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.

Dual Use SDN Controller for Management and Experimentation in a Field Deployed Testbed
Abstract: An SDN controller is developed for both testbed management and experimentation for the optical x-haul network in the COSMOS testbed providing a service-on-demand and
reconfigurable platform for 5G wireless experiments coupled with edge cloud services.

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.more » « less

This paper presents Virginia Tech’s wireless testbed supporting research on long-term evolution (LTE) signaling and radio frequency (RF) spectrum coexistence. LTE is continuously refined and new features released. As the communications contexts for LTE expand, new research problems arise and include operation in harsh RF signaling environments and coexistence with other radios. Our testbed provides an integrated research tool for investigating these and other research problems; it allows analyzing the severity of the problem, designing and rapidly prototyping solutions, and assessing them with standard-compliant equipment and test procedures. The modular testbed integrates general-purpose software-defined radio hardware, LTE-specific test equipment, RF components, free open-source and commercial LTE software, a configurable RF network and recorded radar waveform samples. It supports RF channel emulated and over-the-air radiated modes. The testbed can be remotely accessed and configured. An RF switching network allows for designing many different experiments that can involve a variety of real and virtual radios with support for multiple-input multiple-output (MIMO) antenna operation. We present the testbed, the research it has enabled and some valuable lessons that we learned and that may help designing, developing, and operating future wireless testbeds.more » « less

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.more » « less
