Abstract
In one implementation, an original physical profile file and a configuration baseline are stored for a virtual machine. The physical profile file includes physical characteristics of a physical device running the virtual machine. The configuration baseline includes configuration settings or attributes of the instance of the virtual machine. A network device detects current value for at least one physical characteristic and compares the current value to the original physical profile file. When the current values deviate enough from the original physical profile file to exceed a threshold amount of deviation that is permissible, the network device determines that the virtual machine has been moved to another physical device. In response, the network device monitors current configuration settings or attributes with respect to the configuration baseline in order to detect an unauthorized usage of the virtual machine.
