Abstract Research purpose. Smart City technologies offer great promise for a higher quality of life, including improved public services, in an era of rapid and intense global urbanization. The use of intelligent or smart information and communication technologies to produce more efficient systems of services in those urban areas, captured under the broad rubric of “smart cities,” also create new vectors of risk and vulnerability. The aim of this article is to raise consideration of an integrated cross-domain approach for risk reduction based on the risks smart cities are exposed to, on the one hand, from natural disasters and, on the other, from cyber-attacks. Design / Methodology / Approach. This contribution describes and explains the risk profile for which smart cities are exposed to both natural disasters and cyber-attacks. The vulnerability of smart city technologies to natural hazards and cyber-attacks will first be summarized briefly from each domain, outlining those respective domain characteristics. Subsequently, methods and approaches for risk reduction in the areas of natural hazards and ICT security will be examined in order to create the basis for an integrated cross-domain approach to risk reduction. Differences are also clearly identified if an adaptation of a risk reduction pattern appears unsuitable. Finally, the results are summarized into an initial, preliminary integrated cross-domain approach to risk reduction. Findings. Risk management in the two domains of ICT security and natural hazards is basically similar. Both domains use a multilayer approach in risk reduction, both have reasonably well-defined regimes and established risk management protocols. At the same time, both domains share a policymaking and policy implementation challenge of the difficulty of appropriately forecasting future risk and making corresponding resource commitments to address future risk. Despite similarities, different concepts like the CIA Triad, community resilience, absorption capacity and so on exist too. Future research of these concepts could lead to improve risk management. Originality / Value / Practical implications. Cyber-attacks on the ICT infrastructure of smart cities are a major vulnerability – but relatively little systematic evaluation exists on the topic. Likewise, ICT infrastructure is vulnerable to natural disasters too – and the risk of more severe natural disasters in the context of a global trend toward massive cities is increasing dramatically. Explicit consideration of the issues associated with cross-domain integration of reduction of interdependent risk is a necessary step in ensuring smart city technologies also serve to promote longer-term community sustainability and resilience.

IoT Security and Safety Testing Toolkits for Water Distribution Systems
Due to the critical importance of Industrial Control Systems (ICS) to the operations of cities and countries, research into the security of critical infrastructure has become increasingly relevant and necessary. As a component of both the research and application sides of smart city development, accurate and precise modeling, simulation, and verification are key parts of a robust design and development tools that provide critical assistance in the prevention, detection, and recovery from abnormal behavior in the sensors, controllers, and actuators which make up a modern ICS system. However, while these tools have potential, there is currently a need for helper-tools to assist with their setup and configuration, if they are to be utilized widely. Existing state-of-the-art tools are often technically complex and difficult to customize for any given IoT/ICS processes. This is a serious barrier to entry for most technicians, engineers, researchers, and smart city planners, while slowing down the critical aspects of safety and security verification. To remedy this issue, we take a case study of existing simulation toolkits within the field of water management and expand on existing tools and algorithms with simplistic automated retrieval functionality using a much more in-depth and usable customization interface to accelerate simulation scenario design and implementation, allowing for customization of the cyber-physical network infrastructure and cyber attack scenarios. We additionally provide a novel in tool assessment of network’s resilience according to graph theory path diversity. Further, we lay out a roadmap for future development and application of the proposed tool, including expansions on resiliency and potential vulnerability model checking, and discuss applications of our work to other fields relevant to the design and operation of smart cities.

In recent years, there has been a growing interest in so-called smart cities. These cities use technology to connect and enhance the lives of their citizens. Smart cities use many Internet of Things (loT) devices, such as sensors and video cameras, that are interconnected to provide constant feedback and up-to-date information on everything that is happening. Despite the benefits of these cities, they introduce a numerous new vulnerabilities as well. These smart cities are now susceptible to cyber-attacks that aim to “alter, disrupt, deceive, degrade, or destroy computer systems.” Through the use of an educational and research-based loT test-bed with multiple networking layers and heterogeneous devices connected to simultaneously support networking research, anomaly detection, and security principles, we can pinpoint some of these vulnerabilities. This work will contribute potential solutions to these vulnerabilities that can hopefully be replicated in smart cities around the world. Specifically, in the transportation section of our educational smart city several vulnerabilities in the signal lights, street lights, and the cities train network were discovered. To conduct this research two scenarios were developed. These consisted of inside the network security and network perimeter security. For the latter we were able to find extensive vulnerabilities that would allow an attacker to map the entire smart city sub-network. Solutions to this problem are outlined that utilize an Intrusion Detection System and Port Mirroring. However, while we were able to exploit the city's Programmable Logic Controller (PLC) once inside the network, it was found that due to dated Supervisory Control and Data Acquisition (SCADA) systems, there were almost no solutions to these exploits.more » « less

The technological advancements along with the proliferation of smart and connected devices (things) motivated the exploration of the creation of smart cities aimed at improving the quality of life, economic growth, and efficient resource utilization. Some recent initiatives defined a smart city network as the interconnection of the existing independent and heterogeneous networks and the infrastructure. However, considering the heterogeneity of the devices, communication technologies, network protocols, and platforms the interoperability of these networks is a challenge requiring more attention. In this paper, we propose the design of a novel Information-Centric Smart City architecture (iSmart), focusing on the demand of the future applications, such as efficient machine-to-machine communication, low latency computation offloading, large data communication requirements, andadvanced security. In designing iSmart, we use the Named-Data Networking (NDN) architecture as the underlyingcommunication substrate to promote semantics-based communication and achieve seamless compute/data sharing.more » « less

Industrial Control Systems (ICS) are the brain and backbone of nation's critical infrastructure such as nuclear power, water treatment, and petrochemical plants. In order to increase interoperability, real-time availability of data, and flexibility, information/communication technologies are adopted in this domain. While these information technologies have been effective, they are integrated into operational technologies without the necessary security defense. Designing an effective, layered security defense is not possible unless security threats are identified through a structural analysis of the ICS. For that reason, this paper provides an attacker's point of view on the reconnaissance effort necessary to gather details of the system dynamics - which are required for the development of sophisticated attacks. We present a reconnaissance approach which uses the system's I/O data to infer the dynamic model of the system. In this effort, we propose a novel cyber-attack which targets the controller proportional-integral-derivative gain values in a constant setpoint control system. Our findings will help researchers design more secure control systems.more » « less
