What do vendors say about Virtualization and security?

VMShield. Another vendor in the VM security space is Catbird, which launched VMShield in February to secure VMs from human management errors and threats from the network.

"Some hacker in Uzbekistan is not the big problem in the virtual world; the problem is management change," said Tamar Newberger, Catbird's VP of marketing. "With VMware, one person has all access to the virtual environment, instead of the four people it takes to configure a physical server. Human error is the biggest risk."

Catbird software can halt communications that do not comply with security policies, preventing security threats due to human error. The product includes change control and secondary control validation; automatic quarantine of unauthorized VMs; server sprawl management; and network data protection against vulnerabilities, known attack signatures and VM-to-VM attacks.

VMware and XenServer are monitored, and when customers request Hyper-V security, CatBird will provide it, Newberger said.

The software costs $US3,250 per ESX host plus a 20% subscription fee per year, or users can opt to pay $US18 per month, per VM, Newberger said.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

OS Virtualization comparison: Parallels' Virtuozzo vs the rest

Virtuozzo's main differentiators versus hypervisors center on overhead, virtualization flexibility, administration and cost. Virtuozzo requires significantly less overhead than hypervisor solutions, generally in the range of 1% to 5% compared with 7% to 25% for most hypervisors, leaving more of the system available to run user workloads. Customers can also virtualize a wider range of applications using Virtuozzo, including transactional databases, which often suffer from performance problems when used with hypervisors. On the administration side, customers need to manage, maintain and secure just a single OS instance, while the hypervisor model requires customers to manage many OS instances. Of course, the hypervisor vendors have worked hard to automate much of this process, but it still requires more effort to manage and maintain multiple operating systems than a single instance. Finally, OS virtualization with Virtuozzo has a lower list price than the leading hypervisor for comme...
