Nowadays, it has become increasingly important for companies to effectively manage cybersecurity risks in emerging technologies. This article presents an overview of cybersecurity in these technologies. It sheds light on the obstacles that businesses encounter when dealing with these risks. The field of cybersecurity poses challenges that need to be overcome. Technical challenges include securing communication networks and protecting data and systems from threats. Moreover, it is crucial to ensure the dependability and trustworthiness of emerging technologies. Organisational challenges involve preparing and training employees and devising effective strategies to address the unique cybersecurity issues associated with new technologies. Regulatory challenges arise due to changing compliance requirements in a global context where different countries have diverse cybersecurity laws. To effectively manage cybersecurity risks, it is essential to follow established risk management practices, such as identifying and assessing risks systematically. However, there are gaps in research and practices that should be addressed. These gaps include the lack of frameworks for conducting cost-benefit analyses, a limited understanding of the role played by error in cybersecurity incidents, and the necessity for comprehensive strategies to deal with the constantly evolving landscape of cybersecurity threats. Bridging these gaps requires investigation along with developing effective strategies for improving cybersecurity in emerging technologies.

“…The results show that the more homogeneous the structure, the higher the reliability and high robustness of the grid and the lower the vulnerability. In order to integrate the non-uniformity of the system structure and state, [47][48] proposed the use of entropy theory to improve the metrics, integrating the equilibrium of the system and the fluctuation of the tidal currents. To solve the lack of comprehensive evaluation method, [49] used VIKOR comprehensive evaluation method to get the node importance ranking.…”

The increasing scale of wind power access to the grid makes it important to identify weak links in the system to prevent major outages. In order to analyze the vulnerability of grid nodes, this paper proposes a dynamic comprehensive evaluation method considering system uniformity, and establishes a comprehensive assessment model of node vulnerability based on wind power grid-connectedness, based on which the vulnerability of wind power-containing power systems is studied. Firstly, the improved weighted power entropy index is selected for the phenomena of system current instability and line overloading, and the comprehensive index set of node vulnerability is constructed by considering the structural and state characteristics, and the subjective and objective weights are calculated by using the hierarchical analysis method and the CRITIC method. Subsequently, the Dagum-Gini coefficient method is utilized to reflect the homogeneity of the system, and a comprehensive evaluation method based on the VIKOR method is used to confirm the ordering of critical nodes that have the greatest impact on the system and have a high failure rate. Finally, the proposed method is applied to the study of node vulnerability of wind-containing power systems. The feasibility of the above methodology is verified by a modified IEEE-118 test system with test simulations.
