Informed Infrastructure Management Is Key

The root of this challenge lies in knowledge. MSPs may need to comb through mountains of network data in a seemingly unending quest to locate critical network infrastructure assets. With too much data and uncertainty, many IT professionals adopt a one-size-fits-all approach.

This kind of uniform security treats every asset as equally valuable. And if every aspect of a network’s infrastructure is equally important, then each requires equal security monitoring. These demands, of course, are untenable.

Network infrastructures can include numerous pieces of hardware — including routers and cables — and software and network applications that include varied operating systems and firewalls. Network infrastructures also include network services such as internet connections.

Resource-savvy MSPs know to deploy their tightest security for their most critical data. But once the critical assets have been identified, what’s the best way to implement layered security? Writing for the SANS Institute, Karnail Singh suggests a four-layered network infrastructure security approach.
