Verify TOSS 5 disables the graphical user interface autorun function using the following command:
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.
$ 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.
