In my last article, EUC Use Cases: Secure Hybrid Cloud, we looked at how the user could be getting to our data. By doing this, we can place security at the union of data and the user, wherever the data resides and however the user gets there. Yet, we cannot forget where the data is presented. In order to present data, data is copied from its repository to some other device. Now, in the case of virtual desktops, that data is copied as graphical constructs derived from the data; for file servers, the data presented is a raw form of the data. So, to secure everything from end to end, what do we really need? Continue reading EUC Use Cases: What Do We Need?
Whenever I talk to security vendors and others about where security is going, or more to the point, should go, I draw out a use case I have developed over the years. It has grown and changed as the concept of the secure hybrid cloud has developed and expanded. The example I use demonstrates the need for policy not only to cover the data and systems, but also to follow the user as they access the data. The entry point to any secure hybrid cloud is the user. Where that user goes tells us how they touch and access data. We may want a security context around the data, but how that context should react depends on how, from where, with what, when, and hopefully why the data is accessed.

At VMworld 2014, VMware announced its easy-to-install OpenStack distribution, VMware Integrated OpenStack. This got me thinking, as normally OpenStack refers not just to the OpenStack distribution but to a specific underlying hypervisor as well, usually KVM. However, we know that OpenStack works equally well on KVM, vSphere, Hyper-V, and Xen, as it is more of a cloud management layer than a hypervisor. We should probably never lose sight of that little aspect of OpenStack: it is not a hypervisor. As an open-source management stack, it is possible for it to manage cross-hypervisor with a few modifications to its components.
If you’re reading this article, there’s a good chance that you own a smartphone and maybe a tablet or two and that you use ActiveSync to retrieve your corporate email through your personal devices. But did you know that both you and your Exchange administrator have the ability to remote wipe not only your email but your entire device? Continue reading Why Virtualized Email Is Safer than ActiveSync Email on Your Personal Devices
I have written many times about the need for application-centric data protection and data-centric security. But what these both require is that our data protection, security, management, and networking are data-aware. We use applications, but we thrive on data. The more data we have, the more chance we can make use of it, which has resulted in big data tools and big data extensions, even to hypervisors. We talk constantly about moving data closer to processing, with flash and other techniques at the storage layer. But we have not grown other aspects of our systems to be data-aware. It is time this changed. Continue reading Data-Aware Services: Oh, the Places We Could Go!
Every time we as an industry come up with a wonderful innovation, we tend to deploy that innovation before we have the ability to manage it in production. This occurred with the first round of data center virtualization—and resulted in an entirely new category of operations management solutions. But these new solutions did not arrive until several years after CPU and memory virtualization had become widely adopted. Gigamon and VMware seem determined to break this cycle with their joint announcement addressing the question of NSX visibility.
