DA-211-2022: Security requirements from IEC 62443 for distribution automation systems

This document provides a recommended set of security requirements at system level that allows the major security threats to be mitigated with current technology. It provides guidance on what technical measures to take to secure distribution automation systems.

The requirements are based on the IEC 62443 standard. They have been selected from part IEC 62443-3-3: System security requirements and security. This standard is widely supported by manufacturers and grid operators, allowing the requirements to be more easily implemented.
The requirements have been designed to allow certification based on the new certification schemes being developed for IEC 62443. Together with the threat analysis for distribution automation systems they form a profile for IEC 62443.
