标准范围

IEC TR 62541-2:2016（E）是一份技术报告，描述了OPC统一体系结构（OPC UA）安全模型。它描述了OPC UA预计运行的物理、硬件和软件环境的安全威胁。它描述了OPC UA如何依赖其他安全标准。它提供了OPC UA规范本部分和其他部分中使用的通用安全术语的定义。它概述了OPC UA规范其他部分中规定的安全功能。它引用了在本多部分规范的其他部分中规范指定的服务、映射和概要文件。它提供了关于实现安全性的建议或最佳实践指南。IEC 62541的本部分与IEC 62541的其中一个规范性部分之间的任何看似模糊之处，都不会消除或减少规范性部分中规定的要求。第二版取消并取代了2010年发布的IEC TR 62541-2第一版。第二版未对第一版进行任何技术性修改，但为确保完整性，对第二版进行了大量澄清和补充。

IEC TR 62541-2:2016(E) is a Technical Report and describes the OPC unified architecture (OPC UA) security model. It describes the security threats of the physical, hardware, and software environments in which OPC UA is expected to run. It describes how OPC UA relies upon other standards for security. It provides definition of common security terms that are used in this and other parts of the OPC UA specification. It gives an overview of the security features that are specified in other parts of the OPC UA specification. It references services, mappings, and Profiles that are specified normatively in other parts of this multi-part specification. It provides suggestions or best practice guidelines on implementing security. Any seeming ambiguity between this part of IEC 62541 and one of the normative parts of IEC 62541 does not remove or reduce the requirement specified in the normative part. This second edition cancels and replaces the first edition of IEC TR 62541-2, published in 2010. This second edition includes no technical changes with respect to the first edition but a number of clarifications and additional text for completeness.
