[ISN] Startup finds malware intrusions by keeping an eye on processor radio frequencies

PFP’s system compares ongoing radio-frequency output from processors to a baseline that is established when the device is known to be performing legitimate tasks. When it detects anomalies that might represent malicious activity, it triggers alarms. Then it’s up to other tools to figure out what exactly is behind the problem. The system could be used to keep an eye on a large number of similar devices all performing the same task, such as those found in supervisory control and data acquisition (SCADA) networks that support power grids, chemical plants and the like. Savannah River National Laboratory is considering the gear for to protect its smart-grid relays. The system could also be used to check new devices as they are delivered from the plants where they are made in order to find faulty ones or ones that have been tampered with, the company says. […]
