The value of a WAF comes from the ease and speed in which policy modifications are implemented, allowing a faster response to various attack vectors rate-limiting can quickly be implemented during a DDoS attack by modifying WAF policies. WAFS comes in different forms, such as an appliance, software, or as-a-service. It helps secure business-critical web applications from a wide range of threats, including OWASP Top 10. The reverse-proxy also acts as an intermediary, only to protect the app’s web server from potentially malicious clients. Web Application firewalls (WAF) A WAF protects the network against malicious traffic. Just like a proxy server will act as an intermediary and protect a client’s identity, a WAF operates similarly but in a reverse fashion, which is called a reverse-proxy.

These policies help protect against application vulnerabilities by determining the malicious traffic from the safe traffic then filtering out the malicious traffic. It does this through a set of policies, which are merely rules the WAF operates through.

A web application firewall (WAF) protects web apps by monitoring, filtering, and blocking malicious HTTP/S traffic that is traveling to a web application preventing unauthorized data from exiting the app. What is WAF Website Application Firewalls are software that intercepts and monitors website traffic while blocking hackers and malicious users.
