1. An Internet of Things Testbed for Education and Community Research

   Swaim, John; Workman, Chad; Di, Jia; Du, Xiaojiang (September 2023, IEEE International Conference on Artificial Intelligence, Blockchain, and Internet of Things)

   The testbed presented in this study supplies various devices to emulate a smart home. The paper highlights how devices can be connected and programmed to perform functions using an application programming interface. Remote-controlled robots in the testbed enable a user to manipulate, monitor, and configure home-based Internet-of-Things (IoT) technologies. The paper describes the equipment used in the testbed, including a wireless security camera, a smart lock, a climate sensor, and two types of robots. Security measures implemented in the testbed are also discussed. Several application scenarios are presented and analyzed on how they were accomplished to demonstrate the functionalities. The smart home testbed is a useful resource for education and development, as it allows for sufficient performance using a single control point.

2. Triton: A Software-Reconfigurable Federated Avionics Testbed

   Crow, Sam; Farinholt, Brown; Johannesmeyer, Brian; Koscher, Karl; Checkoway, Stephen; Savage, Stefan; Schulman, Aaron; Snoeren, Alex C; Levchenko, Kirill (August 2019, USENIX Workshop on Cyber Security Experimentation and Test (CSET))

   This paper describes the Triton federated-avionics security testbed that supports testing real aircraft electronic systems for security vulnerabilities. Because modern aircraft are complex systems of systems, the Triton testbed allows multiple systems to be instantiated for analysis in order to observe the aggregate behavior of multiple aircraft systems and identify their potential impact on flight safety. We describe two attack scenarios that motivated the design of the Triton testbed: ACARS message spoofing and the software update process for aircraft systems. The testbed allows us to analyze both scenarios to determine whether adversarial interference in their expected operation could cause harm. This paper does not describe any vulnerabilities in real aircraft systems; instead, it describes the design of the Triton testbed and our experiences using it. One of the key features of the Triton testbed is the ability to mix simulated, emulated, and physical electronic systems as necessary for a particular experiment or analysis task. A physical system may interact with a simulated component or a system whose software is running in an emulator. To facilitate rapid reconfigurability, Triton is also entirely software reconfigurable: all wiring between components is virtual and can be changed without physical access to components. A prototype of the Triton testbed is used at two universities to evaluate the security of aircraft systems.

3. Combining Power Simulation and Programmable Network Emulation for Smart Grid Security Application Evaluation

   https://doi.org/10.1145/3573900.3593633  

   Chen, Gong; Hu, Zheng; Qu, Yanfeng; Jin, Dong (June 2023, ACM SIGSIM Conference on Principles of Advanced Discrete Simulation (PADS), June 2023)

   We present a unique virtual testbed that combines a data-plane programmable network emulator and a power distribution system simulator to evaluate smart grid security and resilience applications. The testbed employs a virtual time system for effective simulation synchronization and fidelity enhancement. We showcase the advantages of the simulation testbed through an anomaly detection case study.

4. Cybersecurity threats and experimental testbed for a generator system

   https://doi.org/10.1177/1548512920960537  

   Werth, Aaron W; Griffith, SueAnne N; Hairston, Jesse R; Morris, Thomas H (January 2022, The Journal of Defense Modeling and Simulation: Applications, Methodology, Technology)

   In this work, a high-fidelity virtual testbed modeling a networked diesel generator, similar to those used commercially and by the military, is described. This testbed consists of a physical system model of a generator, a digital control system, a remote monitoring system, and physical and networked connections. The virtual testbed allows researchers to emulate a cyber-physical system and perform cyber attacks against the system without the monetary and safety risks associated with a testbed created from physical components. The testbed was used to feasibly simulate network, hardware Trojan, and software Trojan attacks against the diesel generator, and to observe the cyber and physical outcomes.

5. Transpacific Testbed for Real-Time Experimentation

   https://doi.org/10.1109/5GWF52925.2021.00095

   null (Ed.)

   The transpacific testbed is a generic routing encapsulation (GRE) tunnel built between CUNY City College (CCNY), USA and Kyushu Institute of Technology (KYUTECH), Japan. The tunnel, built through internet2, originated from CCNY through the JGN network in Seattle and terminated at Kyutech in Japan. The testbed defines the future of the Internet by focusing on addressing research challenges associated with enabling trustworthy networks, supporting the Internet of Things (IoT), which encompasses everything connected to the Internet and cyber-physical systems (CPS) - a controlled mechanism monitored by computer-based algorithms. In this paper, we describe the setting up and testing of the testbed. Furthermore, we describe the real-time experiments conducted on the testbed and present the results. The experiments are classified into two: blockchain-based cooperative intrusion detection system (CoIDS) and Secure Virtual Machine introspection. In each of the experiments, we describe the method and present the results. Finally, we look into the ongoing works of extending the testbed to the COSMIC global testbed.
