Intelligent Software CPS Resiliency Evaluation and Mitigation (iSCream)

While networked systems are becoming increasingly critical to the operations and efficiency of Industrial Control Systems (ICS), such as in Columbia Class Hull Mechanical and Electrical Systems, they also make the ICS systems susceptible to cyber physical attacks that could impact system performance or have catastrophic consequences. Software modeling of the ICS and associated processes and operations provides an easy-to-use and efficient method to assess the cyber resilience of the Cyber Physical System (CPS) infrastructure and to identify and mitigate risks in a cost-efficient manner. SCALABLE proposes to develop an ICS resiliency modeling tool called Intelligent Software CPS Resiliency Evaluation and Mitigation (iSCream). iSCream is being developed to efficiently model existing CPS systems-of-systems including technology, processes, cyber attacks and their impact. iSCream will model the configuration, topology, traffic load and dynamics of military ICS at sufficient fidelity to accurately reproduce the behavior of the physical system. These software models will be scalable to a large number of network and infrastructure devices and real-word application traffic. iSCream’s comprehensive device and cyber physical model library, ability to integrate with live software/hardware components and live operators will provide the means to efficiently assess realistic operational scenarios.
