Simplifying AWS defense with Microsoft Sentinel UEBA

Learn how Microsoft Sentinel UEBA helps defenders distinguish benign AWS activity from attacker behavior by enriching raw CloudTrail logs with clear, binary behavioral signals derived from baseline user, peer, and device behavior patterns.

In this article Under the hood: The tables Traditional vs. new approach Real-world attack scenarios: Microsoft Sentinel UEBA in action Practical implementation: Getting started Limitations and constraints From raw logs to behavioral context References Learn more With the expansion of Microsoft Sentinel UEBA (User and Entity Behavior Analytics) into new data sources , spanning multi-cloud (AWS, GCP), identity providers (Okta), and authentication logs (MDE DeviceLogon, Microsoft Entra ID Managed Identity, Service Principal sign-ins), defenders can now detect behavioral anomalies across hybrid environments from a single place.

We’ve also expanded AWS coverage with more anomalies, enrichments and insights, so CloudTrail events now arrive with more built-in context at ingestion time. This lets defenders triage suspicious activity faster without building and maintaining large baselines in KQL.
