Understanding and Selecting an Enterprise FirewallBy Mike Rothman
What? A research report on enterprise firewalls. Really? Most folks figure firewalls have evolved about as much over the last 5 years as ant traps. They’re wrong, of course, but people think of firewalls as old, static, and generally uninteresting. But this is unfounded. Firewalls continue to evolve, and their new capabilities can and should impact your perimeter architecture and firewall selection process. That doesn’t mean we will be advocating yet another rip and replace job at the perimeter (sorry, vendors), but there are definitely new capabilities that warrant consideration – especially as the maintenance renewals on your existing gear come due.
We have written a fairly comprehensive paper that delves into how the enterprise firewall is evolving, the technology itself, how to deploy it, and ultimately how to select it. We assembled this paper from the Understand and Selecting an Enterprise Firewall blog series from August and September 2010.
