Analytic 2271

Real-time monitoring identifies an Industrial Control System (ICS) vendor process making outbound connections on commonly-allowed port (e.g., 80, 443, 8080, etc.) to a destination not in the approved vendor domain list, from a host whose documented role does not require external connectivity. OT operational-fidelity gate: Alert only when the asset's documented role does not permit the connection and the destination/proxy/service is outside the approved communications profile, with process/service identity used as corroboration where available. Suppress approved vendor support, update repositories, remote operations, failover paths, and documented temporary connectivity.
