Moving-target Defense

The goal of this research is to understand and quantify the potential and limitations of moving-target defense (MTD) systems to protect computer networks. To achieve this goal, we are building a fully functional prototype MTD system that will automatically adapt multiple aspects of the network's logical and physical configuration. We also plan to (1) create a set of analytical models to quantify the effectiveness of MTD systems, and (2) address key research questions such as how an MTD system's effect can be measured in terms of security gain and mission impact, what are the key parameters of an MTD system, whether an MTD system that can adapt multiple configuration aspects is feasible for reasonable threat assumptions, and whether an intelligent MTD triggered by attack/risk indicators can be more effective than a purely random MTD.
