A Web Application Firewall (WAF) is a security solution designed to monitor, filter, and block HTTP/HTTPS traffic to and from a web application. By inspecting incoming traffic based on predefined security rules, a WAF helps protect web applications from attacks such as SQL injection, cross-site scripting (XSS), and other OWASP Top Ten threats. It acts as a barrier between the web application and malicious actors, ensuring the integrity, confidentiality, and availability of web services.
