Enhancing Maritime Cybersecurity through Operational Technology Sensor Data Fusion: A Comprehensive Survey and Analysis

Cybersecurity is becoming an increasingly important aspect in ensuring maritime data protection and operational continuity. Ships, ports, surveillance and navigation systems, industrial technology, cargo, and logistics systems all contribute to a complex maritime environment with a significant cyberattack surface. To that aim, a wide range of cyberattacks in the maritime domain are possible, with the potential to infect vulnerable information and communication systems, compromising safety and security. The use of navigation and surveillance systems, which are considered as part of the maritime OT sensors, can improve maritime cyber situational awareness. This survey critically investigates whether the fusion of OT data, which are used to provide maritime situational awareness, may also improve the ability to detect cyberincidents in real time or near-real time. It includes a thorough analysis of the relevant literature, emphasizing RF but also other sensors, and data fusion approaches that can help improve maritime cybersecurity.

Highlighting Effects of Flipped Learning on Mental Health through Metaverse: Moderating Impact of e-learning and Cyber Resilience

Objectives: A metaverse refers to a virtual-reality platform in which users can interact with computer- generated environment, to socialize. It has really enhanced the internet-based and online education. The current study aimed to evaluate the effect of flipped learning on mental health through metaverse. There is a huge potential for expanding learning and knowledge through metaverse, and educational institutions worldwide are evolving to incorporate this concept. To explore the effects of flipped learning on mental health through the metaverse, the study examined the moderating influence of e-learning and cyber resilience by adopting interactive methods in the context of China. Methods: The study employed a quantitative design by conducting surveys from students in Chinese educational institutions. A sample of 350 questionnaires was distributed among the students, out of which 324 complete questionnaires were obtained for further analysis. Results: The findings showed a significant effect of flipped learning on mental health through metaverse. It also exposed the significance of the moderating effect of cyber resilience. In contrast, the moderating effect of e-learning was found to be insignificant between flipped learning through metaverse and students' mental health in Chinese educational institutions. Conclusion: The study provides insightful and practical guidelines for China's education and cybersecurity departments.

Why Resilience in Health Care Systems is More than Coping with Disasters: Implications for Health Care Policy

Health care systems need to be resilient to deal with disasters like the global spread of the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) on top of serving the changing needs of a multi-morbid, ageing and often dispersed population. This paper identifies, discusses and augments critical dimensions of resilience retrieved from the academic literature. It pulls together an integrated concept of resilience characterised by organisational capabilities. Our concept does not focus on the micro-level like most resilience literature in health care but addresses the system level with many stakeholders involved. Distinguishing exogenous shocks to the health care system into adverse events and planned innovations provides the basis for our conclusions and insights. It becomes apparent only when dealing with planned interventions that transformative capabilities are indispensable to cope with sudden increases in health care pressures. Due to the current focus on absorptive and adaptive resilience, organisations over-rely on management capabilities that cannot generate a lasting increase in functionality. Therefore, reducing the resilience discussion to bouncing back from adverse events could deceive organisations into cultivating a suboptimal mix of organisational capabilities lacking transformative capabilities, which pave the way for a structural change that aims at a sustainably higher functionality.

Resilience Assessment Frameworks of Critical Infrastructures: State-of-the-Art Review

During the past two decades, critical infrastructures (CIs) faced a growing number of challenges worldwide due to natural disasters and other disruptive events. To respond to and handle these disasters and disruptive events, the concept of resilience was introduced to CIs. Particularly, many institutions and scholars developed various types of frameworks to assess and enhance CI resilience. The purpose of this paper is to review the resilience assessment frameworks of the CIs proposed by quality papers published in the past decade, determine and analyze the common dimensions and the key indicators of resilience assessment frameworks of CIs, and propose possible opportunities for future research. To achieve these goals, a comprehensive literature review was conducted, which identified 24 resilience assessment frameworks from 24 quality papers. This paper contributes to the current body of resilience research by identifying the common dimensions and the key indicators of the resilience assessment frameworks proposed for CIs. In addition, this paper is beneficial to the practice, because it provides a comprehensive view of the resilience assessment frameworks of CIs from the perspective of implementation, and the indicators are pragmatic and actionable in practice.

Cyber Resilience Progression Model

Due to the hazardous current cyber environment, cyber resilience is more necessary than ever. Companies are exposed to an often-ignored risk of suffering a cyber incident. This places cyber incidents as one of the main risks for companies in the past few years. On the other hand, the literature meant to aid on the operationalization of cyber resilience is mostly focused on listing the policies required to operationalize it, but is often lacking on how to prioritize these actions and how to strategize their implementation. Therefore, the usage of the current literature in this state is not optimal for companies. Thus, this study proposes a progression model to help companies strategize and prioritize cyber resilience policies by proposing the natural evolution of the policies over time. To develop the model, this study used semi-structured interviews and an analysis of the data obtained from the interviews. Through this methodology, this study found the starting points for each cyber resilience policy and their natural progression over time. These results can help companies in their cyber resilience building process by giving them insights on how to strategize the implementation of the cyber resilience policies.
