Defense in Depth: Authentication and Authorization

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?

Security of Performance and Management tools within the Virtual Environment

One of the basic tenants of virtualization security is to protect the management components of your virtualization hosts by placing these all important components on a separate network. These components often include management servers such as SCOM, vCenter, XenCenter, VirtManager, etc. as well as the management appliances of your virtualization hosts. In essence, the use of a properly configured, firewalled, and monitored virtualization management network would be the simplest and most effective security measure that can be made to day within any virtual environment. A message shared by Citrix, VMware, myself, and many others.

The problem is that not everything is as black and white as security folks desire. If we implement performance and other management tools, we often need to expose part of our all important virtualization management network to others. But how do we do this safely, securely, with minimal impact to usability? Why do we need to this is also another question. You just have to take one look at the Virtualization ASsessment TOolkit (Vasto) to realize the importance of this security requirement. But the question still exists, how do you implement other necessary tools within your virtual environment without impacting usability? Which we discussed on the May 5th Virtualization Security Podcast.
