Note: If the operating system does not have a graphical user interface installed, this requirement is Not Applicable. Verify the operating system disables the ability to automount devices in a graphical user interface. Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". This path must be modified if a database other than "local" is being used. Check to see if automounter service is disabled with the following commands: # cat /etc/dconf/db/local.d/00-No-Automount [org/gnome/desktop/media-handling] automount=false automount-open=false autorun-never=true If the output does not match the example above, this is a finding. # cat /etc/dconf/db/local.d/locks/00-No-Automount /org/gnome/desktop/media-handling/automount /org/gnome/desktop/media-handling/automount-open /org/gnome/desktop/media-handling/autorun-never If the output does not match the example, this is a finding. |
