Details
By showing the Bluetooth status in the menu bar, a small Bluetooth icon is placed in the menu bar. This icon quickly shows the status of Bluetooth, and can allow the user to quickly turn Bluetooth on or off.
Rationale:
Enabling ‘Show Bluetooth status in menu bar’ is a security awareness method that helps understand the current state of Bluetooth, including whether it is enabled, Discoverable, what paired devices exist and are currently active.
Impact:
Bluetooth is a useful wireless tool that has been widely exploited when configured improperly. The user should have insight into the Bluetooth status.
Solution
In System Preferences: Bluetooth, turn Show Bluetooth Status In Menu Bar on.
Alternatively run the following in the command line:
defaults write com.apple.systemuiserver menuExtras -array-add ‘/System/Library/CoreServices/Menu Extras/Bluetooth.menu’
If the remediation is run multiple times multiple instances of the Bluetooth status will appear after rebooting the system. Command-click and drag the unwanted icons off the menu bar
