Ensure the bucket ACL does not grant 'Everyone' READ_ACP permission [read bucket ACL]
Description
The S3 bucket ACL gives 'Everyone' permission to read the bucket ACL. It is best practice to restrict READ_ACP permission to only principals who require it.
Note: S3 buckets created with the default/recommended AWS settings have ACLs disabled and will therefore be compliant with this policy.
Remediation
Perform the following to revoke READ_ACP permission for 'Everyone':
Sign in to the AWS Management Console
Select Services
Select S3
Select the bucket to change
Navigate to Permissions
Navigate to Access Control List and select Edit
Against Everyone (public access), uncheck 'Read' under Bucket ACL
Select Save changes
Repeat steps 4-8 for each bucket requiring updated permissions
