TOSS 5 must prevent a user from overriding the disabling of the graphical user interface automount function.

A nonprivileged account is any operating system account with authorizations of a nonprivileged user. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163

Verify TOSS 5 disables ability of the user to override the graphical user interface automount setting. Note: This requirement assumes the use of the TOSS 5 default graphical user interface—the GNOME desktop environment. If the system does not have a graphical user interface installed, this requirement is not applicable. Determine which profile the system database is using by running the following command: $ sudo grep system-db /etc/dconf/profile/user system-db:local Verify the automount setting is locked from nonprivileged user modification using the following command: Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". Modify this path if using a database other than "local". $ 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
