A Whistle-stop Tour of Ontology-based Solutions to Improve Situational Awareness for a Dull, Dirty, Diverse IoT

Mark Hartong
Click for Abstract

The Internet of Things is already an awkward, overly confident adolescent learning to get along with the rest of computing society. When a 2005 paper asking for “Sympathy for the Sensor Network Debugger” was presented (Ramanathan et al., 2005), Juniper Network’s recent estimate of 38 billion connected things would have seemed farfetched. IoT is not new. The old: closed real time sensor-edge networks, distributed computing, loosely coupled heterogeneous networks, bridge-building across disparate domains, software that reasons about real world events. But a lot is new. Streaming data platforms (Paypal, Prometheus, [] cite more), software-defined networks, ready access to cloud-based reasoning APIs. In this talk we take a whistle-stop tour of use cases around a single family of sensors: the smart humidistat (e.g, Ecobee Si, Honeywell VisionPro and FocusPro). We identify the issues raised by the use case family and suggest aspects of those issues best addressed by ontology-based solutions. We conclude by citing opportunities to integrate ontologies into model-based engineering approaches, highlighting lessons from the 2015 Ontology Summit (Underwood et al., 2015). Domain models are needed for chillers, data centers, refrigeration units http://kbros.co/2bFzBSD . Cross-domain models are needed to “import” external events such as weather or temperature, and to reason about time and duration in terms that make sense for a local context. Manufacturer-supported (or, for widely-adopted consumer products, crowdsourced) models are needed to address subtle, implementation-specific management of battery life, calibration, duty cycle, performance range and maintenance best practices. At the whispered-about edge of the conversation about IoT, ontologies can be integrated with simulation, test and resilience exercises. IoT likely piles a layer of added complexity over nontrivial enterprise applications. Existing software design life cycle (SDLC) practices aren’t much help.

On the Security of Cyber-Physical Systems

Bruno Sinopoli
Click for Abstract

Cyber Physical Systems (CPS) refer to the embedding of widespread sensing, computation, communication, and control into physical spaces. Application areas are as diverse as aerospace, chemical processes, civil infrastructure, energy, manufacturing and transportation, most of which are safety-critical. The availability of cheap communication technologies such as the internet makes such infrastructures susceptible to cyber security threats, which may affect national security as some of them, such as the power grid, are vital to the normal operation of our society. Any successful attack may significantly hamper the economy, the environment or may even lead to loss of human life. As a result, security is of primary importance to guarantee safe operation of CPS.

In an offensive perspective, attacks of this sort can be carried out to disrupt the functionality of the enemy's critical infrastructures without destroying it or even be directly identified. Stuxnet, the malware at the root of the destruction of centrifuges employed to enrich uranium in Iran's nuclear facilities, is a clear example of how strategically important it is to gain a deep understanding of CPS security. In this talk, I will provide an introduction to CPS security, give an overview of recent results from our research group as well as directions for future work.

Dr. Bruno Sinopoli received the Dr. Eng. degree from the University of Padova in 1998 and his M.S. and Ph.D. in Electrical Engineering from the University of California at Berkeley, in 2003 and 2005 respectively. After a postdoctoral position at Stanford University, Dr. Sinopoli joined the faculty at Carnegie Mellon University where he is an associate professor in the Department of Electrical and Computer Engineering with courtesy appointments in Mechanical Engineering and in the Robotics Institute and co-director of the Smart Infrastructure Institute, a research center aimed at advancing innovation in the modeling analysis and design of smart infrastructure. Dr. Sinopoli was awarded the 2006 Eli Jury Award for outstanding research achievement in the areas of systems, communications, control and signal processing at U.C. Berkeley, the 2010 George Tallman Ladd Research Award from Carnegie Mellon University and the NSF Career award in 2010.

Advances in very large-scale integration and microelectromechanical system technology have boosted the development of micro sensor integrated systems. Such systems combine computing, storage, radio technology, and energy source on a single chip. When distributed over a wide area, networks of these embedded devices can perform a variety of tasks that range from environmental monitoring and military surveillance, to navigation and control of a moving vehicle.

A common feature of these systems is the presence of significant communication delays and data loss across the network. From the point of view of control theory, significant delay is equivalent to loss, as data needs to arrive to its destination in time to be used for control. In short, communication and control become tightly coupled such that the two issues cannot be addressed independently. Bruno Sinopoli's research interest focuses on the analysis and design of networked embedded control systems, with applications to sensor actuators networks.

The Unbearable Lightness in the Meaning of Cyber Risk

Dr. Alexander Kott

Click for Abstract

The term "cyber risk" aims to characterize a variety of phenomena where information assets are subject to a potential damage due to cyber attacks. Many attempts, almost unblemished by success, have been made to define cyber risk. In this talk we explore why the concept of cyber risk, as treated by both practitioners and researchers of cybersecurity, is largely inconsistent with definitions of cyber risk commonly offered in the literature. Unsurprisingly, an adequate ontology of cyber risk is lacking; and a rigorous re-conceptualization of cyber risk is needed.

A new formal treatment of cyber risk that should include an ontology of cyber risk-related concepts, a rigorous mathematical model, and practical definitions, all of which must align with common sense perceptions of cyber risk by cybersecurity practitioners. Furthermore, cyber risk belongs firmly to the realm of adversarial decision-making and has little meaning outside of a process geared toward decisions made under extreme uncertainty, time pressure, and under threat of an adversarial actions pre-empting and counteracting those of the defenders. Modeling of risk must be adversarial in nature, with game-theoretic and decision-theoretic perspectives duly considered. And to add to the confusion, we must discuss how inseparably connected yet different are cyber risk and cyber resilience.

Resilent Power Grids

James Momoh
Click for Abstract

Smart grid system deployment has been a major point of concern and interest in the development of the future electric grid both here in the US and abroad. Variety of definitions, semantics, interpretations of its functionality have been given by designers, implementers, end users, standard and security organizations and university communities. Several functions and applications have been proposed in the electric power industry and other related fields have yet to be properly measured by the designers.

To ensure that the capability of smart grid and its functionality are understood generally stakeholders need performance metric such as resilience, sustainability and reliability and efficiency to measure its deployment.

In this presentation we plan to provide a working definition, architecture and test beds in common use as well as define some of the functionality of smart grid for its deployment in the 21st century for the development of future electric grid.

Further, we will address the grand challenge problems and options for assessing the overall performance of the future grid, which will include identification of unified knowledge from different disciplines to address some of the challenge problems, will be highlighted in the presentation.

On going research activities and open research questions to further improve the high performance smart grid, which will be of value to university researchers, developers and policy makers will be discussed.
