Abstract

It is well known that not all intrusions can be prevented and additional lines of defense are needed to deal with intruders. However, most current approaches use honeynets relying on the assumption that simply attracting intruders into honeypots would thwart the attack. In this paper, we propose a different and more realistic approach, which aims at delaying intrusions, so as to control the probability that an intruder will reach a certain goal within a specified amount of time. Our method relies on analyzing a graphical representation of the computer network's logical layout and an associated probabilistic model of the adversary's behavior. We then artificially modify this representation by adding "distraction clusters" - collections of interconnected virtual machines - at key points of the network in order to increase complexity for the intruders and delay the intrusion. We study this problem formally, showing it to be NP-hard and then provide an approximation algorithm that exhibits several useful properties. Finally, we present experimental results obtained on a prototypal implementation of the proposed framework.
