A trust control management method for security, operable on a computer system generates a unique Trust ID value by combining user-defined values with hardware-specific values associated with the user's computer system and storing the Trust ID value in a memory register physically associated with the hardware of the computer system. A Trust Control Suite (TCS) operable with a server OS/hypervisor maintains a database of user-defined values and hardware-specific values for computer systems clustered in a trusted computing pool. An attestation procedure is performed by the trust control server combining the user-defined values with the hardware-specific values from its database and comparing it to the user-stored Trust ID value stored in the memory register associated with a user's computer system. Depending on whether it is a match or mismatch, the TCS can determine if it is a trusted computer or not, and can take appropriate alerts and policy actions.
