Description: Checks if Amazon Simple Storage Service (Amazon S3) Buckets allow user permissions through access control lists (ACLs). The rule is NON_COMPLIANT if ACLs are configured for user access in Amazon S3 Buckets.
Trigger type: Configuration changes
AWS Region: All supported AWS regions
How to Resolve Manually
This config rule evaluates if a S3 Bucket is configured to grant user permissions through ACLs. If a bucket is found with user permissions configured via ACLs, the rule will be marked as non-compliant.
To resolve this, go to Amazon S3 service, look for the desired bucket and click on the name to edit. Once there, click on Permissions tab, find the Access control list (ACL) card and click on Edit button to edit permissions. At this point you should disable the List and Read permissions for the Everyone (public access) group. See the following picture as reference:
