The Virtualization Security Podcast on 8/5 was all about VMware vShield Zones and how the currently beta version will provide defense in depth, be a lever to achieve Secure Multi-Tenancy, and its impact on the virtualization security echo system. Dean Coza, Director of Product Management for Security Products at VMware joined us to discuss the vShield Zones Beta which consists of 3 parts given names and a nameless third part that was hinted at and we shall see more about at VMworld.
In the End-to-End Virtualization Security Whitepaper we review various aspects of server security with an eye to determining how the products would work together to create a secure virtual environment. While some of these tools are cross-platform, the vast majority of them are geared specifically to VMware vSphere.
In this post we will look at Server Security, and we will follow-up with another post about Desktop Security? Are these very different? I believe so, desktops have daily, second by second user interactions. For desktops, one of the most important aspects is look and feel such as response time for actions. So things need to be as fast as possible. With Servers however, user interactions are limited and therefore have slightly different performance and security requirements. What may be acceptable for a server may not be acceptable for a desktop. So what do the tools provide for servers?
Virtualizing business critical systems requires that a layer of virtualization management solutions be added to the virtualization platform. Virtualization management solutions in the areas of virtualization security, virtualization configuration management, virtualization service and capacity management, virtualization service and capacity management, virtualization provisioning and lifecycle management and backup and recovery should be added to the platform.
The Wall Street Journal had an interesting article on the United States General Services Administration has approved the acquisition of some cloud services for use by the Federal Government including many of the Google Apps such as Gmail, Google Docs, etc. Since these services are for sale as well as freely available this sounds more like an admission that they can be used. Will other governments follow suit? But should they be used? That is really the question.
There are two sides to any government, the classified and the unclassified. These are general terms that quantify how the government can use services. While all services require quite a bit of security, classified utilization requires even more, in many cases what most would consider to be “uber-security” requirements. The types of requirements that impact usability in some way. Can these tools provide adequate security?

Virtualization Security, Configuration Management, Service and Capacity Management, Provisioning and Lifecycle Management, and Backup/Recovery are essential functions that must be added to a virtualization platform when virtualizing business critical applications. VMware vSphere is clearly the market leading and most robust virtualization platform – and clearly the virtualization platform most suitable as the foundation of a virtualization system designed to support business critical applications. However, the virtualization platform must be complemented with third party solutions in these areas in order to create a system that can truly support business critical applications in an effective manner.
The Virtualization Security Podcast on 7/22 was all about the news of the week with our panelists discussing how this news affects everyone and anyone with respect to Virtualization Security. The news discussed:
* NIST Released their Guide to Security for Full Virtualization Technologies (Draft)
* There is a Security issue with VMware vSphere 4.1
* VMware discussed the new vShield Zones Edge and vShield App products
* HyTrust and Catbird announced a cooperative effort
When you read books on virtualization, cloud computing, security, or software product sheets a common word that shows up is Policy. Tools often claim to implement Policy, while books urge you to read or write your Policy. But what does Policy imply?
Webster (webster.com) defines policy as:
1 a : prudence or wisdom in the management of affairs b : management or procedure based primarily on material interest
2 a : a definite course or method of action selected from among alternatives and in light of given conditions to guide and determine present and future decisions b : a high-level overall plan embracing the general goals and acceptable procedures especially of a governmental body
When you read policy in product literature and books we are looking at definition number 2 and often a over b. But what does this mean to those who administer and run virtual environments or make use of cloud services?
Catbird and HyTrust have teamed up to deliver a product that provides front-end access and compliance control for well understood actions via HyTrust, for all other actions, including intrusions, Catbird Security provides compliance control, firewall, IDS, and IPS. In other words, proactive security via HyTrust and reactive security via Catbird.

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.
