Open source spotlight: Bringing web application security to Falco with Falcoya's Nginx plugin

Falcoya, a new lightweight plugin for Falco, enhances web application security by enabling real-time analysis of Nginx access logs, allowing detection of application-layer attacks such as SQL injection, cross-site scripting, and command injection. Traditionally, Falco has been effective in monitoring runtime security across Linux hosts, containers, and Kubernetes environments but lacked the capability to inspect HTTP requests or web payloads directly. Falcoya addresses this gap by parsing Nginx log files in real-time and matching them against detection rules, providing enhanced visibility into web-layer threats. Its implementation in Go ensures minimal system overhead, making it suitable for containerized environments, while its use of Falco-style YAML allows for custom rule creation without code modification. By integrating Falcoya, organizations can extend their Falco-based monitoring workflows to include web application activity, maintaining the speed, transparency, and customizability that Falco users expect.
