CSA IEC 62443-4-1:20

CSA Preface This is the first edition of CSA IEC 62443-4-1, Security for industrial automation and control systems — Part 4-1: Secure product development lifecycle requirements , which is an adoption without modification of the identically titled IEC (International Organization for Standardization) Standard 62443-4-1 (first edition, 2018-01). For brevity, this Standard will be referred to as “CSA IEC 62443-4-1” throughout. This Standard is one in a series of Standards developed by IEC/TC 65 on industrial automation networking security that are being adopted by CSA Group. This Standard 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. It is intended to be used by the developer and maintainer of the product, but not by the integrator or user of the product. This Standard uses terminology and concepts specified in CAN/CSA-IEC/TS 62443-1-1:17, Industrial communication networks — Network and system security — Part 1-1: Terminology, concepts and models. This Standard was reviewed for Canadian adoption by both the CSA Technical Committee on Operational Technology, Functional Safety, and Security and the CSA Technical Committee on Information Technology, under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology, and has been formally approved by the CSA Technical Committee on Information Technology. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of IEC 62443 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.
