The aim of the work is to create a scientifically grounded methodology and the theoretical basis for forecasting and warning about unauthorized access (UA) in special information networks (SIN) to increase their level of security.
Author proposed new method of forecasting the state of the SIN parameters, which allows obtaining the forecast of the parameters of the UA by adapting the mathematical expressions and relations for the analysis of the vector a posteriori random process. Author proposed new method of determination of the set of predictive parameters based on the selection of control on dependent and independent parameters of a controlled network, which allows to increase the reliability and efficiency of the forecast of the UA; Got further developed the theory of using Bayesian verification of forecasts by adapting the relationships to calculate the a posteriori accuracy of estimating the parameters of the predictions of the UA in the SIN, which allows them to be used in the case of a joint decision of the tasks of checking the predictions of the UA and estimating the parameters for the optimal algorithm for predictions SIN in the general case. Proposed the optimal decision-making rules that can be used for the recognition-estimation of UA predictions in SIN, depending on the task set. Improvement of the methods of comparative estimation of the effectiveness of rules for checking the predictions of the UA, which allowed to calculate the effectiveness of the successive Wald rule in comparison with the uniformly best non-consistent rule. Structural information processing algorithms that control the parameters of the SIN for prediction and prevention of UA for three cases from the point of view of the prognostication procedure are proposed and on the basis of them implemented the algorithms of forecasting and warning about the UA in the case of parallel and sequential processing of information.
The results of the work were included in the doctoral dissertation of Opirskyy I.R. and as well as implemented in: State Budget work SB/CYBER and faculty researchworks at the National University "Lviv Polytechnic"; target complex research program of the National Academy of Sciences of Ukraine "Resource-2"; software modules of «Cipher BIS»Ltd and Defense Ukraine Llc; scientific and development work of the State Research Institute of Special Communications and Information Protection; activities of the Western Regional Educational and Scientific Center for the Protection of Information; educational process of the Department of Information Protection of the National University "Lviv Polytechnic".
