| Abstract | System assurance is the justified confidence that a system functions as intended and is free of exploitable vulnerabilities, either intentionally or unintentionally designed or inserted as part of the system at any time during the life cycle. The computation and communication backbone of Internet of Things (IoT) devices and other cyber-physical systems (CPS) makes them vulnerable to classes of threats previously not relevant for many physical control and computational systems. The design of resilient IoT systems encompasses vulnerabilities to adversarial disruption (Security), behavior in an operational environments (Function), and increasing interdependencies (Connectedness). System assurance can be met only through a comprehensive and aggressive systems engineering approach. Engineering methods to "design in" security have been explored in the United States through two separate research programs, one through the Systems Engineering Research Center (SERC) and one through the Defense Advanced Research Process Agency (DARPA). This paper integrates these two programs and discusses how assurance practices can be improved using new system engineering and system design strategies that rely on both functional and formal design methods. |
