US Patent 8365294 Hardware platform authentication and multi-platform validation

Methods and apparatuses enable authentication of a hardware platform on a network. The authenticated hardware platform can validate the credentials of virtual machines executing on the hardware platform. The authentication of the hardware platform on the network enables network access to the validated virtual machines. The network access of the virtual machines is managed by the hardware platform, including allowing differentiated access based on, for example, the security posture of each virtual machine.
