EMC VNXe Spurs Thinking Outside the Box

Chad Sakac mentions on his blog that VNXe “uses a completely homegrown EMC innovation (C4LX and CSX) to virtualize, encapsulate whole kernels and other multiple high performance storage services into a tight, integrated package.” Well this has gotten me to thinking about other uses of VNXe. If EMC could manage to “refactor” or encapsulate a few more technologies, I think we have the makings of a killer virtualization security appliance. Why would a storage appliance spur on thinking about virtualization security?

Cisco Pushing More vNetwork into Hardware

In the first Virtualization Security Podcast of 2011, we had Brad Hedlund with us once again. Not to talk about the Cisco Virtualization Security Gateway (VSG), but about the security of what I call physical-virtual devices that provide network virtualization within the hardware. Or what Brad Called Network ID Virtualization (NIV). Cisco has taken its VN-Link technology to extend the networking of a VM directly into the core switch when using vSphere.

Digging out after a Snowstorm: Similar to our virtual environments?

Sooner or later that perfect landscape of white is marred by new mounds of snow and clear-cut paths through it to the various locations on the property. When you look at these paths and the snow is high enough, they look like tunnels. The large tunnels (driveway) meet smaller and smaller ones. The perfect landscape of snow is now marred. This is just how a firewall looks when you put holes in it to let through various services. The more services, the more tunnels and paths will be cut. When speaking about the cloud or virtual environments, the increase in paths and entry points becomes a serious issue.

Threat Analysis: Layers upon layers

When we think of the threat to a virtual environment or the cloud, what do we think about? First it is important to understand how the cloud is layered ontop of the virtual environment. Given a cloud stack, where are the entry points for SaaS, PaaS, IaaS, and Cloud management? At the recent Minneapolis VMUG I attempted to relay that information to the attendees. Once we understood the layers we could then concentrate on the threat vectors to the cloud and virtual environment.

Entry into the Cloud…

In the last Virtualization Security Podcast on 12/16 we had with us James Urquhart who manages cloud computing infrastructure strategy for the Server Provider Systems Unit of Cisco Systems. Author of the popular C|NET Network blog, The Wisdom of Clouds. James shared with us some of his Wisdom over the hour. The discussion covered what is preventing people from Entry into the Cloud and why private and hybrid clouds are going to stick around for quite a while and are not a passing fad. We answered the question of why people are reluctant to enter the cloud.
