Ensure CloudTrail S3 bucket is not publicly accessible
The S3 bucket storing CloudTrail logs must not be publicly accessible. Public access could expose sensitive API activity.
Security Impact
Public CloudTrail buckets expose all API activity, including sensitive operations and potentially security credentials.
How to Remediate
Enable S3 Block Public Access on the CloudTrail bucket. Review and remove any bucket policies that allow public access.
