The macOS system must disable Bluetooth Sharing
Description
Bluetooth Sharing must be disabled.Bluetooth Sharing allows users to wirelessly transmit files between the macOS and Bluetooth-enabled devices, including personally owned cellphones and tablets. A malicious user might introduce viruses or malware onto the system or extract sensitive files via Bluetooth Sharing. When Bluetooth Sharing is disabled, this risk is mitigated.[NOTE]====The check and fix are for the currently logged in user. To get the currently logged in user, run the following.[source,bash]----CURRENT_USER=$( /usr/sbin/scutil <<< "show State:/Users/ConsoleUser" | /usr/bin/awk '/Name :/ && ! /loginwindow/ { print $3 }' )----====Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000095-GPOS-00049
