CloudTrail log file validation should be enabled

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
