Particular embodiments described herein provide for a system that can be configured to determine an identification (ID) of a computer processing unit (CPU) using one or more tests and/or measurements, intercept the result of a query from a process to determine the ID of the CPU, replace the result of the query if the result of the query does not match the determined ID of the CPU, and communicate the result of the query that includes the determined ID of the CPU to the process. In an example, the query is a CPUID opcode and the results of the query are intercepted after passing through a hypervisor.
