BREACH (Browser Reconnaissance and Exfiltration via Adaptive Compression of Hypertext) is a security exploit against HTTPS when using HTTP compression. This article shows several ways to deal with BREACH using Length Hiding technique with nginx’s builtin modules.
When using Cloudflare to hide IP address of the origin server (for example, to protect against DoS attacks), it is important to configure ACLs to allow connections to the origin server only from Cloudflare IPs. However, the list of Cloudflare IP ranges is not static, it changes over time. This post describes how to import this list into nginx automatically.
This article provides a configuration for nginx that successfully passes SSL Labs tests with A or A+ mark, and 100% score for all metrics (certificate, protocol support, key exchange, cipher strength).

This post presents a TLS configuration for nginx to get A+ score in HTBridge and SSL Labs tests. According to HTBridge, this configuration is compliant with PCI DSS, NIST, and HIPAA guidelines.
