“…Our analysis revealed that in the last decade, CPSs have emerged as a new paradigm and as a result of the increased growth, complexity and heterogeneity of these infrastructures [14,82], the volume and the variety of vulnerabilities and attacks have evolved highlighting the need for defence mechanisms [147], need for cyber resilience and capability to support DFIR [26,29,30,33]. In this paper, the analysis of the primary studies supports our assertion that CPS-related cyber resilience and DFIR are active research domains.…”

“…The rise of cybercrime has been greatly facilitated by the proliferation of modern advanced electronic communication technologies and the integration of IoT with physical systems [17,28,33]. High profile cyberattacks on ICSs have been well reported for some years, such as the Stuxnet malware targeting the Iranian nuclear plant [34], the attack on the Ukrainian power grid [35] or Norsk Hydro, a renewable energy supplier and the world's largest aluminium producer, which was compromised by the LockerGoga ransomware [32].…”

Cyber Resilience and Incident Response in Smart Cities: A Systematic Literature Review

The world is experiencing a rapid growth of smart cities accelerated by Industry 4.0, including the Internet of Things (IoT), and enhanced by the application of emerging innovative technologies which in turn create highly fragile and complex cyber–physical–natural ecosystems. This paper systematically identifies peer-reviewed literature and explicitly investigates empirical primary studies that address cyber resilience and digital forensic incident response (DFIR) aspects of cyber–physical systems (CPSs) in smart cities. Our findings show that CPSs addressing cyber resilience and support for modern DFIR are a recent paradigm. Most of the primary studies are focused on a subset of the incident response process, the “detection and analysis” phase whilst attempts to address other parts of the DFIR process remain limited. Further analysis shows that research focused on smart healthcare and smart citizen were addressed only by a small number of primary studies. Additionally, our findings identify a lack of available real CPS-generated datasets limiting the experiments to mostly testbed type environments or in some cases authors relied on simulation software. Therefore, contributing this systematic literature review (SLR), we used a search protocol providing an evidence-based summary of the key themes and main focus domains investigating cyber resilience and DFIR addressed by CPS frameworks and systems. This SLR also provides scientific evidence of the gaps in the literature for possible future directions for research within the CPS cybersecurity realm. In total, 600 papers were surveyed from which 52 primary studies were included and analysed.

“…Accordingly, significant efforts have been made to develop appropriate models to map out the interdependencies of complex systems. Even though several researchers attempted to model dependencies between all the critical infrastructures [ 28 , 29 , 30 ], the majority focused on limited numbers of critical infrastructures [ 31 , 32 ], particularly on the power and ICT infrastructures [ 33 , 34 ].…”

“…An empirical study on different CIs showed that energy and telecommunications are the main cascading-initiating sectors [ 23 ]. As a result, significant efforts have been made in the last few years to study and model the interdependencies of power systems combined with ICT systems, viewed as complex cyber-physical systems, to improve defensive and protective strategies in the cyber and physical layers of power systems [ 33 , 34 , 35 , 36 , 37 ].…”

Contemporary Critical Infrastructures (CIs), such as the power grid, comprise cyber physical systems that are tightly coupled, to form a complex system of interconnected components with interacting dependencies. Modelling methodologies have been suggested as proper tools to provide better insight into the dependencies and behavioural characteristics of these complex systems. In order to facilitate the study of interconnections in and among critical infrastructures, and to provide a clear view of the interdependencies among their cyber and physical components, this paper proposes a novel method, based on a graphical model called Modified Dependency Structure Matrix (MDSM). The MDSM provides a compact perspective of both inter-dependency and intra-dependency between subsystems of one complex system or two distinct systems. Additionally, we propose four parameters that allow the quantitative assessment of the characteristics of dependencies, including multi-order dependencies in large scale CIs. We illustrate the workings of the proposed method by applying it to a micro-distribution network based on the G2ELAB 14-Bus model. The results provide valuable insight into the dependencies among the network components and substantiate the applicability of the proposed method for analyzing large scale cyber physical systems.

A resilient optimal energy scheduling in interconnected smart buildings considering cyber-attack detection has been proposed in the present work. The proposed resilient scheduling considers interconnected multiple smart buildings with power exchange capability among the smart buildings. It is considered that each smart building is equipped with different types of distributed energy resources, battery storage systems, combined heat and power generators, thermal storage systems, and smart appliances. A comprehensive optimal and robust scheduling is formulated considering false data injection attack.The proposed method uses the information of anomaly between the actual and forecasted bills for detecting the cyber attack and making a resilient scheduling against possible attacks. The studies indicate that the optimal scheduling in interconnected smart buildings may reduce the cost up to 4.53% for the system depending on number of interconnected smart buildings.energy management system, FDIA, FDIA detection, power exchange capability, real time pricing | INTRODUCTIONSmart home are end-users of power grids, and they are essential components of the smart grid infrastructure. Smart home appliance scheduling techniques play a significant role in smart home energy management systems (SHEMS) as they are responsible for energy consumption. Multi-smart building energy management systems (MSBEMS) are specifically used to reduce dependency on the main utility because they can trade power among themselves. In this way, the consumer's average energy cost is reduced, and the energy load balance of the power grid is maintained for a fixed time horizon. A welldesigned electricity pricing scheme from the utility side will guide the energy consumption of the MSBEMS consumer. The utility also provides its consumer with a demand response (DR) program for proper energy usage at different time intervals. Renewable energy resources (RERs) such as roof-top wind turbine and solar PV panels are installed in residential smart buildings to reduce
