Web application firewall (WAF) Definition

Web application firewall (WAF) is an application firewall which filters, monitors, and blocks traffic from HTML web applications. A web application firewall is deployed through a proxy and can be network-based, host-based or cloud-based. A web application firewall is distinct from a regular firewall in its ability to filter particular web applications whereas the normal firewalls function as a gateway between servers. Security flaws like SQL injection cross-site scripting, file inclusion and security imperfections can be prevented by a web application firewall. T

he firewall runs as a network appliance, inspects packets of data to analyze web application logic to filter harmful traffic.  The proxies guard the clients whereas the role of web application firewall is to protect servers. A Web application firewall is often regarded as a reverse proxy.

This web application firewall can be customized to an application. The web application firewalls follow a typical combination of a positive security model and an adverse security. But these firewalls cater to the product and service-based companies. The network-based web application firewalls are hardware-based and are installed locally. Major network-based web application firewall vendors allow deployment and configuration on large-scale.

The host-based web application firewalls, unlike the network-based, are fully integrated into the application code. These require local libraries and local servers for functioning. Cloud-hosted web application firewalls involve a simple domain name system (DNS) to redirect application traffic. The strategy allows applications to be secured and use similar profiles against application layer attacks.
