AiVibeIEC 62443-4-1 Secure Product Development Lifecycle
IEC 62443-4-1 specifies secure product development lifecycle requirements for suppliers of industrial automation and control products, covering security requirements, design, implementation, testing, vulnerability handling and updates.
IEC 62443-4-1, Secure product development lifecycle requirements, specifies the processes that suppliers of industrial automation and control products must follow to develop and maintain secure hardware, software and firmware. It defines eight practices: security management, specification of security requirements, secure by design, secure implementation, security verification and validation testing, management of security-related issues, security update management and security guidelines.
Asset owners and integrators increasingly ask suppliers to demonstrate IEC 62443-4-1 conformance, because product security depends on how products are designed, coded, tested and supported over their life. The standard covers threat modelling, secure coding, security testing including penetration testing, handling of vulnerability reports from outside parties, timely delivery and documentation of security updates, and guidance on how products should be installed and hardened. Development organisations can be certified, for example under the ISASecure Security Development Lifecycle Assurance scheme.
The standard uses maturity levels, based on capability maturity concepts, to describe how consistently the practices are applied, from initial, ad hoc work up to continuous improvement. It addresses the development process rather than the security functions of a specific product, which are covered by IEC 62443-4-2 for components and IEC 62443-3-3 for systems. Its practices parallel secure development guidance in other sectors, such as the NIST Secure Software Development Framework.
