Vulnerability discussion

A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not want to log out because of the temporary nature of the absence.The session lock is implemented at the point where session activity can be determined.Regardless of where the session lock is determined and implemented, once invoked, the session lock must remain in place until the user reauthenticates. No other activity aside from reauthentication must unlock the system.

Check content

To check if the Bluetooth Remote Wake setting is disabled, run the following two commands as the primary user: /usr/bin/defaults -currentHost read com.apple.Bluetooth RemoteWakeEnabled /usr/bin/defaults read /Users/`whoami`/Library/Preferences/ByHost/com.apple.Bluetooth.`/usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c22-57`.plist RemoteWakeEnabled If there is an error or nothing is returned, or the return value is "1" for either command, this is a finding.

Fix text

Manually change this control on the computer by opening System Preferences >> Bluetooth. Click "Advanced" and ensure the "Allow Bluetooth devices to wake this computer" is not checked. This control is not necessary if Bluetooth has been completely disabled. The following can be run from the command line to disable "Remote Wake" for the current user: /usr/bin/defaults write /Users/`whoami`/Library/Preferences/ByHost/com.apple.Bluetooth.`/usr/sbin/system_profiler SPHardwareDataType | /usr/bin/grep "Hardware UUID" | /usr/bin/cut -c22-57`.plist RemoteWakeEnabled 0

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
