CoFacS Complete Factory Simulation for Security Research

This document is a technical report that presents CoFacS, a comprehensive simulation of an industrial factory designed to study the security of interconnected production systems. The report outlines the vulnerabilities of digitized factories to cyber-attacks and highlights the limitations of existing testbeds that typically focus on individual components rather than entire production lines. CoFacS aims to fill this gap by providing a complete simulation that integrates real-life industrial applications, allowing researchers to evaluate the impact of cyber-attacks and the effectiveness of security measures in an end-to-end manner. The authors validate CoFacS against a physical model factory, demonstrating its accuracy with a maximum deviation of 0.11%. The report details the contributions of CoFacS, including its ability to simulate physical processes, control components, and network communication, while also showcasing its application in case studies related to attack detection and the resilience of 5G-based industrial communication against jamming. Overall, CoFacS serves as a vital tool for advancing security research in industrial control systems.
