Web Application Firewall

A web application firewall can be either a filter or a server plugin that controls the HTTP conversation by applying a set of rules. These rules usually include general attacks such as SQL injection and cross-site scripting (XSS).

 

To scan and block many other attacks, one can customize these set of rules to their application suitably.

Before choosing any web application firewall provider, your organization has look for two main criteria: 1. How effective are the default set of rules and 2. How easily and efficiently they can be customized. Many times the default set of rules breaks and needs modification. So it’s quite important to consider many things such as the effectiveness of logging, speeds that default rule set can handle, platforms it can support and its condition. Also, akin to any firewall it needs to be up-to-date to boost its performance.
