Information exchange has become increasingly faster and efficient through the use of recent technological advances, such as instant messaging and social media platforms. Consequently, access to information has become easier. However, new types of cybersecurity threats that typically result in data loss and information misuse have emerged simultaneously. Therefore, maintaining data privacy in complex systems is important and necessary, particularly in organizations where the vast majority of individuals interacting with these systems is students. In most cases, students engage in data breaches and digital misconduct due to the lack of knowledge and awareness of cybersecurity and the consequences of cybercrime. The aim of this study was to investigate and evaluate the level of cybersecurity awareness and user compliance among undergraduate students at Majmaah University using a scientific questionnaire based on several safety factors for the use of the Internet. We quantitatively evaluated the knowledge of cybercrime and protection among students to show the need for user education, training, and awareness. In this study, we used a quantitative research methodology and conducted different statistical tests, such as ANOVA, Kaiser–Meyer–Olkin (KMO), and Bartlett’s tests, to evaluate and analyze the hypotheses. Safety concerns for electronic emails, computer viruses, phishing, forged ads, popup windows, and supplementary outbreaks on the Internet were well-examined in this study. Finally, we present recommendations based on the collected data to deal with this common problem.

With the exponential increase in the complexity of network management and configuration, Software Defined Networking (SDN) has emerged as a promising network paradigm. SDN aims to efficiently transform network architecture and operations to be agile, and effectively enrich the functionality of underlying network elements, such as routers and switches, by decoupling the control plane from the data plane. In SDN, the network intelligence is centralized in a software entity so-called SDN controller, which enables network administrators to dynamically manage, secure, and optimize network resources and programmatically shape all entire network traffic pattern. Despite the impressive benefits SDN has brought to network architecture, it introduces new security challenges and prompts different implementation strategies to spread attack vectors. This paper comprehensively describes the utilization of Blockchain technology to secure and protect SDN architecture and discusses the feasibility of integrating the revolutionary technologies of SDN and Blockchain to provide confidentiality, integrity, and availability to network infrastructure.

Increasing the proportion of renewable energy generations in remote island power systems is becoming essential for realizing decarbonized society. However, since inverter-connected renewable energies have different generation characteristics from conventional generators, the massive penetration can adversely affect system stability. In particular, fault events in such weak remote systems can cause fast voltage collapse, and there is a need to assess dynamic voltage stability. This study attempts dynamic voltage stability assessment using the critical boundary index (CBI) and investigates the impact of the virtual synchronous generator (VSG) on dynamic voltage stability. A remote island power system and VSG are modeled, and time-domain simulations are conducted with case studies of fault events. The simulation results show the potential of CBI to use for dynamic voltage stability assessment. Furthermore, the VSG can provide suitable power output during fault events and improve dynamic voltage stability.

The evolution of information systems has escalated significantly within the last decade as research unveils new concepts. The general orientation to provide solutions to complex problems continues to inspire innovation and new advancements. Cybersecurity is emerging as a critical factor for consideration within the resultant paradigm as information systems become significantly integrated. This paper provides an in-depth analysis of cybersecurity within the context of information systems. The paper examines some of the most consequential aspects of cybersecurity from the perspective of an e-government project in Saudi Arabia. A holistic system is proposed within the research framework to incorporate various scientific guidelines. The general orientation of this research is predicated on the aspiration to design and implement a complex and robust framework within which an e-government system can thrive within the Saudi Arabian context. A consideration of the physical environment within which the project will operate is also made, focusing on security. An evaluation of the cybersecurity environment in Saudi Arabia is reflective of significant advancements that have occurred in information system domains within the past few years.

Software Defined Networking (SDN) is a new networking paradigm with the promise to increase simplicity and efficiency in network management through the separation of control functions from the forwarding functions. In SDN, the control functions are softwarized and logically placed in a centralized entity, i.e. the SDN controller. Network virtualization is one of the key features enabled and facilitated by the SDN, and it allows multiple virtual networks and the SDN controllers to share the same physical network infrastructure. This paper discusses the security of virtualization in the SDN, and it highlights and demonstrates critical vulnerabilities of key network hypervisors used in the SDN. In particular, the paper demonstrates how the isolation of different virtual networks can be broken, and enabling different types of attacks. Finally, the paper discusses the potential impact of these vulnerabilities and points to mitigation approaches.
