WAF
Web Application Firewall — A security control that filters, monitors, and blocks HTTP traffic to and from a web application, defending against common attacks like SQL injection and cross-site scripting at the application layer. Unlike a traditional network firewall, a WAF inspects the content of web requests rather than just ports and protocols.
