Analytic 1924

Real-time monitoring identifies Industrial Control System (ICS) master-role command traffic originating from a source not in the approved control server inventory, directed at multiple field devices in a pattern consistent with control-server behavior. Documented in Maroochy Water Services (falsified PDS/station addresses to impersonate the master) and the 2017 Dallas Siren incident (rogue radio transmitter to 156 sirens). OT operational-fidelity gate: Alert only when the master/station identity or source is not authorized for the target device and command function, or when a normally authorized master violates its configured role/sequence and produces a corroborating device/process-state change. Suppress legitimate redundancy/failover, hot-standby promotion, commissioning, and approved engineering master activity.
