How to Find AWS CloudTrail Trails with S3 Bucket Access Logging Disabled

Server access logs can assist you in security and access audits, help you learn about your customer base, and understand your Amazon S3 bill.


This security check is part of the CIS Amazon Web Services Benchmarks and is rated severity medium.


This guide assumes that you have already installed and configured Resoto to collect your AWS resources.


  1. Execute the following search command in Resoto Shell or Resoto UI:

    > search is(aws_cloud_trail) --> is(aws_s3_bucket) and bucket_logging.target_bucket==null
    ​kind=aws_cloud_trail, ..., region=resoto-poweruser
    ​kind=aws_cloud_trail, ..., account=poweruser-team
  2. Pipe the search command into the dump command:

    > search is(aws_cloud_trail) --> is(aws_s3_bucket) and bucket_logging.target_bucket==null | dump
    ​ id: /aws/cloudtrail/123
    ​ name: some-name
    ​ ctime: '2022-12-05T22:53:14Z'
    ​ kind: aws_cloud_trail
    ​ age: 2mo28d

    The command output will list the details of all non-compliant aws_cloud_trail resources.


  • Ensure that S3 buckets have logging enabled. CloudTrail data events can also be used in place of S3 bucket logging. If that is the case, results may include false positives.

Please refer to the AWS CloudTrail documentation for details.
