The standard approach to securing data centers has emphasized strong perimeter
protection to keep threats on the outside of the network. However, this model is
ineffective for handling new types of threats – including advanced persistent threats
and coordinated attacks. What’s needed is a better model for data center security:
one that assumes threats can be anywhere and probably are everywhere, then acts
accordingly. Micro-segmentation, powered by VMware NSX™, not only adopts such
an approach, but also delivers the operational agility of network virtualization that is
foundational to a modern software-defined data center.
