Abstract
A system for data protection includes a computing device comprising a processor, a Hardware Root of Trust (HRoT) module and a storage device. The HRoT device is configured to: validate integrity of the computing device; authenticate the computing device to communicate with the storage device; and take over control of storage device access and behaviour whenever suspicious or unauthorized data access from local or remote computing devices is detected. The HRoT device is further configured to, in response to detecting a security risk to at least one of the computing device and the storage device, block communication of the storage device.
