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 [...]

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 [...]

US Symposium Summary from a Security Perspective

by Neil MacDonald  |  October 24, 2011  |  1 Comment

Last week I attended Gartner’s US Symposium conference in Orlando. 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 [...]

Seven Cloud Computing Pet Peeves

by Neil MacDonald  |  July 15, 2011  |  Comments Off

1) Treating Cloud as one thing. At a minimum, clarify whether you are talking about SaaS, PaaS, or IaaS – and whether you are talking about public or private cloud implementations. 2) Assuming Cloud always means Public Cloud Cloud is a computing style, not a location. 3) Citing Security as the number one issue to [...]

Real-world Systematic Workload Reprovisioning

by Neil MacDonald  |  June 23, 2011  |  Comments Off

I’m here at the Gartner Information Security summit on the fourth and final day. We had a record number of attendees – at least 1700 by my estimate. Attendees have the ability to book one on one conversations with the analysts and my schedule was completely full. One of the conversations with a client was [...]

Don’t Trust Your Servers

by Neil MacDonald  |  June 17, 2011  |  3 Comments

One of the toughest problems in information security is addressing advanced intrusions that have bypassed traditional security controls and now reside undetected on enterprise systems. With financially motivated attacks and state-sponsored “advanced persistent threats” both on the rise, intrusions can remain undetectable for extended periods of time. We have reached a point where our systems [...]

Improving Security by Killing Server and Desktop Workloads

by Neil MacDonald  |  June 16, 2011  |  Comments Off

It sounds counterintuitive, but today’s advanced threat environment requires new approaches to the ongoing security and management of server and desktop workloads. The trouble with Advanced Persistent Threats is that, by definition, they have evaded our traditional network and endpoint security controls and now reside undetected in our IT Systems. How many advanced intrusions will [...]

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 [...]

Symantec’s CEO, Enrique Salem, kicked off the morning with a discussion of Symantec’s role in the changing world of IT and information security. Enrique called out five megatrends that are challenging our preconceptions about the role of IT and information security: [...]
