Description

CloudTrail log file validation generates a digitally signed digest file containing a hash of each log that CloudTrail writes to S3. This feature helps verify whether a log file was changed, deleted, or remains unchanged after delivery, thereby enhancing the integrity of CloudTrail logs. Enabling log file validation on all trails is recommended.

Remediation

For instructions on enabling log file validation for CloudTrail, refer to the AWS CloudTrail Log File Validation Guide.
