Cybersecurity Standards: IEC 62443, CRA, RED-DA
．IEC 62443 is a globally recognized and widely adopted cybersecurity standard for Industrial Automation and Control Systems (IACS). Unlike traditional IT security, it is specifically designed to maintain the availability and integrity of operational technology (OT) environments. The standard defines the interrelationships between four key roles: Asset Owners, Service Providers, System Integrators, and Product Suppliers. IEC 62443 empowers organizations to identify vulnerabilities, mitigate cyberattacks, and establish resilient architectures. This ensures that industrial infrastructure can effectively prevent potential risks and safety threats throughout the digital transformation process.
．The Cyber Resilience Act (CRA) was introduced by the European Union (EU) and requires mandatory compliance starting on December 11, 2027. It aims to enhance the cybersecurity standards of digital products and software, ensuring that security is incorporated throughout the entire lifecycle—from design to usage. By introducing mandatory regulations, the act seeks to improve market trust and transparency. The CRA applies to products and software with digital elements that can connect directly or indirectly to other devices or networks. However, certain products, such as medical devices, vehicles, and aviation equipment, are excluded from its scope. The act targets hardware manufacturers, service providers, and software developers, setting standards for product planning, design, development, and maintenance.
．The Radio Equipment Directive Delegated Act (RED-DA) is a supplemental delegated act to the European Union's current Radio Equipment Directive (RED). It establishes higher safety and performance standards for wireless equipment, enhancing compliance and market adaptability, It establishes enhanced security and performance standards for radio equipment to strengthen compliance and market adaptability.
The act mandates three fundamental cybersecurity requirements, corresponding to Articles 3.3(d), (e), and (f) of the RED: preventing harm to communication networks, protecting the privacy of user personal data, and reducing the risk of fraudulent transactions. The technical requirements of RED-DA are aligned with the EN 18031 series of harmonized standards, covering three primary domains: network protection, privacy protection, and fraud prevention. Mandatory from August 1, 2025, RED-DA compliance is essential for EU market access. Manufacturers must integrate cybersecurity into design and production, ensuring regulatory compliance through standardized testing to enhance product safety and competitiveness.
