Reverse Proxy Security

Definitions

1. The security of a reverse proxy layer that sits in front of backend services, handling tasks such as TLS termination, routing, authentication integration, filtering, and header management. Reverse proxy security matters because mistakes there can expose internal apps, break trust boundaries, or create bypasses across many services at once.

   In plain English: Security for the front-end proxy layer that stands between users and backend services.

   Example: "The issue was not in the app code at all but in reverse proxy security: a misrouted path exposed the internal admin interface through the public gateway."
