Naxsi is an open-source Web Application Firewall implemented as an Nginx module that defends against attacks like SQL injection, XSS, CSRF and file inclusion by scoring unexpected/‘unusual’ characters in HTTP requests rather than matching signatures. It includes a learning/whitelist mode where you crawl your site to generate rules to reduce false positives, and the talk covers both the module’s design/development within Nginx and practical usage/feedback.
