About This Architecture

Zero-trust S3 architecture isolates an Application Server (t3.medium) in a private subnet with no internet gateway, enforcing encrypted access through a VPC Gateway Endpoint. The IAM Role grants least-privilege access to an S3 Bucket encrypted with a KMS Customer Managed Key, while a bucket policy explicitly denies all requests except from the app role and blocks public access entirely. Security Hub aggregates findings from GuardDuty threat detection, Macie data classification, AWS Config compliance rules, CloudTrail API audit logs, and Wiz CSPM monitoring to provide unified visibility. Fork this diagram on Diagrams.so to customize IAM policies, add additional VPC endpoints, or integrate your own CSPM tooling for multi-account deployments.

How do I design a secure AWS S3 architecture with no public access using VPC endpoints and IAM roles?

Deploy an Application Server in a private subnet with no internet gateway, attach an IAM Role with least-privilege S3 permissions, and route traffic through a VPC Gateway Endpoint to an encrypted S3 Bucket with a bucket policy that denies all access except the app role. Integrate Security Hub to aggregate findings from GuardDuty, Macie, Config, and Wiz for unified threat detection and compliance m
