Once you have updated the
Windows Server® 2008 operating system with the Hyper-V™ technology release bits
and enabled the Hyper-V role, you are ready to run virtual machines (VMs) on
your server, now called a virtualization server (also called a “host”).
How does this change your
security? Not much. Hyper-V is designed to be fairly transparent. You secure
your VMs the same way that you secure physical machines. For example, if you
run antivirus software on the physical machine, run it on the VM (not the
host). If you segment the physical server to a particular network, do the same
to the VM.
Securing the virtualization
server itself involves all the measures you take to safeguard any Windows
Server 2008 server role, plus a few extra to help secure the VMs, configuration
files, and data. For more information on helping to secure Windows Server 2008
workloads, see the “Windows
Server 2008 Security Guide.”
