Simulate or ingest telemetry
Collect structured features from logs or network flows and ensure timestamps and entity identifiers are preserved; synthetic data can be used for initial experiments.
End-to-end AI security platform. Prioritise analyst investigation.
Security operations platforms use telemetry such as logs, network flows and authentication events to detect suspicious behaviour. Important issues include noisy features, class imbalance, concept drift, and the need to present explainable alerts so human analysts can investigate.

Security operations platforms use telemetry such as logs, network flows and authentication events to detect suspicious behaviour. Important issues include noisy features, class imbalance, concept drift, and the need to present explainable alerts so human analysts can investigate.
A possible application: triage telemetry to surface candidate incidents for human analysts, reducing manual log inspection. This project provides a small anomaly-detection baseline; any real operational use must keep a human reviewer in the loop and undergo risk assessment before deployment.
Collect structured features from logs or network flows and ensure timestamps and entity identifiers are preserved; synthetic data can be used for initial experiments.
Fit an unsupervised or semi-supervised model such as Isolation Forest on features representing normal behaviour and reserve fresh data for validation.
Review generated alerts with domain experts to confirm true incidents and record false positives for iterative improvement.
Define escalation workflows, alert thresholds, audit logs and continuous monitoring for drift, latency and input quality.
The supplied starter creates synthetic numeric telemetry (events_per_minute, failed_attempts, bytes_out_mb), concatenates normal and suspicious samples, fits an IsolationForest and prints rows flagged as anomalies. It is a compact demonstration of unsupervised anomaly detection rather than a full end-to-end platform.
"failed_attempts": rng.poisson(12, 15),
"bytes_out_mb": rng.normal(180, 30, 15),

)
logs = pd.concat([normal, suspicious], ignore_index=True)
detector = IsolationForest(contamination=0.05, random_state=42)
logs["anomaly_score"] = detector.fit_predict(logs)The starter uses small synthetic numeric arrays rather than real security logs; it does not include timestamps, entity/context fields, labelled incidents, feature engineering, evaluation metrics against a labelled test set, experiment tracking, an API, or explainability for alerts. The single IsolationForest fit on synthetic data cannot validate production performance or operational readiness.
A proposed extension: ingest real telemetry, use unsupervised detection plus supervised models trained on analyst-labelled incidents, surface ranked alerts in a dashboard and allow analysts to label outcomes for continuous 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.
