Cyber Fault-tolerant Attack Recovery (CFAR)
Abstract
The Cyber Fault-tolerant Attack Recovery (CFAR) program is developing novel architectures to achieve cyber fault-tolerance with commodity computing technologies. Current approaches to handling cyber-induced faults in mission-critical systems are inadequate, as perimeter defenses wrapped around vulnerable monocultures do not scale, while zero-day exploits evade signature-based defenses. The proliferation of processing cores in multi-core central processing units provides the opportunity to adapt fault-tolerant architectures proven in aerospace applications to mission-critical, embedded, and real-time computing systems. The CFAR program will combine techniques for detecting differences across functionally replicated systems with novel variants that guarantee differences in behavior under attack. The resulting CFAR-enabled computing systems will quickly detect deviations in processing elements at attack onset and rapidly reboot to restore affected services.
