Active Crowd Defense

Jeffrey Pawlick, Quanyan Zhu

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter studies an emerging cyberattack called a “physical” denial-of-service (PDoS) attack, in which devices in the Internet of things overflow the “physical bandwidth” of a cyber-physical system. In order to model active defense used against a PDoS attack, we develop a “Poisson signaling game,” a signaling game with an unknown number of receivers, which have varying abilities to detect deception. Equilibrium results indicate that (1) defenders can bound botnet activity and (2) legal approaches to security have only a limited effect, while active defense can decrease botnet activity arbitrarily.
