Scope

This document relates to the network security of measurement devices (PMDs meeting the requirements of IEC 61557-12 and PQIs meeting the requirements of IEC 62586-1) and data acquisition devices (devices meeting the requirements of IEC 62974-1) intended for installation in access-restricted areas.
This document addresses the network security aspects of devices used for power measurement and monitoring, power quality monitoring, and data acquisition (e.g., device hardening or device recovery), but does not include organizational network security requirements (e.g., end-user security policies).
Note: Organizational network security is critical for the reliable operation of devices.
This document aims to raise awareness of network security among manufacturers and other stakeholders and provide basic guidance for mitigating security risks:
—— This document is consistent with the device/system approaches described in standards such as IEC 62443 (all parts) and ISO/IEC 27001;
—— This document is based on common system use cases.
This document does not apply to trade settlement meters covered by the IEC 62053-2X series of standards.
