This white paper discusses the topic of component certification within the framework of the ISA/IEC 62443 standards, specifically focusing on Part III. It outlines the significance of security levels (SLs) in relation to component certifications and how these certifications are essential for ensuring that components meet the required security standards. The document explains the concept of component requirements, detailing how they are utilized in the certification process to achieve a specific capability security level (SL-C). It also describes the relationship between achieved security levels (SL-A) and target security levels (SL-T), emphasizing that the actual security level achieved by a component depends on various factors, including proper installation and maintenance. Furthermore, the paper categorizes components into four distinct types as defined in the IEC 62443-4-2 standard, providing insights into their characteristics and examples. This structured approach aims to enhance understanding of component certification processes and requirements in cybersecurity for industrial automation and control systems.
