It may be possible to transfer work profile data on a DOD Android device to an unauthorized Chromebook if the user has the same Google Account set up on the Chromebook and in the work profile on the Android device. This may result in the exposure of sensitive DOD data. SFR ID: FMT_MOF_EXT.1.2 #47

Review the EMM configuration to confirm phone hub has been disabled.

On the management tool:

1. Open "Nearby notification streaming policy".
2. Verify that "Nearby notification streaming policy" is set to "Disabled".
3. Open "Nearby app streaming policy".
4. Verify that "Nearby app streaming policy" is set to "Disabled".

If on the management tool the "Nearby Streaming Policy" is not set to "Disabled" and "Nearby app streaming policy" is not set to "Disabled", this is a finding.

Note: From a Chromebook, if a device is connected to the Phone Hub, try to set up the Notifications. It will fail to connect to the device to complete the setup if Phone Hub has been disabled on the DOD Android device.

Fix Text

Configure the Google Android 16 device to disable the nearby notification streaming policy to disable Phone Hub.

3. Open "Nearby app streaming policy".
