IEC 62443-4-2:2019/COR1:2022

IEC 62443-4-2:2019/COR1:2022 is a supporting corrigendum to the technical requirements for industrial automation and control systems components, based on Security for industrial automation and control systems - Part 4-2: Technical security requirements for IACS components. It is relevant for organizations reviewing cybersecurity obligations, documenting technical compliance, or checking whether a component-level security reference has been updated correctly. As a corrigendum to the parent document, it should be used together with IEC 62443-4-2:2019 in engineering, procurement, and conformity assessment workflows.

What is IEC 62443-4-2:2019/COR1:2022?

This corrigendum provides a formal correction linked to IEC 62443-4-2:2019, which addresses technical security requirements for components used in industrial automation and control systems. In practice, it helps maintain the accuracy of the parent technical reference used for security specification, technical review, and documented evaluation. For teams working on product development or compliance preparation, IEC 62443-4-2:2019/COR1:2022 is a supporting document that may be needed to keep conformity assessment records aligned with the corrected source material.

Applications of IEC 62443-4-2:2019/COR1:2022

IEC 62443-4-2:2019/COR1:2022 is typically used in workflows involving industrial control components, security requirements review, and technical validation of product documentation. It may be relevant for manufacturers, test laboratories, integrators, and procurement teams evaluating whether component-level security requirements are being applied consistently across design and verification activities. The corrigendum can also support quality workflows where the latest corrected wording must be reflected in compliance files, engineering documentation, or supplier assessment packages.

Why is IEC 62443-4-2:2019/COR1:2022 important?

Corrective references such as IEC 62443-4-2:2019/COR1:2022 matter because even small editorial changes can affect how technical requirements are interpreted in security, testing, and procurement processes. Using the corrected document helps reduce ambiguity during engineering validation, conformity assessment preparation, and internal compliance checks. For organizations working with industrial automation and control systems, it supports operational consistency, improves technical review accuracy, and helps ensure that product evaluation and risk management activities are based on the current referenced wording.

• Supporting corrigendum to the parent security requirements document for IACS components
• Useful for maintaining accurate compliance references and controlled engineering documentation
• Relevant to product evaluation, laboratory review, and conformity assessment preparation
• Helps align procurement and quality workflows with the corrected technical source
