Query: Spatial-Temporal Moving Target Defense: A Markov Stackelberg Game Model   Moving target defense has emerged as a critical paradigm of protecting a
vulnerable system against persistent and stealthy attacks. To protect a system,
a defender proactively changes the system configurations to limit the exposure
of security vulnerabilities to potential attackers. In doing so, the defender
creates asymmetric uncertainty and complexity for the attackers, making it much
harder for them to compromise the system. In practice, the defender incurs a
switching cost for each migration of the system configurations. The switching
cost usually depends on both the current configuration and the following
configuration. Besides, different system configurations typically require a
different amount of time for an attacker to exploit and attack. Therefore, a
defender must simultaneously decide both the optimal sequences of system
configurations and the optimal timing for switching. In this paper, we propose
a Markov Stackelberg Game framework to precisely characterize the defender's
spatial and temporal decision-making in the face of advanced attackers. We
introduce a relative value iteration algorithm that computes the defender's
optimal moving target defense strategies. Empirical evaluation on real-world
problems demonstrates the advantages of the Markov Stackelberg game model for
spatial-temporal moving target defense.
