Real-time monitoring identifies an Industrial Control System (ICS) protocol session that systematically enumerates a device's full tag/object namespace from a source not in the approved control server list, where the enumeration pattern covers the complete address/object space rather than the sparse, fixed tag set legitimate Supervisory Control and Data Acquisition (SCADA) polling queries. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. Suppress normal SCADA/HMI/historian polling, commissioning, asset inventory, backup, diagnostics, and approved engineering activity.
