Web Application Firewall (WAF)
A Web Application Firewall (WAF) is a security device that monitors and filters HTTP traffic between a web application and the internet. WAFs are designed to protect web applications from a variety of attacks, including cross-site scripting (XSS), SQL injection, and denial-of-service (DoS) attacks.
WAFs work by inspecting HTTP traffic and identifying patterns that are associated with attacks. When a WAF identifies a suspicious pattern, it can take a variety of actions, such as blocking the traffic, logging the traffic, or rewriting the traffic.
