Simulate or collect telemetry
Gather event-rate, authentication and traffic-volume features and label a small holdout set for validation; keep provenance metadata for each record.
Govern security ML models. Balance alerts and analyst load.
AI governance for cybersecurity workflows organises how models are developed, validated, monitored and escalated into analyst workflows. Key governance concerns are data provenance, alert precision/recall trade-offs, human-in-the-loop review and auditable model versioning.

AI governance for cybersecurity workflows organises how models are developed, validated, monitored and escalated into analyst workflows. Key governance concerns are data provenance, alert precision/recall trade-offs, human-in-the-loop review and auditable model versioning.
A proposed extension: run anomaly detection on security telemetry and surface human-reviewable alerts with audit trails, escalation rules and model-version metadata. For any operational use, a security analyst must remain responsible for triage and response; the prototype is not suitable for automated defensive decisions without further validation and governance.
Gather event-rate, authentication and traffic-volume features and label a small holdout set for validation; keep provenance metadata for each record.
Fit an unsupervised anomaly detector on historical 'normal' data to surface outliers, and record model configuration and random seeds for reproducibility.
Measure precision, recall and false-positive rate on labelled incidents; choose alerting thresholds that match analyst capacity.
Provide model versioning, explainability summaries, audit logs for alerts, and a human-review workflow before any automated escalation.
The supplied starter synthesises numerical 'logs' (event rate, failed attempts, bytes out), fits an IsolationForest anomaly detector, adds a fit_predict anomaly label column, and prints the number of alerts and their head. It is a compact unsupervised anomaly-detection baseline on generated data, not a full governance pipeline.
logs = pd.concat([normal, suspicious], ignore_index=True)
detector = IsolationForest(contamination=0.05, random_state=42)
logs["anomaly_score"] = detector.fit_predict(logs)
alerts = logs[logs["anomaly_score"] == -1]
The code uses small synthetic numeric data and a single IsolationForest run; it does not implement governance features (auditing, model versioning, explainability, alert routing or integration with SIEM/YARA/Sigma rules). The synthetic 'suspicious' rows are not labelled real incidents, and the two-class fit_predict output (-1/1) is used as a proxy alert without calibrated thresholds or labelled evaluation.
A proposed extension: replace synthetic logs with real telemetry, record model metadata and training data snapshots, add a dashboard showing alert provenance and allow analysts to confirm/deny alerts to create a feedback loop for retraining.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
