NYDFS-Compliant VPC Private Subnet Proxy Deployment

Cold servers sit in silence until the first packets arrive. By then, your compliance perimeter must already be locked. The NYDFS Cybersecurity Regulation demands it: secure systems, encrypted data, access controls, and auditable logs—implemented without delay or gap.

For teams deploying a VPC private subnet proxy, these requirements become more than theory. NYDFS rules under Part 500 require limiting external connections, monitoring privileged accounts, and segmenting systems to reduce breach scope. A private subnet inside your Virtual Private Cloud isolates sensitive workloads. Routing outbound traffic through a hardened proxy enforces policy at the edge before it reaches the internet.

A compliant deployment starts with architecture. Place application nodes in a private subnet with no public IPs. Route all traffic through a proxy in a public subnet that uses strict ACLs and security groups. Enable TLS termination only at the proxy layer. Log every connection, packet filter decision, and failed auth attempt for retention in secure storage, aligned with NYDFS 500.06 audit trail rules.

VPN tunnels or Direct Connect can bridge on-prem systems while preserving segmentation. IAM roles must follow least privilege; map them directly to proxy policies. Integrate your proxy with a SIEM for continuous monitoring under NYDFS 500.05 requirements. Base image builds should be patched and scanned before deployment. No exceptions.

To verify controls, run network flow captures in staging before production cutover. Test failover scenarios for proxy nodes. Ensure your incident response process includes proxy rule review to close suspicious channels fast.

NYDFS compliance is not just paperwork. It is architecture decisions set in stone before an attack arrives. A correctly deployed VPC private subnet proxy is both shield and scalpel—reducing attack surface, enforcing traffic policy, and meeting every clause of the regulation.
