name: CloudTrail Duplicate Log Avoidance
author: princechaddha
severity: medium
description: |
Ensure CloudTrail logging is configured to prevent duplicate recording of global service events across multiple trails.
impact: |
Duplicate log entries can lead to increased storage costs and complicate log analysis and anomaly detection efforts.
remediation: |
Configure only one multi-region trail to log global service events and disable global service logging for all other trails.
