While firewalls have always been an important part of security, new innovations in firewall technology have allowed the application of deep packet inspection (DPI). This development is important because of the increased use of sophisticated new security threats.

Hackers are looking to delve deeper into database applications, financial reporting tools, ERP systems and the like to find the most intimate and potentially valuable information. Further, if a hacker's goal is to disrupt or damage, then loss of service to a mission-critical application is a sure win for the dark side.
