What is WAF (Web Application Firewall)?
A WAF sits between users and web applications, inspecting HTTP requests and responses for malicious patterns. It protects against SQL injection, cross-site scripting (XSS), file inclusion, and other web application attacks. WAFs can operate in block mode (preventing malicious requests) or detect mode (logging without blocking). While WAFs provide an important layer of defense, they should complement — not replace — secure coding practices and regular vulnerability scanning.
