AWS Security Hub now integrates with AWS Identity and Access Management (IAM) Access Analyzer. IAM Access Analyzer is an IAM feature that that makes it simple for security teams and administrators to check that their policies provide only the intended access to resources. The IAM Access Analyzer integration with Security Hub will send findings to Security Hub when policies allow public or cross-account access to resources. Security Hub will automatically enable this integration if you are already using IAM Access Analyzer, and you will begin receiving findings from IAM Access Analyzer without any action needed on your end. To learn more, visit the Integration page in the Security Hub console and click on the “Configuration” link for IAM Access Analyzer.
