How to Send AWS CloudTrail Logs to Microsoft Sentinel

Build a centralized AWS-to-Sentinel monitoring path for high-value AWS security telemetry.

Architecture

AWS Accounts -> CloudTrail -> Central Logging -> Integration -> Sentinel -> Analytics -> Incident

Implementation

Start with high-value use cases:

• Root activity
• IAM changes
• Access-key creation
• Trust-policy changes
• Logging changes
• Security-group changes

Protect the logging destination with encryption, restricted access, retention controls, and monitoring.

Configure the supported Sentinel AWS integration for your environment and validate authentication, permissions, ingestion, schemas, and connector health.

End-to-End Test

AWS API Call -> CloudTrail -> Sentinel -> Analytics Rule -> Alert/Incident

Create a controlled non-production event and measure the complete path.

Final Takeaway

A SIEM integration is valuable only when telemetry reliably becomes detection and response. Start small and validate before expanding.
