Detector IDs Bugs by Monitoring Power Use

摘要

Malware is evasive, intelligent, and sneaky. No sooner than antivirus software is updated to combat the latest attacks, a computer virus already will have evolved into something harder to detect and potentially more damaging to a computer system.Malware. though, is not without vulnerabilities. Engineers at the University of Texas, Austin, and North Carolina State University, Raleigh, have found an additional line of defense to detect threats that does not rely on the detection and protection provided by existing antivirus software programs. Their method detects the presence of malware in large-scale embedded computer systems by monitoring power usage and identifying unusual surges as signs of unwelcome security threats.
