What is a Web Application Firewall?

An online application's security is enhanced by a WAF (web application firewall) which filters and monitors HTTP traffic between a web application and the Internet. Typically, it defends online applications against threats like SQL injection, file inclusion, cross-site scripting (XSS), and cross-site forgery. Any online business that needs to handle sensitive customer data securely might benefit greatly from a WAF. In order to protect their online applications from sophisticated and targeted assaults that could lead to fraud or data theft, businesses often employ a WAF.
