BS EN IEC 62443-4-1:2018

## BS EN IEC 62443-4-1:2018: Secure Product Development Lifecycle RequirementsBS EN IEC 62443-4-1:2018 is a critical industrial cybersecurity standard that specifies requirements for the secure development of products used in industrial automation and control systems (IACS). This standard is part of the IEC 62443 series, which provides a comprehensive framework for addressing and mitigating security vulnerabilities in IACS.### Key Features and Benefits:- **Secure Product Development Lifecycle**: Defines a secure product development lifecycle (SDLC) to ensure that security is integrated into the design, implementation, and maintenance of IACS products.- **Secure Design Principles**: Outlines secure design principles and practices to minimize the introduction of vulnerabilities during the product development process.- **Vulnerability Management**: Establishes requirements for vulnerability management, including identification, assessment, and remediation of security vulnerabilities.- **Secure Deployment and Maintenance**: Provides guidance on secure deployment, configuration, and maintenance of IACS products to maintain their security posture over the product's lifecycle.- **Compliance and Risk Mitigation**: Helps organizations comply with regulatory requirements and industry best practices, reducing the risk of cyber threats and security breaches in their industrial environments.### Technical Specifications:- **Scope**: Applies to the secure development of products used in industrial automation and control systems, including hardware, software, and firmware.- **Normative References**: Refers to other relevant IEC 62443 standards and technical specifications.- **Secure Development Lifecycle Phases**: Defines the following phases of the secure product development lifecycle: - Requirements, Design, and Implementation - Verification and Validation - Release - Maintenance and End-of-Life- **Security Capabilities**: Outlines security capabilities that should be incorporated into the product development process, such as: - Security Requirements Specification - Secure Design Principles - Secure Coding Practices - Security Verification and Validation - Vulnerability Management - Secure Deployment and Configuration - Maintenance and End-of-Life SupportBy implementing the requirements specified in BS EN IEC 62443-4-1:2018, organizations can ensure that their IACS products are developed with security in mind, reducing the risk of cyber threats and protecting their critical industrial infrastructure.
