While not particularly new news, the next version of the Cisco Nexus 1000v will be free, unless you want the security features. This is an interesting shift from Cisco with respect to VMware vCloud Director, the Nicira purchase, furthering UCS, and Cisco within non-UCS data centers. However, given other announcements, with respect to OpenStack, perhaps this is more a play to level the playing field between cloud architectures? But what I find most interesting, is that the changes to the Nexus 1000v also align with the changes we see in the vCloud Suites from VMware.
There are several improvements in virtual networking and security within the latest vSphere and vCloud products. vCloud Networking and Security lowers of the overall cost to implement endpoint security within a vSphere environment. VMware has accomplished this by including vShield Endpoint into vSphere. There by lowering the cost to offloaded antivirus and malware to just the product chosen to implement antivirus and antimalware.
VDI Security offers little security over well managed standard desktops and can expose more security risks: what is the impact of this?
Acquiring DynamicOps has kick-started VMware into a heterogeneous virtualization management strategy. This will be demonstrated in detail at VMworld this Fall. We now face a dramatically different virtualization landscape. The focus has now shifted to management – of business critical applications running on multiple virtualization platforms and potentially distributed across internal data centers and public clouds.
Virtualization and Cloud Security architects, pundits, and writers like myself often talk about protecting the data within the virtual and cloud environments. However, in order to protect that data we need to be able to determine how the data will be used, accessed, modified, and eventually removed. So, how can we understand data security without understanding the application around it. But there is an even more fundamental problem, how do we define the application and the security measures we should take?
The 2/9 Virtualization Security Podcast was a discussion on when would one use a virtual firewall. This was in response to being told that there are some people that would never use a virtual firewall for anything, and that got me thinking. Outside of the politics involved with using virtual vs physical firewalls, when would you use one? What are the cut offs, and best practices around using virtual firewalls. We were joined by Rob Randell of VMware to discuss this point.
