AWS recently introduced the IAM Access Analyzer, a tool that uses automated reasoning to identify insecure access to AWS resources such as S3 Buckets and Lambdas. Simultaneously, Pulumi launched CrossGuard, a policy-as-code solution that validates policies during deployment. The integration of these two services enhances security by combining IAM Access Analyzer's ability to detect access issues with CrossGuard's capability to flag and prevent insecure deployments in real time. By implementing CrossGuard policy packs alongside IAM Access Analyzer, users can enforce best practices for AWS resources, preventing common security pitfalls like public-read access to S3 Buckets. The collaboration between these services is designed to quickly identify and rectify security vulnerabilities at deployment time, thus reducing the risk of costly mistakes. This early-stage integration demonstrates how combining innovative tools can advance infrastructure security, encouraging users to explore policy as code with open-source resources.
