The Virtualization Practice

Virtualization Security

Virtualization Security focuses upon end-to-end security, integrity, auditability, and regulatory compliance for virtualization and clouds. Virtualization Security starts where the cloud and virtual environments begin: the end user computing device. ...
We follow the user through the virtual and cloud stacks until they reach the application the user wishes to use to retrieve the data that is important to them. Virtualization and cloud security is implemented where there is an intersection between user, data, and application while maintain strict control of management interfaces. As such virtualization security looks into all aspects of security devices, tools, controls, and guides that impact or can be used to secure virtual and cloud environments.

Since coming out with VMware vSphere and Virtual Infrastructure Security: Securing the Virtual Environment, I have continued to consider aspects of Digital Forensics and how current methodologies would be impacted by the cloud. My use case for this is 40,000 VMs with 512 Servers and roughly 1000 tenants. What I would consider a medium size fully functioning cloud built upon virtualization technology where the environment is agile. The cloud would furthermore contain roughly 64TBs of disk across multiple storage technologies and 48TBs of memory. Now if you do not think this exists today, you were not at VMworld 2009, where such a monster was the datacenter for the entire show and existed just as you came down the escalators to the keynote session.

Virtualization Security vendors are starting to seriously investigate the possibilities of the various introspection APIs available to the hypervisors. Introspection APIs allow security groups to now investigate the security of a virtual network, virtual machine, and other components from without. In other words, why rely on an agent within the VM to protect your network, virtual machine, or components. Instead, we can use these APIs to peer into these components from without the system to be tested.

Security baselines and security health checks are an important part of any modern day infrastructure. These checks are done periodically throughout the year, usually ever quarter. In my opinion this is a good thing to check and make sure your security settings are following the guidelines that the company has set out to achieve. Here is where I do have a problem. When setting up the guidelines for the different technologies in your infrastructure it would make the most sense that the people establishing the guidelines need to fully understand the technology they are working with. After all, would you really want the midrange or mainframe group to write the policies and guidelines for the Microsoft Windows Servers in your environment?

The most recent Virtualization Security Podcast was on the subject of virtualization security for the SMB. Specifically cover the case where the customer wanting virtualization security could afford to purchase a hypervisor and perhaps one other security product. In the end the panelists came up with a list of suggestions for virtualization security for the SMB that are applicable to all levels of Virtualization. The panel looked at SMB security with an eye towards Availability, Integrity, and Confidentiality.

While at RSA Conference I visited the RSA Innovation Sandbox and noticed that three out of ten virtualization security vendors were finalists:

* Altor Networks
* Catbird Security
* HyTrust

Alto Networks won the Innovation Sandbox contest and all that goes with it. Congratulations to them, but Altor’s win is actually a win for all virtualization security players. It shows that virtualization security is extremely important to the data center as well as moving forward to the cloud.

The Cisco-VMware-NetApp (CVN) was discussed on the Virtualization Security Podcast as it pertains to Secure Multi-Tenancy (SMT). This is a major concern that was also discussed at RSA Conference 2010 within the Cloud Security Alliance Summit. The question still remains how to achieve this goal however. CVN is a very good start, but as we discussed on the podcast is missing some key elements.

HyTrust has announced Series B Financing in the amount of $10.5 Million with participation from Cisco, Granite Ventures as well as existing investors Trident Capital and Epic Ventures. This is very good news for HyTrust. While the Series B Funding was not much of a surprise given that HyTrust fits into the Virtualizaiton Security within its own niche. What is surprising is that Cisco is one of the backers of this innovative product.
