Fix Recommendation

Configure the GNOME desktop to not allow a user to change the setting that disables autorun on 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/autorun-never

Then update the dconf system databases:

$ sudo dconf update

Check Contents

Note: This requirement assumes the use of the RHEL 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 RHEL 9 disables ability of the user to override the graphical user interface autorun setting.

Check that the autorun setting is set to prevent user modification with the following command:

$ gsettings writable org.gnome.desktop.media-handling autorun-never

false

If "autorun-never" is writable, the result is "true". If this is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
