AWS Security Blog Optimize AWS Config for AWS Security Hub to effectively manage your cloud security posture AWS Security Hub is a cloud security posture management service that performs security best practice checks, aggregates security findings from Amazon Web Services (AWS) and third-party security services, and enables automated remediation. Most of the checks Security Hub performs on AWS resources happen as soon as there is a configuration change, giving you nearly immediate visibility of non-compliant resources in your environment, compared to checks that run on a periodic basis.
