Securing Quick access from corporate networks with AWS PrivateLink
aws ·
This AWS technical guide details how to secure Amazon Quick access from corporate networks by preventing traffic from traversing the public internet. It explains the distinction between VPC endpoints, which handle user-facing console and API traffic, and VPC connections, which allow Quick to privately fetch data from on-premises databases and internal APIs. The walkthrough outlines the necessary prerequisites, including an existing Direct Connect or VPN link, and provides step-by-step instructions for configuring interface VPC endpoints using AWS PrivateLink. Administrators are guided through setting up DNS resolution via Route 53 private hosted zones and defining restrictive endpoint policies to limit access to specific accounts or organizations. For data retrieval, the article describes creating VPC connections that place Elastic Network Interfaces within the customer's VPC, enabling secure communication with private resources. To ensure comprehensive security, the guide recommends enforcing IP and VPC endpoint restrictions to block unauthorized public access while integrating AWS IAM Identity Center for robust identity federation and role-based access control. Finally, it covers monitoring strategies using VPC Flow Logs and CloudWatch, along with cost considerations for maintaining this private architecture.
