This thesis presents a behavioral economics contribution to the security of information systems. It focuses on security information sharing (SIS) between operators of critical infrastructures, such as systemic banks, power grids, or telecommunications. SIS is an activity by which these operators exchange cybersecurity-relevant information, for instance on vulnerabilities, malwares, data breaches, etc. Such information sharing is a low-cost and efficient way by which the defenders of such infrastructures can enhance cybersecurity. However, despite this advantage, economic (dis)incentives, such as the free-rider problem, often reduce the extent to which SIS is actually used in practice. This thesis responds to this problem with three published articles. The first article sets out a theoretical framework that proposes an association between human behavior and SIS outcomes. The second article further develops and empirically tests this proposed association, using data from a self-developed psychometric survey among all participants of the Swiss Reporting and Analysis Centre for Information Assurance (MELANI). SIS is measured by a dual approach (intensity and frequency), and hypotheses on five salient factors that are likely associated with SIS outcomes (attitude, reciprocity, executional cost, reputation, trust) are tested. In the third article, policy recommendations are presented in order to reduce executional costs, which is found to be significantly and negatively associated with SIS. In conclusion, this thesis proposes multiple scientific and practical contributions. It extends the scientific literature on the economics of cybersecurity with three contributions on the human factor in SIS. In addition, regulators will find many recommendations, particularly in the area of governance, to support SIS at the legislative level. This thesis also offers many avenues for practitioners to improve the efficiency of SIS, particularly within Information Sharing and Analysis Centers (ISACs) in charge of producing Cyber ...

This open access book reports the results of a study conducted in Switzerland in 2022 to provide an overview of the changing landscape of encryption and data protection technologies and their global usage trends. The Swiss Confederation tasked the Cyber-Defence Campus (CYD Campus) to identify the 38 most relevant encryption and data protection technologies, analyze their expected evolution until 2025, and derive implications for the military, civil society, and economy sectors. Fifty experts from academia, government, and industry have contributed to this study and provided their viewpoints on the different technologies and trends. This comprehensive collection of factsheets provides a reference for organizations and individuals that need to elaborate coherent and efficient data protection and encryption strategies in the coming years. The 38 technologies have been sorted into five categories. First, encryption foundations represent the technologies used to create other encryption applications. Second, low-level applications represent the technologies that focus on micro functionalities. Third, high-level applications represent the technologies that focus on more abstract and macro functionalities. Fourth, data protection represents the technologies used to protect data without encrypting these data. Finally, use cases represent concrete ways the different technologies can be used together to create a working solution. The book serves as a guide for decision-making within administrations, government organizations, and industry. It will also be interesting for the tech-savvy board member or engineers looking to get an entry point into data protection topics. Last not least, the book will also be a valuable reading for anyone interested in data protection and encryption.
