Abstract
A method and system for securing a read write storage (RWS) device, the method comprising, providing the RWS device, the RWS device comprising a controller comprising a processor and a bit bucket storing data, and employing the controller to corrupt at least a portion of the data.
Claims31
A method for securing a read write storage (RWS) device, the method comprising:
- determining that there is evidence of an attack on the RWS device;
- employing a sanction, wherein the employing is performed by a controller on the RWS device and the employing comprises at least corrupting a portion of data on the RWS device, wherein the corruption of the corrupted portion of data is reversible by an authorized server;
- forwarding logging information regarding the corrupted portion of data to the authorized server for analysis;
- subsequent to a determination by the authorized server in accordance with at least the results of the analysis that the RWS device may resume functioning normally, receiving a private key needed to reverse the corruption from the authorized server;
- and
- using the received private key to reverse the corruption of the corrupted portion of data.
3 more elements
A secure RWS device comprising:
- a sanction logging module configured to log information regarding corrupted data on the RWS device;
- and
- a controller configured to:
- determine if there is evidence of an attack on the RWS device,
- if there is evidence of an attack on the RWS device, employ a sanction, wherein the sanction is at least corrupting a portion of data on the RWS device, wherein the corruption of the corrupted portion of data is reversible by an authorized server,
- forward logging information regarding the corrupted portion of data to the authorized server for analysis,
- subsequent to a determination by the authorized server in accordance with at least the results of the analysis that the RWS device may resume functioning normally, receive a private key needed to reverse the corruption from the authorized server, and
- reverse the corruption of the corrupted portion of data with the private key.
5 more elements
A secure RWS device comprising:
- a sanction logging module configured to log information regarding corrupted data on the RWS device;
- and
- a controller chip attached to a PCB in a Ball-Grid-Array configuration, wherein lines connecting the controller chip components on the PCB are obscured in a lower layer of the PCB, and the controller is configured to:
- determine if there is evidence of an attack on the RWS device,
- if there is evidence of an attack on the RWS device, employ a sanction, wherein the sanction is at least corrupting a portion of data on the RWS device, wherein the corruption of the corrupted portion of data is reversible by an authorized server,
- forward logging information regarding the corrupted portion of data to the authorized server for analysis,
- subsequent to a determination by the authorized server in accordance with at least the results of the analysis that the RWS device may resume functioning normally, receive a private key needed to reverse the corruption from the authorized server, and
- reverse the corruption of the corrupted portion of data with the private key.
