Query: Proactive Population-Risk Based Defense Against Denial of Cyber-Physical
  Service Attacks   While the Internet of things (IoT) promises to improve areas such as energy
efficiency, health care, and transportation, it is highly vulnerable to
cyberattacks. In particular, DDoS attacks work by overflowing the bandwidth of
a server. But many IoT devices form part of cyber-physical systems (CPS).
Therefore, they can be used to launch a "physical" denial-of-service attack
(PDoS) in which IoT devices overflow the "physical bandwidth" of a CPS. In this
paper, we quantify the population-based risk to a group of IoT devices targeted
by malware for a PDoS attack. To model the recruitment of bots, we extend a
traditional game-theoretic concept and create a "Poisson signaling game." Then
we analyze two different mechanisms (legal and economic) to deter botnet
recruitment. We find that 1) defenders can bound botnet activity and 2)
legislating a minimum level of security has only a limited effect, while
incentivizing active defense can decrease botnet activity arbitrarily. This
work provides a quantitative foundation for designing proactive defense against
PDoS attacks.
