Abstract
Practices that could significantly improve application security by integrating knowledge about an application’s specific security needs into elements of the IT security infrastructure are often overlooked. This document describes one of the many potential topic areas involving the integration of business applications into a supporting IT security infrastructure. Application firewalls attempt to use application-specific knowledge to improve the perimeter defense that the security infrastructure provides.
