Description
Allowing movement of files between the container and personal side will result in both personal data and sensitive DoD data being placed in the same space. This can potentially result in DoD data being transmitted to non-authorized recipients via personal email accounts or social applications, or transmission of malicious files to DoD accounts. Disabling this feature mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #45
