The Computer Security Threat From Ultrasonic Networks
- lsh123 12y ago“The concept of a covert acoustical mesh network renders many conventional security concepts useless” I am curious how much real security expertise the quoted researches have. Conventional security measures would work great with this new communication layer: removing speakers/mics will be as effective as removing a network card/usb ports/floppy drives which is a common technique for protecting sensitive computers and data (and it is known for ages). Same goes to access control (who can listen to speakers or use network card). Same goes to firewalls (stop unexpected traffic or unexpected sound). And the list goes on and on.
