IEC 62443 is a series of standards that address cybersecurity for operational technology in automation and control systems. The series is divided into different sections and describes both technical and process-related aspects of automation and control systems cybersecurity. The series is also known as ISA/IEC 62443 in recognition of the fact that much of the initial development was done by the ISA99 committee of the International Society for Automation.
