There have been a large number of Announcements that have been made for VMworld Copenhagen with respect to virtualization and cloud security. This shows quite an interesting growth in the market, and that even 1 month apart there is still more to be announced within the virtual and cloud security spaces. There are three very interesting announcements that show further integration between vendors. Continue reading Virtualization Security Announcements: Architecture Concerns
If there was one thing I saw and heard about at VMworld, was the number of third party collaborations that were taking place. While not explicitly stated by VMware at VMworld, the show floor had many different collaborations that were taking place. This level of collaboration shows a level of maturity within the virtualization and cloud vendor ecosystems. A maturity, that shows that the vendors understand the benefits of leveraging other companies to lower their overall costs while producing better and more attractive products. Some of the collaborations I saw where purely the resale of products, while others were integrations between products. Here are some that stuck in my mind: Continue reading Collaborations abound at VMworld 2011
My pilgrimage from VMworld 2011 in Las Vegas has come to an end. In my humble opinion, this has been the week for the storage side of things with some amazing and interesting new stuff that has been released or is about to be released. There has been some really cool stuff that is working with SSD and storage. Continue reading Quick Recap of VMworld 2011
More and more is coming out about the attack from a MacDonald’s that left an organization crippled for a bit of time. The final tally was that the recently fired employee was able to delete 15 VMs before either being caught or he gave up. On twitter, it was commented that the administrator must not have been a powershell programmer because in the time it takes to delete 15 VMs by hand, a powershell script could have removed 100s. Or perhaps the ‘Bad Actor’ was trying to not be discovered. In either case, this has prompted discussions across the twitter-sphere, blog-sphere, and within organizations about how to secure from such attacks.

As a delegate for Tech Field Day 6 in Boston, I was introduced to several virtualization and performance management tools from vKernel, NetApp, Solarwinds, Embotics, and a company still in stealth mode. With all these tools and products I noticed that each was not integrated into the roles and permissions of the underlying hypervisor management servers such as VMware vCenter, Citrix XenConsole, or Microsoft System Center. This lack of integration implies that a user with one set of authorizations just needs to switch tools to gain a greater or even lesser set of authorizations. This is not a good security posture and in fact could devolve any security to non-existent. Continue reading Centralized RBAC Missing from Virtualization Management Tools
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
