Vers une ingénierie avancée de la sécurité des systèmes d'information d'entreprise : une approche conjointe de la sécurité, de l'utilisabilité et de la résilience dans les systèmes sociotechniques

Abstract : In our era of the service industry, information systems play a prominent role. They even hold a vital position for businesses, organizations and individuals. Information systems are confronted with new security threats on an ongoing basis; these threats become more and more sophisticated and of different natures. In this context, it is important to prevent attackers from achieving their results, to manage the inevitable flaws, and to minimize their impacts. Security practices must be carried out within an engineering framework; Security engineering needs to be improved. To do this, it is proposed to develop systemic approaches, innovative on wide spectra and that work on several axes together, improving the user experience. Our goal is to jointly track down and resolve issues of security, usability and resiliency in enterprise information systems. In this doctoral thesis, we position sociotechnical systems in relation to the information systems of companies and organizations. We address paradigms of sociotechnical systems and refocus on the correlations between security, usability and resilience. A case study illustrates the proposed approach. It presents the development of design patterns to improve the user experience. The thesis concludes with an overall discussion of the approach, as well as research perspectives.
