  We consider the future cyber security of industrial control systems. As best
as we can see, much of this future unfolds in the context of the Internet of
Things (IoT). In fact, we envision that all industrial and infrastructure
environments, and cyber-physical systems in general, will take the form
reminiscent of what today is referred to as the IoT. IoT is envisioned as
multitude of heterogeneous devices densely interconnected and communicating
with the objective of accomplishing a diverse range of objectives, often
collaboratively. One can argue that in the relatively near future, the IoT
construct will subsume industrial plants, infrastructures, housing and other
systems that today are controlled by ICS and SCADA systems. In the IoT
environments, cybersecurity will derive largely from system agility,
moving-target defenses, cybermaneuvering, and other autonomous or
semi-autonomous behaviors. Cyber security of IoT may also benefit from new
design methods for mixed-trusted systems; and from big data analytics --
predictive and autonomous.
