DET0734 Detection of Automated Collection

AN1867 Analytic 1867

Real-time network monitoring identifies a source issuing systematic, sequential Industrial Control System (ICS) protocol reads sweeping the full register/address range across multiple field devices within a short time window, from a source not in the approved control server list. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. Suppress normal SCADA/HMI/historian polling, commissioning, asset inventory, backup, diagnostics, and approved engineering activity.

AN2128 Analytic 2128

Real-time monitoring identifies a scripting interpreter process iterating through Industrial Control System (ICS) data sources and writing output to a local file or piping to a network socket, by a User Identifier (UID) not associated with documented automation scripts. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. Suppress normal SCADA/HMI/historian polling, commissioning, asset inventory, backup, diagnostics, and approved engineering activity.

AN2270 Analytic 2270

Real-time monitoring identifies a host process making sequential Industrial Control System (ICS) protocol reads with output piped to a local staging file, from a process not associated with a recognized Human-Machine Interface (HMI) or historian tool. OT operational-fidelity gate: Do not alert on novelty, scan/read volume, or enumeration alone. Alert when the source role is not authorized for discovery/polling and the target scope, address/tag range, protocol, or rate deviates from the established operational baseline. Suppress normal SCADA/HMI/historian polling, commissioning, asset inventory, backup, diagnostics, and approved engineering activity.
