BS EN IEC 62443-4-1 is a part of the IEC 62443 multi-series that discusses security for industrial automation and control systems.
BS EN IEC 62443-4-1 specifies process requirements for the secure development of products used in industrial automation and control systems. BS EN IEC 62443-4-1 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.
Note: These requirements apply to the developer and maintainer of the product, but not to the integrator or user of the product.
BS EN IEC 62443-4-1 on secure product development lifecycle requirements is useful for:
The purpose of the security management practice is to ensure that the security-related activities are adequately planned, documented and executed throughout the product’s life-cycle. If care is not taken in planning and supporting the activities related to security, then those activities can be rendered ineffective due to inadequate resources, insufficient time or process inefficiencies.
BS EN IEC 62443-4-1 describes product development life-cycle requirements related to cyber security for products intended for use in the industrial automation and control systems environment. BS EN IEC 62443-4-1 also provides you with guidance on how to meet the requirements described for each element.
In conclusion, the guidelines of BS EN IEC 62443-4-1 ensure the security and efficiency of automation and control devices, thereby maintaining their integrity and reliability.
