Real-time monitoring identifies Simple Network Management Protocol (SNMP) SET commands to power Management Information Base (MIB) restart Object Identifiers (OIDs) or Command Line Interface (CLI) reload commands from a source not in the approved Network Management System (NMS) Classless Inter-Domain Routing (CIDR). 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.
