Any accessory that provides wired networking capabilities to a Samsung Android device must not be connected to a DoD network (for example: DeX Station [LAN port], USB to Ethernet adapter, etc.).
If a Samsung Android device uses an accessory that provides wired networking capabilities, and that accessory is connected to a DoD network, then the Samsung Android device would also be connected to the DoD network. Samsung Android devices most likely have a number of personal apps installed that may include malware or have high-risk behaviors (for example, offloading data from the phone to third-party servers outside the United States). In addition, smartphones do not generally meet security requirements for computer devices to connect directly to DoD networks.
Note: Samsung DeX mode (with input devices) will not work unless the "USB host mode exception list" is configured (see requirement KNOX-09-000755 for more information).
