Abstract
According to one embodiment, an apparatus may store a virtual machine token associated with a virtual machine running on a particular device and a secure image of the virtual machine. The virtual machine token may include a timestamp indicating when the virtual machine was established. The apparatus may receive a token indicating that the particular device is attempting to access a resource. In response, checking the validity of the virtual machine running on the particular device based at least in part upon the timestamp associated with the virtual machine token and a time threshold associated with the virtual machine. If the virtual machine is invalid, then the apparatus may communicate at least one token to initiate the recycling of the virtual machine by replacing the invalid virtual machine with the stored secure image of the virtual machine.
