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. Continue reading Security of Performance and Management tools within the Virtual Environment

vCenter Operations: Integrated and Secure?

VMware released 3 versions of vCenter Operations, standard, advanced, Enterprise.  We have already discussed the abilities of vCenter Operations vCenter Operations – vSphere Performance, Capacity and Configuration Management with Self Learning Analytics but is this an integrated and secure implementation of monitoring or do we need more security than what is provided?

At the time the first article was written there was a bit of vital information we did not have available to us. That is how to access vCenter Operations Standard or Advanced in a multi-tenant manner, that has now been provided. vCenter Operations Alive functionality can be accessed directly from a web browser using your VMware vCenter Credentials, which allows you to see the Alive status of any VM you have the permissions to view. This capability is a huge capability, as it now allows me to provide a non-vSphere Client mechanism to view the status of the virtual environment.
