What it detects

This rule identifies Windows Defender Real-Time Protection problems by matching windefend events where a feature fails (EventID 3002) or restarts (EventID 3007). Attackers may trigger or take advantage of defensive instability to impair protection, making these events important for validating endpoint security health. It relies on Windows Defender windefend telemetry for the specific event IDs and optionally filters known Network Inspection System update and service-stop reasons.
