Starting today, remediating non-compliant resources with AWS Config rules is available in Canada West (Calgary) Region. This feature gives you the ability to associate and execute remediation actions with AWS Config rules to address noncompliant resources. You can choose from a list of available remediation actions. For example, you can create an AWS Config rule to check that your Amazon S3 buckets does not allow public read access. You can then associate a remediation action to disable public access for noncompliant S3 buckets.
