OL 9 must disable the graphical user interface autorun function unless required.

Allowing autorun commands to execute may introduce malicious code to a system. Configuring this setting prevents autorun commands from executing.

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 the graphical user interface autorun function with the following command: $ gsettings get org.gnome.desktop.media-handling autorun-never true If "autorun-never" is set to "false", and is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.

Configure the GNOME desktop to disable the autorun function on removable media. The dconf settings can be edited in the /etc/dconf/db/* location. Update the [org/gnome/desktop/media-handling] section of the "/etc/dconf/db/local.d/00-security-settings" database file and add or update the following lines: [org/gnome/desktop/media-handling] autorun-never=true Update the dconf system databases: $ sudo dconf update
