Real-time monitoring identifies an Industrial Control System (ICS) network-device command-line interface (CLI) commands (e.g., interface shutdown, access control list modification, network address translation changes, etc.) from a source or account outside the approved network-management baseline or network traffic patterns consistent with scripted command execution -- regular-interval connections with consistent payload sizes -- to field device Internet Protocol (IP) addresses from a host not normally exhibiting such regularity. Operational Technology (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.
