WIP: Cyber Security Measurement Taking Physical Circumstances

This paper proposes an architecture that supports security measures by evaluating the impact of cyber attacks on physical spaces, utilizing information gathered from the neighborhoods of devices. The architecture includes digital twin (DT) models that represent the conditions of physical spaces in cyberspace and utilizes various types of information in both cyber and physical spaces, such as device location, speed, and vulnerability, for cyber-physical security measures. We summarize the challenges in translating security information into DT models and in implementing the overall architecture for security measurements.
