A Purdue connection informed me of this. A rare practical pointer to Nash equilibrium in game theory. And 'Prospect theory' which I had not heard of. Dealing with aspects of risk. But I see it is what Kahneman's work is called. Taking a closer look.
Game Theory Harnessed for Cybersecurity of Large-Scale Nets
Purdue University News By Emil Venere
Researchers at Purdue University are leading the development of a platform for improving the cybersecurity of large-scale networks by tapping game theory and new intelligent algorithms. Purdue professor Shreyas Sundaram says the team has harnessed Nash equilibrium as well as prospect theory, defining how people make decisions amid uncertainty and risk. Sundaram thinks the work "will lead to a more complete understanding of the vulnerabilities that arise in large-scale interconnected systems and guide us to the design of more secure systems." The team has demonstrated the formulation of an "optimization problem" to efficiently calculate how much a given stakeholder will decide to invest, and they plan to use the "moving-target defense," in which the system can reconfigure itself to lower a repeated cyberattack's success rate. "The project will provide new insights into the types of decisions that humans make when faced with security threats, via a comprehensive approach spanning theory and experiments," says Purdue professor Timothy Cason. ...
