EMC/Cisco/VMware vBlock – The Data Center Virtualization Perspective

Well the cat is well and truly out of the bag now, after several months of serious courting and getting caught behind the bike shed a few time, the worse kept secret in IT has arrived. Cisco, EMC, and VMware have entered into a joint venture arrangement called V-block, so what is it and how exactly does it affect the state of play?

NIST Cloud Computing Definitions Final

There has been great debate of what comprises the cloud, how to bound the cloud so that its easier to understand, and how to secure the cloud. Christofer Hoff of the Rational Survivabilty blog has been spear-heading quite a bit of discussion on cloud taxonomy in his attempts to wrap some thoughts around how to properly secure the cloud and everything within it. The start of this journey is the act of defining exactly what the cloud is, and is not. NIST’s document adds some more to an existing definition by defining public and private clouds.

Intrusion Protection and Detection within the Virtual Environment

Intrusion Protection Systems (IPS) differ quite a bit from Intrusion Detection Systems (IDS). An IPS is designed to modify some form of security setting when an intrusion is detected, thereby preventing the intrusion from being successful. An IDS on the other hand is just the detection component used by an IPS. Like all security tools used within a virtual environment there are four major ways to implement such devices. We will discuss later some best practices for managing a security tool. We will look at what is currently shipping over products hinted at for the future such as the OpenVSwitch, Xen Instropection API.
