Security of Performance and Management tools within the Virtual Environment

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?

Harris Trusted Cloud – Closing the Gap

On the 4/7/2011 Virtualization Security Podcast, we were joined by Wyatt Starnes of Harris Corporation. Wyatt is the Vice President of Advanced Concepts of Cyber Integrated Solutions at Harris. What this means, is that Wyatt is one of the key folks of the Harris Trusted Cloud initiative. Trust is a funny word, and we have written about that in the past. Harris’ approach is unique in that they are attempting to ensure integrity of all components of the cloud down to the code level, not just the network with their target being the hosted private cloud and NOT the secure multi-tenant public cloud.

vCloud Security

On the 2/24 Virtualization Security Podcast we were joined by Davi Ottenheimer and Michael Haines of VMware to discuss vCloud security. This is of quite a bit of interest to many people these days. As VMware adds more and more Cloud functionality, how to secure the environment is becoming more and more important. The podcast started with the question what aspects of the cloud do customers want secured. The answer was intriguing to say the least.

TPM/TXT Redux

On the third Virtualization Security Podcast of 2011 we were joined by Charlton Barreto of Intel to further discuss the possibility of using TPM/TXT to enhance security within the virtual and cloud environments. We are not there yet, but we discussed in depth the issues with bringing hardware based integrity and confidentiality up further into the virtualized layers of the cloud. TPM and TXT currently provide the following per host security:

Knowing where your Data is: Backup Security

On the second Virtualization Security Podcast of 2011, we had Doug Hazelman of Veeam as our guest panelist to discuss backup security. Since most of backup security relies on the underlying storage security, we did not discuss this aspect very much other than to state that the state of the art is still to encrypt data at rest and in motion. What we did discuss is how to determine where your data has been within the virtual or cloud environment. This all important fact is important if you need to know what disks or devices touched your data. An auditing requirement for high security locations. So we can take from this podcast several GRC and Confidentiality, Integrity, and Availability elements

Cisco Pushing More vNetwork into Hardware

In the first Virtualization Security Podcast of 2011, we had Brad Hedlund with us once again. Not to talk about the Cisco Virtualization Security Gateway (VSG), but about the security of what I call physical-virtual devices that provide network virtualization within the hardware. Or what Brad Called Network ID Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere.
