"There's an operating system and application in every package, every one with its own configuration and patch status and you have no idea what's in there or who's going to maintain it or what the long-term risk is going to be," MacDonald says. If the hacker owns the hypervisor, he/she owns all data traversing the hypervisor and is in a position to sample, redirect, or spoof anything. Hypervisors help in secure isolation of multiple virtual machines running on single physical hardware. The overarching issue with virtual servers is responsibility, MacDonald says.

The National Security Agency has taken that concern not only to heart, but to software development labs, coming up with a virtual-server management scheme called NetTop that requires a configuration preventing VMs running on the same machine from interfering with one another. Virtualized environments remove that restriction and create a one-to-many attack scenario: attack the host, own the guests-or even attack one guest, possibly own them all. Multi-tenancy is a needed requirement to be provided in. By If, or when, attacks focused on virtual machines become readily available, the attacker potentially only has to spend time attacking one virtual machine, which could lead to compromising other virtual machines over a closed network, and eventually escaping the virtual VMM environment and accessing the host. The decoupling of physical and logical states gives virtualization inherent security benefits.
