Additional techniques include time-synchronous or challenge-response one-time authenticators.Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163, SRG-OS-000480-GPOS-00227
Solution
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
