|
|
|
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.
