From Risk Analysis to the Expression of Security Requirements for Systems Information

Several methods have been suggested to address the identification of security requirements for information systems (IS) from risk analysis or not. To the best of our knowledge, there is no methodology that enables the derivation in a formal way of security requirements starting from risk analysis. The aim of this paper is to provide a guiding method allowing us to determine security requirements based on risk analysis. To achieve this objective, we propose to align the concepts of assets, risks to those of security requirements through the use of three ontologies: assets, risks and security requirements. The alignment of the three ontologies is based on best practices in the security domain. In addition to the description of guiding method, we detail, in this paper, the approaches used for the construction and alignment of the three ontologies.
