The main objective of MASSIF is to achieve a significant advance in the area of Security Information and Event Management (SIEM). On the base of proper multi-level event correlation MASSIF will provide innovation techniques in order to enable the detection of upcoming security threats and trigger remediation actions even before the occurrence of possible security incidences. Thus, MASSIF will develop a new generation SIEM framework for service infrastructures supporting intelligent, scalable, and multi-level/multi-domain security event processing and predictive security monitoring.Such service-level SIEM involves the modelling and formal validation of security, including trusted computing concepts (Fraunhofer), architecture for dependable and resilient collection of service events (Uni. Lisboa), supported by an extremely scalable and performant event collection and processing framework (UPM), in the context of service-level attack models (SPIIRAS).Four industrial domains serve as a source for requirementsand to validate and demonstrate project results: (i) Olympic Games IT infrastructure deployed and managed by Atos Origin; (ii) France Telecom scenario on "Mobile phone based money transfer service" facing security events, especially for the "non-IT" and "service" events; (iii) T-Systems South Africa provides managed IT outsource services with a high degree of complexity in setting up SIEM systems for large distributed enterprises; and (iv) Epsilon (an SME) will demonstrate the use of the advanced concepts of SIEM in an IT system supporting a critical infrastructure (dam).Deep insight into the current and near future industrial state-of-art is provided by (1) AlienVault, as the creator and maintainer of the leading open source SIEM product (OSSIM), (2) Integration of MASSIF results into Prelude (second largest open source SIEM product) by Institut Telecom, and (3) Use and Deployment of huge installations of commercial SIEM products.
