To this end, data leakage solutions are usually employed by organizations to monitor network traffic and the use of portable storage devices. These solutions often produce a large number of alerts, whose analysis is time-consuming and costly for organizations. To effectively handle leakage incidents, organizations should be able to focus on the most severe incidents. Therefore, alerts need to be prioritized with respect to their severity. This work presents a novel approach for the quantification of data leakages based on their severity. The approach quantifies leakages with respect to the amount and sensitivity of the leaked information as well as the ability to identify the data subjects of the leaked information. To specify and reason on data sensitivity in an application domain, we propose a data model representing the knowledge in the domain. We validate our approach by analyzing data leakages within a healthcare environment. %G English %Z TC 11 %Z WG 11.3 %2 https://inria.hal.science/hal-01284845/document %2 https://inria.hal.science/hal-01284845/file/978-3-662-43936-4_7_Chapter.pdf %L hal-01284845 %U https://inria.hal.science/hal-01284845 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC11 %~ IFIP-LNCS-8566 %~ IFIP-WG11-3
