Web Application Firewall (WAF)

As a first line of defense, we can use a Web Application Firewall (WAF). Basically a WAF protects web apps/APIs by inspecting HTTP requests. It acts at the layer 7 (Application Layer of the OSI Model) and it behaves like a reverse proxy with policies and rules attached to it to protect malicious requests, preventing them to flow to our servers or services.
