Fix Recommendation

Configure the GNOME desktop to disable automated mounting of 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]
automount-open=false

Update the dconf system databases:

$ sudo dconf update

Check Contents

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 automount function with the following command:

$ gsettings get org.gnome.desktop.media-handling automount-open
false

If "automount-open" is set to "true", and is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
