SysMon Anomaly Calibration
A browser-only reproducibility demo derived from my SysMon AI project.
The Space uses precomputed Isolation Forest scores on synthetic telemetry. Training and scoring were performed offline with scikit-learn; the browser only changes the calibration threshold and recomputes the held-out metrics. This keeps the Space fully static while preserving the experimental idea being demonstrated.
Protocol
- Fit Isolation Forest on synthetic normal telemetry.
- Score a separate normal calibration window.
- Select a threshold from a requested calibration false-positive rate.
- Apply that threshold to a separate test window containing injected anomalies.
- Report spam-style minority metrics: precision, recall, F1, observed false-positive rate, and accuracy.
Important limitation
This is a synthetic methodological demonstration, not a claim of production workstation performance. The full SysMon engineering project and case study remain the canonical sources for system-level results.
