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.
