IEC PAS 62443-1-6:2025 PDF

IEC PAS 62443-1-6:2025 introduces new communication channels, a new organization of functions, and new cybersecurity concerns. Asset owners are looking for more guidance in how to deal with all these changes. The IEC 62443 series, Security for industrial automation and control systems, can be applied to this new technology, but many asset owners look at the scope of the series and wonder where to start. This part of IEC 62443 seeks to give guidance to asset owners and their service providers on how the IEC 62443 series can be used to address IIoT. The document points to requirements in the different parts of the IEC 62443 series that might be helpful to the asset owner as they both consider implementing IIoT in their automation solutions as well as dealing with existing IIoT. Product suppliers and service providers can find this document useful as well. NOTE The drafting committee for IEC 62443 is currently engaged in revision of parts of the standard to recognize emerging technologies, such as IIoT, and this document is part of that on-going effort. NOTE In accordance with ISO/IEC Directives, Part 1, IEC PASs are automatically withdrawn after 4 years.
