Executive Summary

At present, an analysis based on the threat tree is used for analysis of threats to information systems. Orientation to a single threat is a characteristic feature of this method. If the analysis is more extensive, then a threat tree is created for each single threat. This solution causes a complicated influence analysis of the partial threats that occur in several trees. In this paper, a method for threat analysis is described which enables a complex influence analysis of partial threats and a choice of optimal set of security countermeasures.
