There is some debate amongst backup vendors on what defines an agent, some consider any amount of scripting to be an agent, while others imply it is what does the data transfer plus any amount of scripting necessary. Is there a need for both Agent and Agent-less within a virtual environment? This also begs the question, who is responsible for properly handling the application whose data you are backing up? Continue reading Agent and Agent-less Backup in the Virtual Environment
More and more is coming out about the attack from a MacDonald’s that left an organization crippled for a bit of time. The final tally was that the recently fired employee was able to delete 15 VMs before either being caught or he gave up. On twitter, it was commented that the administrator must not have been a powershell programmer because in the time it takes to delete 15 VMs by hand, a powershell script could have removed 100s. Or perhaps the ‘Bad Actor’ was trying to not be discovered. In either case, this has prompted discussions across the twitter-sphere, blog-sphere, and within organizations about how to secure from such attacks.

At the NE VMUG, while walking the floor I saw a new virtualization backup player, perhaps the first generic Replication Receiver Cloud: TwinStrata. And information gained while not at the NE VMUG. There is also a new virtualization backup player just for Hyper-V: Altaro. As well as a new release of Quest vRangerPro. The Virtualization Backup market is a very dynamic market with new ideas, technologies, and concepts being put into the market at every turn. In many ways, the market leaders are not the bigger companies but the smaller and fast growing companies. In the past, it was about features associated with pure backup, but now it is about features and fast disaster recovery and recovery testing.

Security in the cloud and the virtual environment is ‘all about the data’ and not specifically about any other subsystem. It is about the data. As such the data has something it knows (the contents of the data), something it is (its signature), and something it has (its digital rights) and since it has these three elements, the data has all it has identity. However, protecting the data requires us to put things between the data and the real world such as firewalls, and complex role based access controls, as well as methods to replicate the data to other locations in a non-intrusive mechanism. The goal to such replication could be to ensure multiple sites have the same data (such as a hot-site) or to have the data available in another locations in case of disaster. In addition, such data must maintain its identity. Continue reading Replication Receiver Clouds: Protecting your Data
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
Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.
