AWS Config

AWS Config is a fully managed cloud security posture and configuration compliance service that continuously assesses, audits, and evaluates the configurations of resources across Amazon Web Services environments. The platform records configuration changes over time and evaluates them against predefined or custom rules, providing security engineers and compliance teams with continuous visibility into resource relationships, compliance states, and configuration history across the cloud infrastructure.

The service operates by capturing detailed configuration items whenever an AWS resource is created, modified, or deleted, generating an immutable timeline of changes and dependencies. AWS Config Rules enable organizations to enforce governance baselines, verifying that resources adhere to organizational policies such as mandatory encryption, restricted security group rules, and tag enforcement. AWS Config Conformance Packs allow teams to bundle collections of rules and automated remediation actions into single deployable compliance packages aligned with industry standards such as NIST 800-53, CIS Benchmarks, and PCI DSS. Furthermore, integrated with AWS Systems Manager, Config can trigger automated remediation runbooks to correct non-compliant resources instantly without manual intervention.

Key enterprise use cases include continuous cloud security posture management (CSPM), configuration change auditing, regulatory compliance reporting, security drift detection, and automated resource remediation. By maintaining a complete operational record and validating resource state against compliance baselines, AWS Config ensures organizations sustain strong governance across multi-account cloud environments.
