WAF

Web Application Firewall

Definition

A WAF monitors, filters, and blocks HTTP traffic between the internet and web applications. It protects against common attacks like SQL injection, XSS, and file inclusion by inspecting requests against a set of rules.

WAFs can operate at the network edge (cloud WAF) or as a reverse proxy in front of application servers.
