Cybersecurity investments : decision support under economic aspects
This book offers readers essential orientation on cybersecurity safeguards, and first and foremost helps them find the right balance between financial expenditures and risk mitigation. This is achieved by pursuing a multi-disciplinary approach that combines well-founded methods from economics and the computer sciences. Established decision making techniques are embedded into a walk-through for the complete lifecycle of cybersecurity investments. Insights into the economic aspect of the costs and benefits of cybersecurity are supplemented by established and innovative economic indicators. Readers will find practical tools and techniques to support reasonable decision making in cybersecurity investments. Further, they will be equipped to encourage a common understanding using economic aspects, and to provide cost transparency for the senior management.

Cybersecurity in Humanities and Social Sciences
The humanities and social sciences are interested in the cybersecurity object since its emergence in the security debates, at the beginning of the 2000s. This scientific production is thus still relatively young, but diversified, mobilizing at the same time political science, international relations, sociology, law, information science, security studies, surveillance studies, strategic studies, polemology. There is, however, no actual cybersecurity studies. After two decades of scientific production on this subject, we thought it essential to take stock of the research methods that could be mobilized, imagined and invented by the researchers. The research methodology on the subject \"cybersecurity\" has, paradoxically, been the subject of relatively few publications to date. This dimension is essential. It is the initial phase by which any researcher, seasoned or young doctoral student, must pass, to define his subject of study, delimit the contours, ask the research questions, and choose the methods of treatment. It is this methodological dimension that our book proposes to treat. The questions the authors were asked to answer were: how can cybersecurity be defined? What disciplines in the humanities and social sciences are studying, and how, cybersecurity? What is the place of pluralism or interdisciplinarity? How are the research topics chosen, the questions defined? How, concretely, to study cybersecurity: tools, methods, theories, organization of research, research fields, data...? How are discipline-specific theories useful for understanding and studying cybersecurity? Has cybersecurity had an impact on scientific theories?

Foundational Cybersecurity Research
Attaining meaningful cybersecurity presents a broad societal challenge. Its complexity and the range of systems and sectors in which it is needed mean that successful approaches are necessarily multifaceted. Moreover, cybersecurity is a dynamic process involving human attackers who continue to adapt. Despite considerable investments of resources and intellect, cybersecurity continues to poses serious challenges to national security, business performance, and public well-being. Modern developments in computation, storage and connectivity to the Internet have brought into even sharper focus the need for a better understanding of the overall security of the systems we depend on.
Foundational Cybersecurity Research focuses on foundational research strategies for organizing people, technologies, and governance. These strategies seek to ensure the sustained support needed to create an agile, effective research community, with collaborative links across disciplines and between research and practice. This report is aimed primarily at the cybersecurity research community, but takes a broad view that efforts to improve foundational cybersecurity research will need to include many disciplines working together to achieve common goals.

Perspectives on Cybersecurity
The book Perspectives on Cybersecurity offers a broad look at the very actual yet still understudied area of cybersecurity. Individual chapters provide insights into crucial issues such as cyber warfare, espionage, specific legal and economic aspects, international cooperation, and social construction of cyberspace. It covers a number of topics and approaches which are needed to understand and appreciate the intricacies of cybersecurity.

Information security research classification for future multimedia environment
In spite of the advancement of information security (IS) technology, information leakage incidents and accidents are continuously occurring. Its reason is because only technical countermeasures are devised rather than implementing countermeasures based on business perspective regarding IS. Accordingly, the purpose of this study is to design a classification system in the area of IS to solve such problem and seek balanced advancement, as well as examine the trend of IS researches that have been conducted. Upon designing the classification system based on the areas of IS technology and IS management for the IS academic areas, Korea domestic and international academic journals in the area of IS were selected to research and analyze theses that have been published in the last 5 years. The research result showed that there were more studies on IS technology area than IS management area, thereby confirming the greater research emphasis in the area of technology. In specific according to area, number of Korea domestic researches on infrastructure security technology was the highest in the area of IS technology. In the case of international researches, number of researches on the security of infrastructure was the highest. As for the IS management area, number of Korea domestic researches on IS level diagnosis was the highest, while number international researches on IS human resource management was the highest. The significance of this study is to contribute to the balanced advancement of IS area by designing IS classification system to present IS research trend and future research direction.

Research on the Security of NC-Link Numerical Control Equipment Protocol Based on Colored Petri Net
The NC-Link protocol, as an integrated communication protocol in the Computerized Numerical Control (CNC) machine tool industry, has drawn significant attention regarding its security since its inception. Although there have been studies proposing improvements to address security issues related to key management and message transmission, systematic security analysis of the protocol remains relatively weak. To better investigate and enhance the security of the NC-Link protocol, our research introduces a formal modeling and analysis method based on Colored Petri Nets (CPN). By establishing a CPN model of the protocol, we analyze the security issues present during communication and propose improvement measures for verification and analysis. First, we developed a CPN model for the NC-Link protocol and verified the model’s feasibility through simulation analysis. Subsequently, we introduced an attacker model to analyze the protocol’s authentication interaction process, revealing security issues, such as authentication vulnerabilities and key management flaws. Finally, we proposed an improved scheme addressing these issues and conducted a security validation and cost analysis of this scheme. The results show that the improved protocol reduces the computational overhead by 75% during the connection and interaction phases. This indicates that the improved protocol can achieve interactions at a faster speed while maintaining higher security and reliability. The implementation of this scheme provides new reference ideas for related research.
