There is widespread agreement that critical infrastructure security and resilience must be enhanced. In the UK, sector security and resilience plans provide the strategic vision to guide the national effort to manage risk to the Critical National Infrastructures (CNI) [1]. Nevertheless, the complexity of CNIs and their inherent interdependencies make it difficult to realise this aim. Therefore, research efforts are devoted to developing new methodologies for understanding and consequently, managing the risks associated with interconnected CNIs.

Harnessing multiple urban smart systems to create resilient cities has been a primary objective in making smart cities more robust and efficient. Since a smart city can be advocated as a system of systems, many solutions have tried to exploit different types of data to optimize available resources when pursuing higher levels of resilience. However, smart city solutions have been mostly confined to a particular scope of operation with a well-known limited set of parameters, often due to technological constraints and limited availability of relevant data.

Critical infrastructures of smart cities, such as those that support emergency services and power delivery, should be properly maintained to minimize the risk of failure. Analytical utilization of operational data gathered from various sources and sensing networks are stored by computerized maintenance management systems (CMMSs). When properly implemented, CMMS will drastically improve performance of maintenance efficiency. Data-driven maintenance management of smart cities’ critical infrastructures is thus introduced in this paper with the primary objective of making critical infrastructures more reliable. This paper also provides a demonstrative case study of an energy distribution system's maintenance management scheduling project to illustrate the implementation of CMMS.

With the increasing digitization of smart grids, especially urban civil power infrastructures, new opportunities for grid operation but also potential threats emerge that endanger the power supply. In order to investigate the cyber-physical resilience of new use cases, a co-simulation environment is developed that allows a detailed simulation of multiple domains of interest. In particular, flexibility coordination of distributed energy resources in combination with threat analysis of cyberattacks provides the first foundations for a holistic investigation environment for cyber-physical resilience.

As cities become more intelligent, the demand for centralized intelligence and control centres increases. There are numerous definitions of Smart City. As mentioned by IEEE Smart Cities: Smart Energy, Smart Economy, Smart Mobility, Smart Environment, Smart Governance, and Smart Living are the key domains that enable citizens to utilize interconnected infrastructure to improve the quality of life for urban residents.
