AWS Identity and Access Management Access Analyzer is a new capability for security teams and administrators to validate that resource policies only provide the intended public and cross-account access. IAM Access Analyzer uses automated reasoning, which applies logic and mathematical inference to inspect resource policies. We will demonstrate how to use IAM Access Analyzer to identify resource policies that don't comply with your organization's security requirements and then proactively protect resources from unintended access. Learn how Millennium Management uses IAM Access Analyzer across their company to analyze policies associated with Amazon S3 buckets, AWS KMS keys, and more.
