Hardening Nginx Reverse Proxies with Dynamic Upstreams & Rate Limiting Guards

Step-by-step blueprint for deploying hardened reverse proxies, configuring CSP headers, and mitigating brute-force and scraping bots without bloated CDNs.

## Reverse Proxy as the First Line of Defense Nginx remains one of the most battle-tested reverse proxies on earth. In this engineering guide, we walk through our standard production configuration: - Hardened SSL/TLS 1.3 ciphers with strict forward secrecy - Dynamic upstream routing for containerized microservices - Memory-efficient zone rate limiting to block API brute-forcing - Strict Content Security Policies (CSP) and security headers
