Real-time monitoring identifies a write to Industrial Control System (ICS) project file paths on a Linux engineering station from a User Identifier (UID) not associated with the ICS engineering tool, or from the tool after loading a file from a removable media or network path not in the approved software distribution list. OT operational-fidelity gate: Alert only when execution violates an approved signer/hash/path/parent/process or tool allowlist, or originates from an unauthorized user/tool, and is tied to an OT asset or follow-on OT-relevant action. Suppress vendor-signed software, approved engineering utilities, diagnostics, patching, backup, and documented maintenance.
