AWS Config rules and conformance packs provide information about whether your resources are compliant with configuration rules you specify. They will evaluate resource configurations against the AWS Config rules either periodically or upon detecting configuration changes, or both, depending upon how you have configured the rule. They do not guarantee that resources will be compliant or prevent users from taking non-compliant actions. They can be used, however, to bring a non-compliant resource back into compliance by configuring appropriate remediation actions for each AWS Config rule.
