Reclaiming Bus-based Systems During Compromise (Red-C) seeks to explore algorithms to construct self-healing systems, by retrofitting firmware for individual components on a bus to function as forensic sensors that collectively monitor peers to detect, repair, and inoculate on-system during a cyber-attack. Many Department of Defense critical systems are bus-based systems with implicitly trusted modular components. Bus-based systems are currently vulnerable to cascading implicit trust attacks, and system recovery is hindered by the lack of available forensic information. The Red-C program will construct a resilient approach to on-system detection and repair of cyber-attacks which can be implemented on current hardware via firmware updates ending the lack of state data and the cascading implicit trust flaw in modern buses.
