On 15 May 2023, a change will be released for the listed Rules that check if object-level logging is enabled for S3 buckets. 

Currently, S3 buckets in Stax-managed member accounts will fail the check even when the required CloudTrail S3 data event logging is enabled, because Stax follows AWS best practices and configures CloudTrail at the Organization-level, not within every individual member account.

After the change, this Rule will detect when S3 data event logging is enabled on CloudTrail trails configured in member accounts as well as when configured on Organization-level CloudTrail trails.

By default, Stax does not configure S3 object-level logging for Stax-managed accounts. An S3 bucket with a high workload could quickly generate thousands of logs in a short amount of time, resulting in increased AWS costs.
