ABSTRACT
This chapter presents the basic methodologies and state-of-the-art techniques on Graphical Security Models (GrSMs) and Intrusion Response Systems (IRSs) for modeling and responding to cyber-attacks. A GrSM is a basic methodology for representing and studying the interactions between a defender and an attacker in a cyber-attack scenario. Here, we present the basic references in the related literature and discuss their basic pros and cons. Then, we present the basic state-of-the-art research efforts on dynamic IRSs for automated intrusion response. Such models identify potential threats and react to cyber-attacks in a dynamic and automated fashion in real time to ensure security. Finally, we draw a connection between GrSMs and IRSs by highlighting the suitability of the various GrSMs for the deployment of a dynamic IRS.
