WAF
A specialised firewall that protects a website from attacks such as code injection.
A WAF (web application firewall) filters the traffic between users and a website to block malicious requests. Unlike a classic firewall, it understands how sites work and targets attacks such as SQL injection. It helps, in particular as a temporary workaround for a flaw, but it does not replace a well-coded, up-to-date site.
