ISAAC: The Idaho CPS Smart Grid Cybersecurity Testbed

Abstract: The landscape of cyber and other threats to Cyber Physical Systems (CPS), such as the Power Grid, is growing rapidly. Realistic and reconfigurable testbeds are needed to be able to develop, test, improve, and deploy practical cybersecurity solutions for CPS. We introduce the design of ISAAC, the Idaho CPS Smart Grid Cybersecurity Testbed. ISAAC is a cross-domain, distributed, and reconfigurable testbed, which emulates a realistic power utility and provides researchers with the tools needed to develop and test integrated cybersecurity solutions. Some components of ISAAC are fully functional, with ongoing research projects utilizing the functional components. When fully developed, the capabilities of ISAAC will include: 1) Multiple emulated power utility substations and control networks; 2) Emulating wide-area power transmission and distribution systems, 3) Emulated SCADA control centers, 4) Advanced visualization and cyber-analytics, including machine learning. ISAAC will enable the development, testing, evaluation, and validation of holistic cyber-physical security approaches for cyber physical systems and the Smart Grid. We hope that our endeavor, ISAAC, will help further the boundaries of CPS research and education.

Experimental evaluation of two open source solutions for wireless mesh routing at layer two

Abstract: The paper reports the outcome of an experimental evaluation of two open source solutions for realising a Wireless Mesh Network (WMN). Both works at layer two of the ISO/OSI stack and are transparent to the IP layer, i.e. they allow keeping the existing TCP/IP stack unchanged and avoid dealing with the complex IP configuration and management tasks. The first solution is the upcoming IEEE 802.11s standard, as implemented by the open 80211s project, and the other is the B.A.T.M.A.N. routing protocol, in its layer-2 version. We compared them in a small experimental testbed, with main focus on their behaviour in typical mesh situations. We found that both have strengths and shortcomings, but none can be claimed to be completely mature.

FireSenseTB: a wireless sensor networks testbed for forest fire detection

Abstract: Wireless sensor networks promise great success in many areas from environmental monitoring to medical and military applications. Forest fire detection is one of these areas where many of the ongoing WSN research is focused today. Unfortunately, most of these studies choose simulating their proposed solutions instead of doing experiments in real testbed environments, since that kind of setup exposes additional difficulties. Our previous work, named FireSense, proposed a fire detection algorithm, which was shown to be successful in terms of simulation results.In this study, we take FireSense to a real outdoor testbed for further analysis of its effectiveness in terms of various parameters such as link and node failures, topology and physical configuration changes, wind direction, ignition point position and sampling period variations.

A highly flexible digital radio testbed and 60 GHz application examples

Abstract: In this paper we present a modular digital radio testbed, which has been developed to enable the implementation of novel wireless transmission concepts and signal processing algorithms The highly flexible and reconfigurable hardware comprises a commercial FPGA platform, a self-developed converter board as well as various plug-on clock and RF modules To illustrate the capabilities of the testbed, two application examples are presented: real-time channel sounding and 60 GHz point-to-point transmission with higher order modulation

SDN based testbeds for evaluating and promoting multipath TCP

Abstract: Multipath TCP is an experimental transport proto- col with remarkable recent past and non-negligible future poten- tial. It has been standardized recently, however the evaluation studies focus only on a limited set of isolated use-cases and a comprehensive analysis or a feasible path of Internet-wide adoption is still missing. This is mostly because in the current networking practice it is unusual to configure multiple paths between the endpoints of a connection. Therefore, conducting and precisely controlling multipath experiments over the real "inter- net" is a challenging task for some experimenters and impossible for others. In this paper, we invoke SDN technology to make this control possible and exploit large-scale internet testbeds to conduct end-to-end MPTCP experiments. More specifically, we establish a special purpose control and measurement framework on top of two distinct internet testbeds. First, using the OpenFlow support of GEANT, we build a testbed enabling measurements with real traffic. Second, we design and establish a publicly available large-scale multipath capable measurement framework on top of PlanetLab Europe and show the challenges of such a system. Furthermore, we present measurements results with MPTCP in both testbeds to get insight into its behavior in such not well explored environment. Index Terms—GEANT, PlanetLab, OpenFlow, Multipath TCP
