“The modern data center is a distributed mix of bare metal and virtualized resources residing in public and private clouds. Because it is a treasure trove of proprietary, sensitive information and represents major capital value for a company, the data center becomes “big game.” It’s a tempting target for attack, whatever the arena: financial, manufacturing, healthcare, utilities, governmental, education, service provider, or others.
The steady migration of applications and workloads into modern data centers make them a challenge to protect. Exploding amounts of “east-west” (server-to-server) traffic, with hundreds and even thousands of sprawling virtual machines (VMs) inside data center and cloud environments — makes the scale of the challenge enormous. Furthermore, applications running on virtual servers are subject to the same manner of threats as those running on dedicated servers, but decreased visibility in virtualized and cloud environments raises the risk of intrusion substantially.”
