Collection of Quantitative Data on Security Incidents

Quantitative data about security threats is a precondition for a precise assessment of security risks and consequently for an efficient management of information security.

We identify basic requirements for such a platform and show approaches for satisfying them. We especially emphasize the aspects of security and fairness. Finally we introduce a prototype that shows how an implementation could look like
