Threats from inside: Dynamic utility (Mis)alignments in an agent based model

We envision a game theoretic model of an organization so as to devise new mechanisms to improve compliance and reduce various insider threats - be it intentional or unintentional, while paying proportional attention to various intertwined issues: namely in the form of deception, privacy, trust, global utilities and stability. For this purpose, we primarily rely on a realistic formulation of classical information-asymmetric signaling games, in a repeated form, while allowing the agents to dynamically vary their strategic choices as their utilities get (mis)aligned. To better understand the multifaceted security concerns in existing and emerging multi-agent interactions within an organization, we map, model and analyze various challenging scenarios of threats: namely, those by design or those by negligence. We also describe a bridge to the future by investigating the extendability of the proposed mechanisms in a specific embodiment, where available meta-data is mined to model behavioral propensities of the agents. Simulation and empirical analysis indicate promising results for this approach to deliver new mechanisms and control regimes.
