Solving Defender-Attacker-Defender Models for Infrastructure Defense

This paper (a) describes a defender-attacker-defender sequential game model (DAD) to plan defenses for an infrastructure system that will enhance that system’s resilience against attacks by an intelligent adversary, (b) describes a realistic formulation of DAD for defending a transportation network, (c) develops a decomposition algorithm for solving this instance of DAD and others, and (d) demo...

Optimal power grid protection through a defender-attacker-defender model

Power grid vulnerability is a major concern of our society, and its protection problem is often formulated as a tri-level defender-attacker-defender model. However, this tri-level problem is computationally challenging. In this paper, we design and implement a Column-and-Constraint Generation algorithm to derive its optimal solutions. Numerical results on an IEEE system show that: (i) the devel...

Defender Personality Traits

The security community has used psychological research on attacker personalities, but little work has been done to investigate the personalities of the defenders. One instrument currently dominating personality research is the Five Factor Model, a taxonomy that identifies five major domains of personal traits, composed of sets of facets. This model can be used within an organizational or vocati...

The Public Defender as International Transplant

The last quarter century has seen countries across Latin America and other parts of the world dramatically transition from an inquisitorial criminal justice system to an adversarial system. As a part of this shift in adjudication, these systems have adopted a key component of the adversarial system: the public defender. But while the formal and structural changes in these systems have been prof...
