The Critical Role of ISA/IEC 62443-4-2 Certified Computers in Industrial Cybersecurity

 

In the industrial sector, the cybersecurity of operational technology (OT) is as crucial as the physical integrity of the equipment. For suppliers of industrial computers, the ISA/IEC 62443-4-2 certification is not merely a badge of security assurance; it represents a significant value to customers by underlining robust security features that are essential for components used in industrial automation systems. This certification ensures that the products not only meet high security standards but also provide customers with reliable protection against a range of cyber threats, enhancing the overall safety and efficiency of their operations.

 

Understanding ISA/IEC 62443-4-2 in the Cybersecurity Framework

 

Framework Placement

 

ISA/IEC 62443 is structured in several parts, each focusing on different areas of Industrial Automation and Control System Security (IACS)—from general requirements (ISA/IEC 62443-1) to system requirements (ISA/IEC 62443-3) and component requirements (ISA/IEC 62443-4).

Achieving ISA/IEC 62443-4-2 certification indicates that a product has undergone rigorous testing and is proven to effectively manage cybersecurity threats. For industrial computers at the core of many critical infrastructure systems, this certification is essential for ensuring these devices are equipped to protect against, detect, and respond to potential cyber incidents. By utilising certified components, companies can not only reduce security-related expenses but also avoid the time consuming and expensive development of complex security solutions.


Cross-Sector Application of ISA/IEC 62443 and Other Cybersecurity Standards

 

ISA/IEC 62443-4-2 is widely referenced across various sectors within the industrial ecosystem including energy, medical, smart manufacture, and more. This standard forms a crucial part of a broader set of regulations that cater to specific market needs such as IEC 62351 for energy, IEC 80001 for medical IT networks, and TS 50701 for railway systems. Similarly, ISO 27001 serves as an international standard for information security management systems (ISMS), applicable globally across various types of organizations. In the United States, the NIST Cybersecurity Framework (NIST CSF) provides a policy framework of computer security guidance for private sector organizations to assess and improve their ability to prevent, detect, and respond to cyber attacks. Collectively, these standards emphasize risk management and security controls, each addressing these concerns from slightly different angles to suit their respective regional and sector-specific applications.

 

Regulatory compliance and the role of IEC 62443-4-2

 

  • Machinery Directive: Although primarily focused on the physical aspects of machinery safety, the integration of certified industrial computers can contribute to overall machinery compliance, especially in systems where software controls are critical.
  • NIS 2 Directive: Aligning with the NIS 2 requirements, the ISA/IEC 62443-4-2 certified components ensure enhanced security measures, critical for operators of essential services and digital service providers in the EU. Compliance with these standards ensures that industrial computers are fortified against disruptions to the essential services they support.
  • Cyber Resilience Act (CRA): This EU regulation stresses the resilience of digital products, including industrial computers. Certification under ISA/IEC 62443-4-2 places products in a favorable position to meet these new requirements.
  • US IoT Cybersecurity Improvement Act: For manufacturers selling to US federal agencies, compliance with stringent cybersecurity standards such as ISA/IEC 62443-4-2 can facilitate adherence to this act, which mandates that IoT devices purchased by the federal government meet specific security standards.

Enhancing Supply Chain Security: The First Step

 

A comprehensive risk assessment of the supply chain is the initial step for industrial companies. This process involves carefully selecting suppliers who not only deliver products that comply with safety regulations but also align with the specific security requirements of the industrial systems they serve. By focusing on suppliers that provide components with embedded safety functionalities, companies can significantly enhance the security architecture of their automation and control systems right from the device level.
