There is nothing like fully understanding the protections inherent within your vNetwork and the Roles and Permissions you can set within the virtualization management tool suites to ensure your vNetwork is secured, audited, and monitored for issues. Just like you do now within the pNetwork. Unlike the pNetwork, the vNetwork provides a certain amount of introspection and capability that is missing from a pNetwork, and this will also help with security.

During the Virtualization Security Podcast on 5/13, IBM’s David Abercrombie joined us to discuss IBM’s Virtualization Security Protection for VMware (VSP) which contains several exciting uses of the VMsafe API for VMware vSphere. These being:
* Network: Network Monitoring, Firewall, Access Control, and a Protocol Analysis Module
* Memory: Rootkit Detection

I recently spoke at the InfoSec World 2010 Summit on Virtualization and Cloud Security and also attended the main conference sitting in on many Virtualization discussions. Perhaps it was the crowd, which was roughly 30-40% auditors. Perhaps it was the timing as SourceBoston was also going on, as well as CloudExpo in NY. But I was surprised to find that people are still ‘just starting’ to think about Virtualization Security. Since I think about this subject nearly every day, this was disappointing to me at best. I found ideas around virtualization security ranging from:
* Virtualization Security is not part of an architecture/design, what do I bolt on?
* My Physical Security will work
* Virtual Environments NEED More security than physical environments
* There are no new threats, so why have something more
* Security is a hindrance

The most recent Virtualization Security Podcast was on the subject of virtualization security for the SMB. Specifically cover the case where the customer wanting virtualization security could afford to purchase a hypervisor and perhaps one other security product. In the end the panelists came up with a list of suggestions for virtualization security for the SMB that are applicable to all levels of Virtualization. The panel looked at SMB security with an eye towards Availability, Integrity, and Confidentiality.

Brad Hedlund of Cisco asked the question, should the physical network security policy be different than the virtual network security policy? The answer is obviously no, but why are they treated separately? I and other have pushed the concept that to gain performance, redundancy, and security that you should use multiple network links to your virtualization host to separate traffic. However, does this really give you security?
