Conformance packs help you manage compliance of your AWS resource configuration at scale (from policy definition to auditing and aggregated reporting) using a common framework and packaging model. Conformance packs are integrated with AWS Organizations. Using conformance packs as your compliance framework, you can package a collection of AWS Config rules and remediation actions into a single entity (known as a conformance pack) and deploy it across an entire organization. This is useful if you must quickly establish a common baseline for resource configuration policies and best practices across multiple accounts in your organization in a scalable and efficient way.
Conformance packs also provide compliance scores. A compliance score is a percentage-based score that helps you quickly discern the level to which your resources are compliant for a set of requirements that are captured within the scope of a conformance pack. A compliance score is calculated based on the number of rule-to-resource combinations that are compliant within the scope of a conformance pack. For example, a conformance pack with five rules applying to five resources has 25 possible rule-resource combinations. If two resources are not compliant with two rules, then the compliance score would be 84%, indicating that 21 out of 25 rule-resource combinations are currently in compliance. Also, compliance scores are emitted to Amazon CloudWatch metrics, which create tracking over time. Compliance scores offer a consistent measurement to track remediation progress, perform comparisons across different sets of requirements, and show the impact that a specific change or deployment has on your compliance posture.
