Is it possible to use a Cloud Framework to better secure your datacenter? Does cloud technologies provide a secure framework for building more than just clouds? We all know that virtualization is a building block to the cloud, but there may be a way to use cloud frameworks to first secure your datacenter before you launch a private, public, or hybrid cloud. In essence, we can use tools like vCloud Director to provide a more secure environment that properly segregates trustzones from one another while allowing specific accesses.
Storage Security is not only about Encryption, which is just one aspect of Storage Security requirements for the virtual and cloud environments. It is also about increasing defense in depth and knowledge of what is touching your storage environment. As well as providing security around those touch points and to a great extent auditing and protecting the data residing within the storage devices regardless of where the devices live: within the virtual environment or within a cloud.
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.
The 3/8 Virtualization Security Podcast held a discussion on the happenings as the 2012 RSA Conference in San Francisco as well as a discussion of the features of Bitdefender’s entry into the virtualization and cloud space with their SVE product. RSA Conference high lights not just those security tools for the virtualization and cloud spaces but the entire industry and each year there is always a common theme. Was there one this year? Was there any surprises at the conference?
Virtualization and Cloud Security architects, pundits, and writers like myself often talk about protecting the data within the virtual and cloud environments. However, in order to protect that data we need to be able to determine how the data will be used, accessed, modified, and eventually removed. So, how can we understand data security without understanding the application around it. But there is an even more fundamental problem, how do we define the application and the security measures we should take?
I and others look at Virtualization Security constructs with an eye towards Cloud Security, but they are not necessarily the same. Granted for some clouds, virtualization security can lead to cloud security but this really depends on how the cloud’s architecture. Even so, what we know from Virtualization Security WILL apply to Cloud Security and will be the basis for best practices. But you say, my cloud does not use Virtualizaiton? Ah ha, I say, but it is still a cloud? And that implies there are similar security concerns. This was the discussion on the 1/26 Virtualization Security Podcast.
