Further policy details:

This requirement applies to flash media.

Higher risk categories are defined as:
1. Data transfers to or from non-DoD systems
2. Special cases when data must traverse different classification domains

Higher risk data transfer procedures for USB thumb drives:
1. Insert/Unlock USB thumb drive.
2. Load file from the source network.
3. Scan flash media device with an organization approved security scanning software.
4. Set USB thumb drive to read only mode, if possible.
5. Scan file using scanning software on the destination network.
6. Load file to destination network.
7. Use an organization approved disk wipe software to wipe device when data is no longer needed.

Higher risk data transfer procedures for memory cards:
1. Insert card into card reader.
2. Scan disk drive created by memory card using organization approved security scanning software.
3. Scan disk drive created by the memory card using scanning software on the destination network.
4. Load file to destination network.
5. Use organization approved disk wipe software to wipe the device when data is no longer needed.

Check procedures:

1. Interview the site representative.
2. Ask if higher risk data transfers, as outlined above, are performed. If so, ask how this transfer is done and verify compliance with above procedure. If an organization approved security scanning software and disk wipe software are not being utilized when flash media is used for higher risk data transfers, this is a finding.
