One development that occurred this year is the release of VMware’s security APIs. After talking up the idea since February 2008, VMware in April 2009 finally released its VMsafe APIs intended to help security vendors build products to work with its platform.
“We’re not using the VMware APIs today due to performance,” says Richard Park, senior product manager at Sourcefire, which in early December shipped its first virtualized sensor and management console for VMware ESX and vSphere4. Sourcefire’s traditional physical appliances are network sensors that can do both intrusion-detection monitoring and intrusion-prevention blocking. But at this point, the Virtual 3D Sensor and Virtual Defense Center will only provide monitoring visibility into VMware’s ESX hosts, not blocking of attacks.
At the Gartner ITExpo in October, Gartner Vice President Neil MacDonald publicly excoriated some security vendors for not moving more rapidly to come up with software-based virtual appliances, insinuating they would rather stick to their old ways of selling expensive hardware boxes. Enterprise customers are rapidly virtualizing their IT environments and often unwittingly creating less-secure results even as they reap the many benefits of virtualization, MacDonald says. Roping off virtualized servers with virtual LANs alone — a common practice — “is not sufficient for security separation,” MacDonald says. MacDonald says virtualization is causing some “business-model disruption” in security and praised the efforts of some vendors, including Trend Micro, to leap in with new offerings to take on the virtualization challenge.
Trend Micro’s Core Protection for Virtual Machines, antimalware software that was designed for use with VMware, was released in the third quarter. According to Bill McGee, senior director of product marketing at Trend Micro, both products make some use of tools in VMsafe. VMware has been among the most aggressive of the virtualization software vendors to open up their technology to optimize security functions, he says, while so far the actions of Citrix and Microsoft seem “more limited” in this area.
For its part, VMware says it’s glad to see a number of vendors, including Altor Networks, Reflex, ISS IBM and Trend Micro, adopting the VMsafe technology.
According to Forrester Research, adding hypervisor technology (Citrix Xen, VMware vSphere and Microsoft Hyper-V) “does add some marginal risk to IT environments, because it layers additional software on top of existing operating systems.
According to Jacquith, one disappointment remains VMware’s Live Migration feature for configuring VMs so that they automatically migrate from one farm host to another, for purposes of fault tolerance and business continuity.
