Cybersecurity risk assessment for Unmanned Aircraft Systems
Évaluation des risque de cybersecurité pour les systèmes de drones
Résumé
Nowadays, the increasing number of Unmanned Aircraft System (UAS) operations raises public concerns on cybersecurity issues. Therefore, it requires methodologies to address these issues during the UAS development. It is the focal point of our research. This thesis has two significant contributions. Firstly, we propose a system-centric methodology to reinforce the cybersecurity of an existing (or designed) UAS. This methodology provides the user with a workflow to analyze the UAS, identify the possible attack scenarios, and identify suitable countermeasures. We call this methodology “System cybersecurity risk management”. Secondly, we propose an operation-centric methodology that considers the cybersecurity issues in the early phase of the UAS development (before the UAS is designed). This methodology is an extended version of the Specific Operation Risk assessment methodology (SORA). The SORA is a wide-known methodology to assess the risks of UAS operations under the “Specific” category. However, the current stage of the SORA methodology focuses only on safety but ignore cybersecurity. Our extension modules fulfill this missing part. We call our extension methodology as Specific Operation Risk assessment for Safety and Cybersecurity (SORA-C2S). Based on this methodology, we built a web-based tool that helps the user to perform the risk assessment semi-automatically. This thesis is a part of the cooperation between the SOGILIS Company and the GIPSA lab.
