BG-FlipIn: A Bayesian Game Framework for FlipIt-Insider Models in Advanced Persistent Threats

Published
Record updated

Summary

This paper proposes BG-FlipIn, a three-player Bayesian game framework for FlipIt-insider models of advanced persistent threats, covering malicious, inadvertent and corrupt insiders. The authors derive a closed-form Bayesian Nash Equilibrium and Nash Equilibria for three deterministic edge cases. Three applications show the defender can make consistent decisions without detecting the insider's specific preference.
