Multi-objective decision support for IT security control selection

Identifying an optimal sets of security controls to protect complex information
systems is a challenging problem. The aim of the research project MOSES3 is to develop and implement a framework that supports decision-makers in this task. Our approach rests upon comprehensive modeling of security knowledge, dynamic attack tree generation techniques, discrete event simulation of sophisticated attacks that exploit emergent weaknesses, and multi-objective optimization of security
control portfolios. In our talk we outline the overall framework and present preliminary results.
