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.
