name: CloudTrail Log Integrity Validation not Enabled
author: princechaddha
severity: high
description: |
Ensure CloudTrail log file integrity validation is enabled to detect unauthorized file modifications.
impact: |
Without log file integrity validation, it's harder to detect if CloudTrail logs have been tampered with, potentially hiding malicious activity.
remediation: |
Enable log file integrity validation on all CloudTrail trails to ensure the integrity and authenticity of your logs.
