The goal of this master thesis is the research on available data sources for corporate security and the foundation to enable data usage as a self-service. Therefore it introduces the self-service tool Midas, which enabled the end user of data to also work with data. The analyzed data sets of GDELT and UCDP focus on data of critical events in a retrospective and a real-time view and give a good perspective on the bigger picture for situation analysis. But especially for the data provided by GDELT the analysis has shown the need for additional processing due to little prefiltering. This is extended by the media monitoring to collect data on real-time events. This isn't as intuitive as expected and relies heavily on the social media communication of trusted sources like the polices to ensure a level of reliability. Those results were compared to another event data provider but didn't show a high number of matches. The thesis also proposes an ontology for events relevant to corporate security based on the available data from the previous analysis. It is an introduction for data analysts and people involved in ensuring corporate security.
