Real-time monitoring identifies a Linux process opening Industrial Control System (ICS) protocol master connections to multiple field device Internet Protocol (IP) addresses, from a host that is not the authorized Supervisory Control and Data Acquisition (SCADA) server. 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.
