Abstract
Nowadays, Olympic Games have become one of the most profitable global media events, becoming at the same way more and more attractive target from the terrorist perspective due to their media diffusion and international dimension. Critical for the success of such a highly visible event is protecting and securing the business and the supporting cyber infrastructure enabling it. In this context, the MASSIF project aims to provide a new generation SIEM framework for service infrastructures supporting intelligent, scalable, and multi-level/multi-domain security event processing and predictive security monitoring.
