Query: Markov Game Modeling of Moving Target Defense for Strategic Detection of
  Threats in Cloud Networks   The processing and storage of critical data in large-scale cloud networks
necessitate the need for scalable security solutions. It has been shown that
deploying all possible security measures incurs a cost on performance by using
up valuable computing and networking resources which are the primary selling
points for cloud service providers. Thus, there has been a recent interest in
developing Moving Target Defense (MTD) mechanisms that helps one optimize the
joint objective of maximizing security while ensuring that the impact on
performance is minimized. Often, these techniques model the problem of
multi-stage attacks by stealthy adversaries as a single-step attack detection
game using graph connectivity measures as a heuristic to measure performance,
thereby (1) losing out on valuable information that is inherently present in
graph-theoretic models designed for large cloud networks, and (2) coming up
with certain strategies that have asymmetric impacts on performance. In this
work, we leverage knowledge in attack graphs of a cloud network in formulating
a zero-sum Markov Game and use the Common Vulnerability Scoring System (CVSS)
to come up with meaningful utility values for this game. Then, we show that the
optimal strategy of placing detecting mechanisms against an adversary is
equivalent to computing the mixed Min-max Equilibrium of the Markov Game. We
compare the gains obtained by using our method to other techniques presently
used in cloud network security, thereby showing its effectiveness. Finally, we
highlight how the method was used for a small real-world cloud system.
