Real-time monitoring identifies a user-invoked action on an Industrial Control System (ICS) workstation immediately followed by a process execution chain inconsistent with normal ICS operations -- the user-driven trigger plus the resulting anomalous execution chain together distinguish this from generic malware execution. OT operational-fidelity gate: Alert only when the account/device/session violates the approved identity + source host/jump path/zone policy and is corroborated by access to a protected OT asset, execution, configuration change, or another security-relevant follow-on event. Suppress approved shift activity, vendor support, break-glass use, commissioning, and documented remote-access windows.
