Description:
By default GNOME automatically mounts removable media when inserted as a convenience to the user.
Rationale:
With automounting enabled anyone with physical access could attach a USB drive or disc and have its contents available in system even if they lacked permissions to mount it themselves.
Fix:
Edit or create the file /etc/dconf/db/local.d/00-media-automount and edit or add the following:
[org/gnome/desktop/media-handling]
automount=false
automount-open=false
And run the following command to update dconf database:
# dconf update
Parameter:
[yes/no]
Technical Mechanism:
Edit or create the file /etc/dconf/db/local.d/00-media-automount and edit or add the following:
[org/gnome/desktop/media-handling]
automount=false
automount-open=false
And run the following command to update dconf database:
# dconf update
