Preventing data exfiltration in machine learning environments with Amazon SageMaker AI | Amazon Web Services
6/29/2026
This post details a three-layered security architecture implemented by iBusiness to prevent data exfiltration in machine learning environments using Amazon SageMaker AI and Amazon WorkSpaces Secure Browser. Layer 1 secures access through WorkSpaces Secure Browser by disabling file downloads/uploads, clipboard access, and printing, and routing traffic through a NAT gateway with IAM policies. Layer 2 restricts browser activity with URL allowlisting and prevents cross-account access using VPC endpoints for AWS Management Console and IAM Identity Center, along with Route 53 Resolver DNS Firewall. Layer 3 secures the SageMaker AI environment by removing direct internet access, configuring VPC endpoints for required AWS services, and restricting endpoint policies to organization-owned resources.
