Analytic 2191

Real-time monitoring identifies network device management commands succeeding from a source not in the approved Network Management System (NMS) Classless Inter-Domain Routing (CIDR) subnet, following exploit-pattern traffic to the device's management interface, suggesting exploitation of a management-plane vulnerability to gain elevated access without valid credentials. 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.
