Virtualization, Containers and Other Sandboxing Techniques Should be on Your Radar Screen

by Neil MacDonald  |  March 16, 2013  |  Comments Off

  The idea of “sandboxing” potentially malicious content and applications isn’t new but interest in this type of approach on Windows desktops is growing. Further, the increasing variety of virtualization and abstraction techniques available on Windows create isolation that can be used to provide security separation – aka “sandboxing”. Given the innovation around virtualization techniques […]

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. […]

What we Need is the Equivalent of Apple for Enterprise Data Centers

by Neil MacDonald  |  August 29, 2012  |  Comments Off

I’ve spent the last three days in Silicon Valley – some of it at VMworld and some of it with a client. With the flight out and back to the West Coast, I’ve had some time to do some thinking. Cleary, there’s a perception that hardware is commoditizing and that there’s little or no premium left in […]

Security Observations from European Symposium

by Neil MacDonald  |  November 14, 2011  |  1 Comment

I spent the last week in Barcelona with 4,000+ attendees at the 2011 Gartner European Symposium. It was a new venue for Gartner (we were displaced from Cannes by the G20), and I’m happy to say it was a fantastic with record attendance. Security was front and center of attendee interests. We had a total […]

US Symposium Summary from a Security Perspective

by Neil MacDonald  |  October 24, 2011  |  1 Comment

With 8,000+ attendees (25% of which were CIOs) and at least 1,000 more analysts, vendors and support staff, you can imagine it was quite a scene. In addition to three presentations, I had more than 30 fantastic one on ones with attendees over the four […]

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 […]
