Securing The Network From The Inside Out

by Paul Stamp, Robert Whiteley

with Laura Koetzle, Benjamin Gray


Executive Summary (This is a document excerpt)

As any security pro will tell you, the network perimeter is getting harder and harder to define, let alone defend. Moreover, those who have authorized access to internal resources are often far more dangerous than those who need to breach a perimeter firewall to get inside the network. Companies should adopt a twofold strategy of secure design and threat protection. How? By constructing a security life cycle that evaluates, assigns, segments, and monitors the network, according to security policies.
