Use Case

Safe export of data from segregated networks

SAFE EXPORT OF DATA FROM SEGREGATED NETWORKS

When exporting data, such as transactions in financial institutions, military data or human DNA sequence data, the most rigorous controls must be in place. In these cases, organisations often handle data storage solutions like USB sticks or CDs, which introduces the risk of human error by misplacement or procedural errors.

To overcome the challenges, the Oakdoor™ Export Diode can be embedded into the network infrastructure at the point of policy enforcement.  The hardware-based diode can only export authorised files when all prerequisites are in place and the correct procedures for data export are followed. The diode implements  the National Cyber Security Centre Safely Exporting Data
design pattern Release Control and Flow Control operations.

Step one is to make sure there’s a proper data authorisation workflow in place, to ensure that only approved data is exported. The workflow is defined based on your security policy and operational procedures and could also demand data encryption to ensure only the intended receiver can read it.

Step two is to digitally sign the file with a special cryptographic key before sending the file to the Export Data Diode.  If the signature is verified as correct, the Oakdoor™ Export Diode will release the file to the destination network.
