Security threats in a virtual environment

Security is typically a hot-topic due also to several regulations and compliant rules and laws. But more important, a security breach can have huge collateral effects, also if no data has been stoled, or compromised. But, for example, a “simple” DoS attack that makes a service not available can have a bad effect on the reputation of a B2C company. This post will try to give an idea of some possible security threads in a virtual environment based on VMware vSphere (but several concepts are quite general also for other virtualization platforms) and some possible approaches to minimize the effect or prevent the attacks.

Specialize Windows Server Hyper-V guest OS automatically

Last year I have written a topic on Starwind to create VMs from PowerShell. That enables to automate the creation process without using a GUI, either from Virtual Machine Manager or Hyper-V Manager. But a VM deployment is not finished when the VM is created but when the application is deployed. Before deploying the application, the OS must also be installed and specialized. This topic shows you the method I use to deploy and specialize a VM without a single click.

Encryption of VMware vSphere 6.5 virtual machines and vMotion migrations. And their performance

As many admins of virtual infrastructures know, for the first time ever, VMware vSphere 6.5 received the long awaited encryption feature of both virtual disks content and vMotion hot migrations. The VMs encryption works based on AES-NI algorithm, and the key management is carried out based on KMIP 1.1 standard. When I/O operation comes to the disk of the virtual machine, it is immediately encrypted on-the-fly, which provides complete security against data security attack.
