Software Defined Security: Is it Achievable?

VirtualizationSecurityCloud based security is about securing the data, yet compliance requirements are often about securing the environment, such as PCI’s requirement for web application firewalls, which protect web servers and perhaps applications and imply protection of data.  But they do not directly protect data. How can a Software Defined Data Center implement a form of Software Defined Security automatically to meet not only compliance requirements, but security around a particular mote of data? Continue reading Software Defined Security: Is it Achievable?

Is the Software Defined Data Center the Future?

ITasaServiceVMware purchased Nicira, backed the Openflow Community, and is now touting software defined data centers (SDDC).  But what is a software defined datacenter? Is it just virtualization or cloud with a software defined network? Or is it something more than that? Given heavy automation and scripting of most clouds, do we not already have SDDC? If not where are we going with this concept? What does SDN add to the mix? Continue reading Is the Software Defined Data Center the Future?

Type 0 Hypervisor – Fact or Fiction

DataCenterVirtualizationWhile looking around the web for anything new with virtualization, I kept seeing more and more posts and articles about the new type of virtual hypervisor. Type 0, now this sounds interesting and I found these definitions for each type of hypervisor. Continue reading Type 0 Hypervisor – Fact or Fiction

Storage Hypervisors: Worth the Hype

StorageNetworkingJust what are storage hypervisors? There are several companies that claim to have storage hypervisors. Wikipedia states that  a hypervisor is “conceptually one level higher than a supervisory program”. We also know that from our normal use of hypervisors that they manage the underlying resources that a guest uses. Do these definitions work for a storage hypervisor? Continue reading Storage Hypervisors: Worth the Hype

Defense in Depth: Know Your Attack Surfaces

VirtualizationSecurityThe 6/28 Virtualization Security Podcast we spoke about attacks, defense in depth, and compliance with Davi Ottenhiemer and Matt Wallace. Davi and Matt just published a book (available on the Virtualization Bookshelf under Security) on how to defend your virtual environment against attack. Unlike other books, this approaches the problem from the point of view of well know attacks. It even gives examples of some of the more interesting attacks against any of the virtual environments, not just VMware vSphere. The discussion eventually found its way to even newer attacks and their impact on the environment. Continue reading Defense in Depth: Know Your Attack Surfaces

Defense in Depth: Storage Security in a Hybrid Cloud

StorageNetworkingStorage Security is not only about Encryption, which is just one aspect of Storage Security requirements for the virtual and cloud environments. It is also about increasing defense in depth and knowledge of what is touching your storage environment. As well as providing security around those touch points and to a great extent auditing and protecting the data residing within the storage devices regardless of where the devices live: within the virtual environment or within a cloud. Traditionally we have the following storage security capabilities:
