Architecting cyber-secure, resilient system-of-systems

Abstract

The DoD system-of-systems (SoS) relies heavily on cyberspace operations. The latter tend to be vulnerable to a variety of disruptions. These disruptions can be from within or outside the SoS. The ability to withstand disruptions is essential to maintaining a competitive edge in terms of freedom of maneuver afforded by cyberspace. Since impenetrable cyberspace capacity is implausible, architecting for cyber-resilience has become a national imperative. This paper explores the complexity of cybersecurity and ways to achieve cyber-resilience that is informed by cyber strategies and techniques developed within a modelbased engineering framework.
