The week before VMworld on 8/25 was the Virtualization Security Podcast featuring Greg Ferro (@etherealmind), CCIE to discuss Cisco VM-FEX and its impact on virtualization and cloud security. VM-FEX is a method by which the fabric of a UCS top of rack switch is extended to the VM, but only if the VM is using VMDirectPath. So does this impact Virtualization and Cloud Security in any way?

On the 7/28 Virtualization Security Podcast, we were joined by Robert Martin of Mitre to discuss Mitre’s new CWE, CWSS, and CWRAF tools to aid in software and system security evaluation. We put a decidedly cloud based discussion around these tools to determine how they would be used by those that program within a PaaS environment, make use of SaaS, or other cloud services.

The 6/30 Virtualization Security Podcast with Simon Crosby Founder and CEO of Bromium started with a discussion of SaaS security but soon went to a discussion of Data Security. Simon left Citrix not to long ago to form a new company, Bromium, to seriously look into how the hypervisor itself can provide better security for data manipulations than it does today. But first we started off with SaaS and how you can Identify the user within a cloud. Continue reading Start with SaaS Security: End with Data Security
The 6/16 Virtualization Security Podcast started as a twitter conversation with a comment about PaaS Security where James Urquhart, Krishnan Subramanian, Rich Miller, and myself went back and forth about PaaS security and the role of the developer. It was not quite a DevOps conversation but pretty close. Rich could not join us on this Podcast but hopefully will make a future one. PaaS security appears to be dependent on two things, the provider’s security, and how it is used. Continue reading Improving PaaS Security: Get your Developers Involved
On the 6/2 Virtualization Security Podcast, Rich Mogull, an analyst for Securosis, joined us to discuss his work with the Cloud Security Alliance (CSA) to develop the two day course called the Certificate of Cloud Security Knowledge (CCSK). While this course is not about learning all the intricacies of cloud security it is about providing a level set of knowledge required to even begin to talk about cloud security.

One of the basic tenants of virtualization security is to protect the management components of your virtualization hosts by placing these all important components on a separate network. These components often include management servers such as SCOM, vCenter, XenCenter, VirtManager, etc. as well as the management appliances of your virtualization hosts. In essence, the use of a properly configured, firewalled, and monitored virtualization management network would be the simplest and most effective security measure that can be made to day within any virtual environment. A message shared by Citrix, VMware, myself, and many others.
The problem is that not everything is as black and white as security folks desire. If we implement performance and other management tools, we often need to expose part of our all important virtualization management network to others. But how do we do this safely, securely, with minimal impact to usability? Why do we need to this is also another question. You just have to take one look at the Virtualization ASsessment TOolkit (Vasto) to realize the importance of this security requirement. But the question still exists, how do you implement other necessary tools within your virtual environment without impacting usability? Which we discussed on the May 5th Virtualization Security Podcast. Continue reading Security of Performance and Management tools within the Virtual Environment
