The Virtualization Practice

ITasaService

There has been quite a bit written about Code Spaces and how unauthorized access to its ITaaS console granted enough permissions to delete everything out of Amazon, including backups. There are lessons here not only for tenants, but also for those vendors who create ITaaS consoles, such as VMware (vCHS, vCD, vCAC, vCenter, Orchestrator, etc.),…

CloudComputing

Recently I have had the pleasure of discussing security with a number of cloud providers. Specifically, we talked about what security they implement and how they inform their tenants of security-related issues. In other words, do they provide transparency? I have come to an early conclusion that there are two types of clouds out there:…

The Hybrid Cloud has 100s if not 1000s of APIs in use at any time. API security therefore becomes a crucial part of any hybrid cloud environment. There are only so many ways to secure an API, we can limit its access, check the commands, encrypt the data transfer, employ API level role based access controls, ensure we use strong authentication, etc. However, it mostly boils down to depending on the API itself to be secure because while we can do many things on the front end, there is a chance that once the commands and actions reach the other end (cloud or datacenter) that the security could be suspect. So how do we implement API security within the hybrid cloud today?

VirtualizationSecurity

By far, the lowest hanging fruit of virtualization and cloud environment security is the segregation of your management control from your workloads. Separation of data and control planes have been recommended for everything from storage (EMC ViPR) up to the workloads running within virtual machines. The same holds true for cloud and virtual environment management tools, tasks, and functions. Up to now there have been very few choices in how such segregation could occur using properly placed firewalls or by using some form of proxy and the only proxy available was HyTrust. But this has changed. There are some other tools that will help with this segregation of data from control and do they give the level of auditing we require to solve the delegate user problem?

RSA Conference: What was Interesting

As I met with people at RSA Conference last week, the common question was: What was interesting and new? My view was from the world of virtualization and cloud security, which often differs from general or mobile security. This show was more about general and mobile security than it was about virtualization and cloud security due to the confluence of VMware Partner Exchange (PEX) and RSA Conference. There were quite a few things that were new from the show floor, RSA Innovation Sandbox, and other conversations.

VirtualizationSecurity

On the 7/29 Virtualization Security podcast we continued our discussions on defense in depth. We discussed authentication and authorization with IdentityLogix. IdentityLogix provides a unique solution that correlates users and groups against VMware vSphere’s own role based access control stores. In other words, IdentityLogix can identify if a user or group within active directory has more access to VMware vSphere’s management tools than they were intended to be allowed based not only on the user’s username but on the groups in which the user belongs. Why is this important to know?

VMworld2012150x27

Now that VMworld 2012 is well underway I wanted to share some of my first thoughts and observations about the conference. At the start of the conference, during the first General Session, the virtual passing of the torch from the outgoing CEO, Paul Maritz to the new incoming CEO, Pat Gelsinger took place with Mr. Gelsinger getting his opportunity to say hello to a crowd of around twenty thousand people that are present at the show.
