Risk assessment and security testing of large scale networked systems with RACOMAT

Risk management is an important part of the software quality management because security issues can result in big economical losses and even worse legal consequences. While risk assessment as the base for any risk treatment is widely regarded to be important, doing a risk assessment itself remains a challenge especially for complex large scaled networked systems. This paper presents an ongoing case study in which such a system is assessed. In order to deal with the challenges from that case study, the RACOMAT method and the RACOMAT tool for compositional risk assessment closely combined with security testing and incident simulation for have been developed with the goal to reach a new level of automation results in risk assessment
