Real-time monitoring identifies an Industrial Control System (ICS) protocol write to an existing program block from a source not in the approved engineering workstation list, outside a scheduled change-control window, correlated against post-modification program hash comparison and measurable change in controller Input/Output (I/O) behavior. OT operational-fidelity gate: Alert only when the action is not attributable to an authorized operator/engineering source for the specific target and function, and it is either outside an approved change/maintenance window or lacks matching change-control context; where telemetry permits, require corroborating device, configuration, or process-state effect. Suppress activity that fully matches approved maintenance, commissioning, failover, recovery, or tested control procedures.
