Abstract
This document provides the cyber security technical requirements for the components in the context of operational technology (OT), specifically the embedded devices, network components, host components and software applications. Annex B describes the explicit and implicit assumptions about the product´s properties and capabilities. Annex C provides a security evaluation methodology based on the secure development lifecycles and the component requirements. The purpose of this amendment is to identify and modify the requirements and associated clauses to align with the EU Cyber Resilience Act essential cybersecurity requirements, so that the amendment (EN IEC 62443-4-2:2019/prAA:2025), once made available by CENELEC, can be offered for citation under the Cyber Resilience Act.
