White Paper: IIoT System Implementation and Certification Based on ISA/IEC 62443 Standards

This report explores the use of the ISA/IEC 62443 series of standards for industrial automation and control
systems (IACS) that include cloud-based functionality (i.e., industrial internet of things (IIoT)). The scope of an “IIoT IACS” includes all the systems and components necessary for a complete IACS including sensors, actuators and controllers at the edge, services in the cloud and the communications between edge and cloud.

This report is a companion to the “IIoT Component Certification Based on the 62443 Standard” study, which explores the use of ISA/IEC 62443-4-2, “Technical security requirements for IACS components” for IIoT
components.
