“Despite the costs, many in the cybersecurity establishment are slowly coming around to the potential of analog defenses. Last September, Darpa launched the $36 million Leveraging the Analog Domain for Security (LADS) program, which is attempting to create a set of electronic ears that can detect malicious activity by monitoring the unintentional analog emissions of digital hardware, such as heat, sound, and changed frequencies. ‘The advantage of an analog approach is that there’s no way for the malware to directly reach through air and affect the monitoring device,’ says Angelos Keromytis, who runs the program.”
