Collect representative telemetry
Gather IAM-related logs (auth events, role changes, API calls) and annotate a small set of confirmed incidents for evaluation.
Analyse IAM permission risk. Flag anomalous activity.
IAM permission risk analysis seeks unusual access patterns or privilege misuse by modelling telemetry from authentication and authorization events. Key issues include class imbalance, evolving baseline behaviour, correlated features (many events per principal) and the need for human verification of flagged alerts.

IAM permission risk analysis seeks unusual access patterns or privilege misuse by modelling telemetry from authentication and authorization events. Key issues include class imbalance, evolving baseline behaviour, correlated features (many events per principal) and the need for human verification of flagged alerts.
A proposed application for security operations teams: surface anomalous sessions or permission misuse candidates for analyst triage, with humans confirming and escalating serious incidents. Because this is a security-sensitive domain, a human reviewer should remain in charge and the prototype must not be used for automated enforcement.
Gather IAM-related logs (auth events, role changes, API calls) and annotate a small set of confirmed incidents for evaluation.
Aggregate per-entity features such as events per minute, failed attempts and bytes transferred, and create a held-out labelled set for testing.
Fit an IsolationForest or other unsupervised detector on normal data only, tune contamination to control analyst workload, and record alert counts.
Have analysts inspect alerts, measure precision and recall on labelled incidents, and refine features and thresholds before deployment.
The supplied starter creates synthetic 'normal' and 'suspicious' numeric log features, concatenates them, fits an IsolationForest, uses fit_predict to mark anomalies, and prints the number of alerts plus a preview of flagged rows. It does not parse IAM permission fields or use real access-control data.
detector = IsolationForest(contamination=0.05, random_state=42)
logs["anomaly_score"] = detector.fit_predict(logs)
alerts = logs[logs["anomaly_score"] == -1]
print(PROJECT_NAME)
print("Alerts generated:", len(alerts))The starter uses simulated numeric features generated from random distributions rather than real IAM permission or access-control records. The IsolationForest is applied to these contrived features, so the script demonstrates anomaly-detection mechanics but does not validate detection of real permission misuse or produce calibrated risk scores for IAM policies.
A proposed extension: ingest real IAM logs, add entity-aware features (user, role, resource), persist alerts to a simple API or queue, and collect analyst feedback to retrain or tune thresholds.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
