Understanding the value of an enterprise application-aware firewall
This article is part of the October 2011 Vol. 2, No. 5 issue of Network Evolution
Firewalls have been the predominant form of security for Internet-connected networks for some 25 years now. While the technology remained largely unchanged for much of that time, more recently a new generation of "application-aware" firewalls has emerged to deal with today's application-centric threats. More on application security SANS Top 25 programming errors: Application security best practices Netsparker: Free Web application security testing tool Black Hat 2010 podcast: Mobile application security threats During this last quarter century, attackers have moved from targeting operating systems to targeting the applications that run on them, moving up the protocol stack to use protocols such as HTTP and XML to launch sophisticated attacks. These attacks are designed to circumvent the traditional access control policies enforced by perimeter firewalls. In turn, firewalls have added more functionality to be able to operate on all layers of the protocol stack, from layer 2 to layer 7, inspecting traffic and analyzing protocols...
Features in this issue
Today's enterprise application-aware firewall technology offers a host of features to manage application and Web 2.0 traffic. Expert Michael Cobb takes a look at the features and how to make the most of them.
Linking building and power management systems to converged Ethernet networks brings new security concerns.
Application-aware traffic management technology that exists today just doesn't cut it. This Fast Packet blogger would like to see session-based application-aware routing that provides visibility of session state, application behavior and bandwidth use.
Application performance monitoring tools must provide visibility to everything from storage I/O to remote end-user access and a whole lot in between. Here’s what your monitoring tools should show.
