BS EN IEC 62443-4-1:2018规定了产品安全开发的工艺要求 用于工业自动化和控制系统的产品。它定义了安全开发 生命周期（SDL），用于开发和维护安全产品。这个生命周期 包括安全需求定义、安全设计、安全实施（包括 编码指南）、验证和确认、缺陷管理、补丁管理和 产品寿命终止。这些要求可以应用于新的或现有的生产过程 开发、维护和退役新的或现有的硬件、软件或固件 产品。这些要求适用于产品的开发人员和维护人员，但不适用于 产品的集成商或用户。本文件中要求的摘要列表可以 参见附录B。交叉引用:IEC 62443-2-4:2015IEC 62443-2-4:2015/AMD1:2017IEC 62443-4-2ISO/IEC 15408-1IEC 62443-2-1IEC TR 62443-2-3IEC 62443-3- 3ISO/ISO/IEC 10746-1IEC TR 62443-2-2IEC TR 62443-1-4ISO/IEC 15408-3IEC 62443-3-2ISO/IEC 301111ISO/IEC 27002ISO 9001IEC 62740ISO/IEC 27036-3ISO/IEC 10746-2IEC 61508（所有部分）ISO/IEC 2914147ISO/IEC 29147ISO/IEC 15408-2IEC 15408-2IEC TR 62443-1-2-2ISO/IEC 27001IEC TS 62443-1-1-3IEC TS 62443-1-1IEC TR 62443-3-2009购买时提供的所有当前修改件。

BS EN IEC 62443-4-1:2018 specifies process requirements for the secure development of products used in industrial automation and control systems. It defines a secure development life-cycle (SDL) for the purpose of developing and maintaining secure products. This life-cycle includes security requirements definition, secure design, secure implementation (including coding guidelines), verification and validation, defect management, patch management and product end-of-life. These requirements can be applied to new or existing processes for developing, maintaining and retiring hardware, software or firmware for new or existing products. These requirements apply to the developer and maintainer of the product, but not to the integrator or user of the product. A summary list of the requirements in this document can be found in Annex B.Cross References:IEC 62443-2-4:2015IEC 62443-2-4:2015/AMD1:2017IEC 62443-4-2ISO/IEC 15408-1IEC 62443-2-1IEC TR 62443-2-3IEC 62443-3-3ISO/IEC 10746-1IEC TR 62443-2-2IEC TR 62443-1-4ISO/IEC 15408-3IEC 62443-3-2ISO/IEC 30111ISO/IEC 27002ISO 9001IEC 62740ISO/IEC 27036-3ISO/IEC 10746-2IEC 61508 (all parts)ISO/IEC 29147ISO/IEC 15408-2IEC TR 62443-1-2ISO/IEC 27001IEC TS 62443-1-3IEC TS 62443-1-1IEC TR 62443-3-1:2009All current amendments available at time of purchase are included with the purchase of this document.
