Next Generation Firewalls: Restoring Effectiveness Through Application Visibility and Control

Overview Network security gateways are under siege. New threats are being launched faster than ever and are increasingly targeting application-layer vulnerabilities. At the same time user-centric and enterprise applications alike are taking advantage of commonly allowed communication ports and services to ensure their passage across security boundaries and to facilitate operation in the broadest set of networking scenarios. The result has been a steady erosion of the effectiveness of network firewalls and, consequently, the illumination of fundamental flaws in the initial design and subsequent modifications to these foundational elements of most enterprise security strategies. This paper explores a combination of ongoing and emerging factors that are exposing a variety of deficiencies with current firewall designs.
