Data collection method for security digital twin on cyber physical systems

Abstract

Through the progress of Digital Twin technology and subsequent realization of Cyber-Physical Systems (CPS), the threat of cyber attacks to those systems is rising. Due to differing requirements in Operational Technology (OT) systems, existing IT security is insufficient to secure CPS. To overcome these challenges, we are developing a highly modular Security Digital Twin (SDT), targeting a wide variety of OT/IoT use-cases and scenarios. Due to its modular design, a naïve implementation of required data collection is highly cost-inefficient; to address this, a data collection abstraction layer for the SDT is proposed, utilizing upper layer data requirements through a unified interface. In a qualitative evaluation, the proposed solution is shown to be cost-effective.
