A web application firewall is an important piece for any person or organization hosting web-based applications, specifically if compliancy issues or concerns are involved – like payment card industry (PCI) data, for example.

While you may be familiar with standard firewalls: stateful inspection, even next-gen firewalls, Nuspire Network’s CTO Matt Corney said a web application firewall is a truly different type.

“[A WAF is] operating specifically to look for things like cross-site scripting attacks, SQL injection attacks, attacks within your web infrastructure,” Corney said.

Corney continued to explain that a WAF allows users access to virtual patching and the ability to protect an application without necessarily having to rely on developers to fix those bugs.

“Ultimately, it’s going to help you with PCI 6.6 and data security standards from a compliancy perspective,” Corney said.

There are a few aspects of a WAF that require caution when deciding on the right solution for your organization. Typically, a WAF will provide SSL decryption and has the ability to see everything that is occurring, which could cause performance issues if not properly implemented.

“There’s a couple different ways of deploying that type of technology … you want to look at how you’re going to use it – so especially in large organizations that have lots of certificates for SSL certificates for web servers … things can get deep very quickly,” Corney said.

“We certainly have the capability to assist with such things and ultimately, if you’re not utilizing some of this technology today, you certainly should be.”
