| This requirement assumes the use of the OL 9 default graphical user interface—the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable. Verify that OL 9 disables ability of the user to override the graphical user interface automount setting. Determine which profile the system database is using with the following command: $ grep system-db /etc/dconf/profile/user system-db:local Check that the automount setting is locked from nonprivileged user modification with the following command: 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. $ grep 'automount-open' /etc/dconf/db/local.d/locks/* /org/gnome/desktop/media-handling/automount-open If the command does not return at least the example result, this is a finding. |

| Configure the GNOME desktop to not allow a user to change the setting that disables automated mounting of removable media. Add the following line to "/etc/dconf/db/local.d/locks/00-security-settings-lock" to prevent user modification: /org/gnome/desktop/media-handling/automount-open Update the dconf system databases: $ sudo dconf update |
