Abstract: This work describes the module of the "RiskPanel" software system, performing risk analysis of multi-step computer attacks. The module is based on statistical analysis of actual computer attack precedents. At the user's request the system calculates objective probability of information security risks, taking into account all possible multi-step attacks (i.e. possible combinations of known attacks). The estimation of probability is presented as an interval because we don't always have a full description of real attacks. The task of this work is described using the model-theoretic formalism. The first step is to build a knowledge base of computer attacks. The formal description of the knowledge base structure is made with the Description Logic. Formalization of estimated (fuzzy) judgments is made in the language of the Fuzzy Model Theory. The article contains algorithms for calculation of probabilistic risk intervals and describes program implementation of the developed methods.
