The Porous Perimeter – Is perimeter protection dead?

by Juniper Employee on 10-28-2008 04:10 PM - last edited on 10-29-2008 09:58 AM

With our morning coffee, most of us have grown accustomed to opening the paper and reading about yet another gargantuan organization that suffered a devastating loss due to a security breach. The question that begs to be asked is whether we are any better off than we were 10 years ago? Are our organizations any safer from the evil that looks to sneak into our networks and do damage?

For certain, the types of attacks have grown in sophistication, and have changed in methodology, purpose and operation. At the same time, our networks have changed. Because interconnected networks are a prerequisite for doing business, our networks have become porous.  We allow a multitude of people onto our networks including partners, subcontractors, and guests. How is it possible to have perimeter-based protection if we don’t really know where the perimeter starts or ends? Do we need to re-evaluate our security posture because perimeter protection is dead?

Over the past five years, the sheer number of security incidents has decreased dramatically. While we have not eradicated bad things from finding their way to our network, perimeter protection plays a key role in this precipitous drop.

Security will undoubtedly remain a cat and mouse game between the hacker and security professional. Some hacking attempts will work and many will be stopped.  There is no silver bullet when it comes to security; it takes a multi-faceted approach that leverages information and collaborates to root out the newest threats that are just over the horizon.

No need to initiate CPR on the perimeter-based approach just yet, for it is just another weapon in our arsenal that effectively stops the bad guys from compromising our network and our business.

Stay tuned for our next discussion where we will discuss the evolution of the attack and what the hacker is after in your network; your greatest asset may be at risk.
