On the last Virtualization Security podcast our guest was Robert Rounsavall, CEO of Trapezoid. Trapezoid is looking into how to alleviate supply chain security issues. In essence the security of the hardware. At many a presentation I have asked “do you trust the hardware and many times the answer is that they do another time is they do not. This depends entirely on your thoughts with respect to hardware security. But what can you do about hardware security? What is the worst that can happen if the hardware is infiltrated?

On many a Virtualization Security Podcast I tend to mention that we need greater visibility into the cloud to judge whether Cloud Service Provider security measures are good enough. But why should we bother? I am not saying we should not be concerned about a cloud’s security but that we should as tenants be concerned with clouds meeting our security, compliance, and data protection policies and requirements. Will a cloud service provider ever be able to meet a specific organizations requirements as well as the cloud service providers policies and compliance?

The 6/14 Virtualization Security Podcast we spoke about firewall placement within the virtual environment as well as storage based defense in depth. While we covered Encryption on the 5/31 podcast, in the 6/14 podcast we covered other measures when dealing with storage (which will be part of a followup post). This conversation was slightly different than all other firewall discussions, as it was about migrating from a physical environment to a virtual environment, and keeping the same firewall placements. Spurred by a customer, we sought to come to a set of guidelines to follow for defense in depth within the virtual as well as physical and hybrid cloud environments.

2011 saw a shift in how virtualization security was viewed and it showed in the way companies teamed up to address those needs. Even so, the most basic of issues still exist: The thought that once you virtualize you are more secure, and the lack of general protection for the management constructs of a virtual or hybrid environment. These two concepts have hindered adoption of virtualization security in 2011. Even so, there has been a steady shift through out the year as more and more companies talk about virtualization security. VMware has definitely lead the pack with its vShield Product line and its unified view of virtualization security. Other hypervisor vendors are also discussing virtualization security through their ecosystem if not directly. 2011 saw many companies forging their own partnerships to augment and compete in this space. Will these partnerships continue into 2012? Will virtualization security continue to be a hot area?
