DET0739 Detection of Remote System Discovery
AN1872 Analytic 1872
Real-time monitoring identifies execution of network discovery tools (nmap, PLCScan, redpoint NSE scripts) or Industrial Control System (ICS)-specific scanners from an Industrial Control System (ICS) Windows host, from a process not associated with a recognized network management or engineering 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.
AN2132 Analytic 2132
Real-time monitoring identifies execution of network discovery tools on an Industrial Control System (ICS) Linux asset by a User Identifier (UID) that does not normally perform network scanning. 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.
AN2171 Analytic 2171
Real-time network monitoring identifies a source generating Industrial Control System (ICS) discovery broadcasts or sequential connection attempts across the full IP range of a device subnet, from a source not in the approved engineering/Supervisory Control and Data Acquisition (SCADA) inventory. Documented in the PIPEDREAM/INCONTROLLER toolset's CODECALL module for EtherNet/IP device discovery. 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.
AN2172 Analytic 2172
Real-time monitoring identifies Internet Control Message Protocol (ICMP) echo sweeps, Address Resolution Protocol (ARP) broadcast floods, or Industrial Control System (ICS)-specific discovery protocol packets from a host generating traffic to all IPs in a subnet in sequential order, a sweep pattern distinct from normal operational traffic to known device Internet Protocol (IP) addresses only. 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.

Exact source tags are not semantic relevance verdicts. Review actual rule conditions and observation points; imported rules are not backend-compiled or live-validated.
Pinned research references. No browser attack runner or production-validated detector is asserted. Imported procedures remain unvalidated; any bounded lab evidence has its own scope. ATT&CK / Atomic provenance · Detection provenance.
