AWS CloudTrail S3 Buckets Without Access Logging

What It Does

This policy template reports any CloudTrail S3 buckets in the AWS account that do not have access logging enabled. Optionally, this report can be emailed.

S3 Bucket Access Logging generates a log that contains access records for each request made to your S3 bucket. An access log record contains details about the request, such as the request type, the resources specified in the request worked, and the time and date the request was processed. It is recommended that this logging be enabled for all CloudTrail S3 buckets to provide an audit trail.
