Web Application Firewall
A web application firewall is a security system that monitors and filters incoming and outgoing traffic to and from a web application. It helps protect the application from common web-based attacks such as SQL injection, cross-site scripting, and DDoS attacks. The firewall analyzes HTTP requests and responses, blocking any malicious traffic while allowing legitimate traffic to pass through. It acts as a barrier between the web application and the internet, helping to prevent unauthorized access and data breaches.
