Software Defined Data Centers and Security–What’s in a Name?

by Neil MacDonald  |  January 29, 2013  |  2 Comments

Last fall, I wrote a research note for Gartner clients titled “The Impact of Software-Defined Data Centers on Information Security” that explored the impact of software defined infrastructure on security – and the evolution of information security infrastructure to become software-defined itself. Today, I saw that NetCitadel had announced an offering in this emerging space [...]

Virtual Firewalls or Physical? Wrong Question.

by Neil MacDonald  |  November 5, 2012  |  2 Comments

I still see people getting bogged down in rather meaningless arguments as to whether or not firewalls will be virtualized. They will (and, in fact, are). The bigger trend is the shift from proprietary hardware to software running on commodity hardware (in almost all cases, x86). That’s the big shift. Whether or not a given [...]

Five Myths and Realities of Virtualization Security

by Neil MacDonald  |  September 6, 2012  |  3 Comments

I’ve been researching the intersection of virtualization and security since 2007 and find myself continually running into these myths pertaining to virtualization and security: 1) Myth: Physical is better than virtual. Reality: Define “better”. Software and virtual appliance-based security controls are more adaptable to the rapidly changing infrastructure requirements of a modern, virtualized data center. [...]

I’ve been absent from my typical blogging routine getting my material finalized for two Gartner upcoming US-based summits in June 2012. The first is Gartner’s Infrastructure and Operations Management Summit being held in Orlando the week of June 4th. This conference is focused on infrastructure and operations solutions for managing desktops, servers, and mobile devices [...]

Building Context-Aware Security: VMware Acquires PacketMotion

by Neil MacDonald  |  August 27, 2011  |  Comments Off

VMware quietly disclosed it has acquired PacketMotion in this recent blog post by Dean Coza of VMware. We identified PacketMotion as a cool vendor in Gartner in this 2009 research for clients. Essentially, PacketMotion uses standard Intel-based hardware appliances  (as well as a virtualized probe implementation that runs inside of virtualized environments) to deliver full [...]

Is Single Instance Security the Future?

by Neil MacDonald  |  June 6, 2011  |  Comments Off

I’ve been researching the intersection between virtualization and security for several years. Like security and cloud computing, virtualization and security is also following a maturity curve. The first several years were discussions with clients on how to deploy virtualization securely. Over the past 2 years, I’ve had an increasing number of calls on the virtualization [...]

NIST Publishes Its Virtualization Security Guidelines

by Neil MacDonald  |  February 10, 2011  |  Comments Off

Last week, the US National Institute of Standards and Technology (NIST) published its final virtualization security guidelines. There are already guidelines available from the Center for Internet Security, VMware, Microsoft, and Citrix as well as guidelines from the Defense Information Security Agency in the form of STIGs. NIST adds to this collective knowledge and expands [...]

Yes, Hypervisors Are Vulnerable.

by Neil MacDonald  |  January 26, 2011  |  5 Comments

In one of my first posts as a blogger nearly 2 years ago, I discussed the potential for disaster if a compromise in the virtualization platform (hypervisor/VMM) occurred. Last year (I was intending to comment on this at the time, but it slipped my mind), I was reading the IBM X-Force 2010 Mid-Year Trend and [...]

Securing Private Clouds Requires Changes to Information Security Infrastructure

by Neil MacDonald  |  December 1, 2010  |  4 Comments

As organizations virtualize their data centers, information security has had to evolve to support this. The same will be true as data centers evolve to private clouds – security must evolve to support the needs of private cloud infrastructure. For most organizations, virtualization will provide the foundation and the stepping stone for the evolution to [...]

Lessons from the Windows Firewall on the Evolution of Virtualization Security

by Neil MacDonald  |  November 8, 2010  |  2 Comments

In this research note on deploying Windows 7 security features for clients, I explore in detail the security capabilities baked into Windows 7 – AppLocker, BitLocker, BitLocker To Go, the Windows Firewall, USB Port Control and so on. One question I get from clients is whether or not to use the built-in capabilities of Windows [...]
