Analytic 2168

Real-time monitoring of switch/router interface counters identifies a sudden spike in discarded or errored packets on an Industrial Control System (ICS)-facing interface combined with Central Processing Unit (CPU) utilization climbing above baseline, correlated with loss of reachability to downstream field devices on that segment within the same window. OT operational-fidelity gate: Alert only when a device-specific traffic/resource threshold is exceeded and the same window shows service degradation, failed polling, device alarm/restart, resource exhaustion, or malformed/out-of-spec protocol behavior. Suppress planned load tests, maintenance, network convergence/failover, and known equipment faults after operator confirmation.
