工业自动化和控制系统安全——第2-2部分：IACS安全保护方案

[中文适用范围]： IEC PAS 62443-2-2: 2025 为开发、验证、运行和维护一组称为安全保护方案 (SPS) 的技术、物理和过程安全措施提供指导。该文件的目标是为实施 IACS 安全计划 (SP) 的资产所有者提供机制和程序，以确保 SPS 的设计、实施和运行能够管理由网络威胁导致的对其运营设施中包含的每个 IACS 的风险。该文件基于 IEC 62443 系列其他文件中指定的内容，并解释了如何使用这些内容来支持开发技术、物理和过程安全措施，以应对运营阶段对 IACS 的风险。 [外文原描述]： IEC PAS 62443-2-2: 2025 provides guidance on the development, validation, operation, and maintenance of a set of technical, physical, and process security measures called Security Protection Scheme (SPS). The document’s goal is to provide the asset owner implementing an IACS Security Program (SP) with mechanisms and procedures to ensure that the design, implementation and operation of an SPS manage the risks resulting from cyberthreats to each of the IACS included in its operating facility. The document is based on contents specified in other documents of the IEC 62443 series and explains how these contents can be used to support the development of technical, physical, and process security measures addressing the risks to the IACS during the operation phase.
