WAF
acronymnetworkingsecurity
Stands for: Web Application Firewall
A filter that inspects web traffic and blocks application-layer attacks.
A Web Application Firewall sits in front of an app and looks inside HTTP, stopping injection, cross-site scripting, and similar attacks that a network firewall cannot see. It is protection at layer 7, tuned to the shape of web requests rather than ports and addresses.
Also known as: waf, web application firewall, app firewall
