Abstract
An apparatus including non-volatile memory to store a forensic key and data, the data received from a host computing system. A processing device is coupled to the non-volatile memory and is to: allow writing the data, by the host computing system, to a region of the non-volatile memory; in response to a lock signal received from the host computing system, assert a lock on the region of the non-volatile memory, the lock to cause a restriction on access to the region of the non-volatile memory by an external device; and provide unrestricted access, by the external device, to the region of the non-volatile memory in response to verification of the forensic key received from the external device.
