443 and CRA compliance creates both opportunities and challenges: while ISA/IEC 62443 provides operational frameworks for securing manufacturing processes, the CRA ensures end-to-end product security throughout the digital supply chain.
Key compliance challenges identified include navigating overlapping requirements between standards, managing assessment complexity across diverse supplier networks, implementing OT zero-trust architectures in semiconductor fabs, ensuring continuous vulnerability management, and maintaining compliance documentation throughout product lifecycles. Industry initiatives such as SEMI E187 (Semiconductor Equipment Cybersecurity Standard) and collaborative efforts through the SEMI Cybersecurity Consortium demonstrate the sector's proactive approach to standardizing security practices.
This presentation contributes to understanding how semiconductor manufacturers can develop integrated compliance strategies that leverage ISA/IEC 62443's operational technology expertise while meeting CRA's product-level security requirements. The discussion highlights that successful compliance requires a holistic approach combining risk-based security frameworks, supply chain collaboration, and continuous security lifecycle management.
