Description
The Nearby devices feature allows the user to share files with other devices that are connected on the same WiFi access point using the DLNA technology. Even though the user must allow requests from other devices, this feature can potentially result in unauthorized access to and compromise of sensitive DoD files. Disabling this feature will mitigate this risk. SFR ID: FMT_SMF_EXT.1.1 #47
