Cyber Fault-tolerant Attack Recovery (CFAR)
Abstract
The Cyber Fault-tolerant Attack Recovery (CFAR) program developed novel architectures to achieve cyber fault-tolerance with commodity computing technologies. 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 combined techniques for detecting differences across functionally replicated systems with novel variants that exhibit differences in behavior under cyber attack, so that CFAR-enabled computing systems can quickly detect deviations in processing elements at attack onset and rapidly reboot to restore affected services. CFAR technologies were developed in coordination with operational users.
