Real-time monitoring identifies a Universal Serial Bus (USB) storage device insertion event on an Industrial Control System (ICS) engineering or Human-Machine Interface (HMI) workstation where the device's hardware identifier (ID) is not in the authorized USB allowlist, immediately followed by process execution from the removable drive's path. Documented as the primary infection vector for Stuxnet, which specifically targeted air-gapped Siemens engineering environments via infected USB drives. 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.
