Matt Mickelson, "Physics-Based Approaches for creating Cyber Resilient Systems"

Our reliance on Cyber-Physical Systems (CPS) is growing. As CPS
infrastructure becomes exposed to the contested world through
networks, CPS security becomes much more important. In a CPS, the
cyber components manage the physical components. We propose that
the overall goal for CPS resiliency is to have the physical systems
behave properly regardless of fault and disruption. Our approach to
CPS resiliency focuses on the physical components. Specifically,
the inertia of the physical components provide a natural but
limited resilience, and is capable of tolerating short-term
disruption without affecting the health and safety of the CPS. This
and the fact CPS have a large difference between physical and cyber
time scales, enables a unique approach to CPS resiliency. This talk
will present our approach of engineering the cyber components to be
brittle against attack, which consequently forces cyber attacks and
related disruptions to be short-lived and within tolerance of the
physical system’s inertia.
