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 [...]

Yes, Cloud Offerings Can Have an On-Premises Element

by Neil MacDonald  |  May 25, 2012  |  4 Comments

One of the common misconceptions that I run into is that a public cloud services provider can’t have an on-premises element to their offering and that having this footprint somehow “breaks” the cloud model. The root of this misconception lies in equating cloud to a location. Cloud is a computing style, not a location. There [...]

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 [...]

Cloud Computing can be More Secure

by Neil MacDonald  |  March 31, 2012  |  7 Comments

In multiple Gartner surveys, security is cited as the number one inhibitor to the adoption of Cloud-based computing. Many IT professionals have a preconceived notion that cloud computing will be less secure than what they can deliver themselves on premises. This is a mistake. An absolute statement that cloud computing will be less secure is [...]

Intrusion Prevention Systems? We Need Intrusion Resilient Systems

by Neil MacDonald  |  February 3, 2012  |  1 Comment

I’ve blogged before about advanced threats that easily bypass our traditional protection mechanisms and reside undetected for extended periods of time on our systems. On one of the panels I moderated on APTs, Dave Merkel from Mandiant put it best. “You are compromised, get over it”. Others in the US Government have come to the [...]

The Market for Dynamic Application Security Testing is Anything but Static

by Neil MacDonald  |  January 4, 2012  |  1 Comment

We’ve just published a new Magic Quadrant for Dynamic Application Security Testing (DAST) for Gartner clients. In Gartner research, we use the term DAST to refer to testing solutions and techniques that are designed to test an application from the “outside in” to detect conditions indicative of a security vulnerability in an application in its [...]

Security Observations from Gartner’s Data Center Summit

by Neil MacDonald  |  December 9, 2011  |  1 Comment

I’m just back from Gartner’s US 2011 Data Center Summit held this week in Las Vegas. In my previous post, I talked about information security vendor’s concerns on the potential impact of the Eurozone crisis on information security spending. Here, I want to outline the top security-related  issues and concerns that I discussed with attendees [...]
