Is Perimeter Security Really Dead?

Despite naysayers, many security experts believe perimeter defenses have relevance when deployed as a part of defense-in-depth.

Even while mobile, cloud, and software services are blurring the lines of corporate IT boundaries through deperimeterization, enterprises still continue to spend increasing amounts of security budget on perimeter protection. The question is, are they wasting their money? It's one of the most contentious questions in security -- perhaps only behind the one about the usefulness of antivirus. So it is no surprise that the answers are varied.

Hardliners, of course, have been hammering on the death of the perimeter for a long time now.

"Perimeter security is no longer relevant to enterprises. With the mobilization of the workforce, it's very hard to define the perimeter of any organization because mobile-enabled employees are connecting to the network from all over the world on devices of their choosing," says Thevi Sundaralingam, vice president of product management at Accellion. "Next-gen security needs to focus keeping content safe, not on defining a network perimeter."

Go on Offense
When I think of permiter defense, the first things that comes to mind are not the lackluster security software and appliances used to safeguard the treasure troves of the corporate world. 

I think of attack dogs inside a chain-link fence -- more specifically, Dobermans that leap, bark, growl, run (fast) and -- if you give the a chance -- chew your leg off.  

Corporate security needs to be more like attack dogs and less like library lions.  I know what you're thinking "you can't track people over the Internet."  Here's what I'm thinking: "It's time to change that." 

Grrrrrrrr....
