CoRT: A Communication Robustness Testbed for Industrial Control System Components
This addresses security vulnerabilities in critical infrastructures and manufacturing, though it is incremental as it builds on existing testbed approaches.
The paper tackles the problem of securing Industrial Control System (ICS) components by introducing a testbed and measurement methods to assess communication robustness, enabling safe testing in a research environment.
The number of interconnected devices is growing constantly due to rapid digitalization, thus providing attackers with a larger attack surface. Particularly in critical infrastructures and manufacturing, where processes can be observed and controlled remotely, successful attacks could lead to high costs and damage. Therefore, it is necessary to investigate Industrial Control System (ICS) devices like Programmable Logic Controllers (PLCs) to make these sectors more secure. One possible attack vector is the exploitation of the network communication of devices. Thus, a robust communication system is essential to ensure security. Unfortunately, the high demand for real-world ICSs makes it difficult to assess component security during its runtime. However, this is possible in a research testbed where tests could be done and analyzed in a safe environment. In this paper, we introduce our testbed and measurement methods for communication robustness test research of ICS components.
