Full textThesis for scientific degree of candidate of technical sciences, specialty 05.13.06 – information technologies. – National Technical University "Kharkiv Polytechnic Institute", Kharkov, 2016. The most important scientific and practical problem of identification of the financial condition of the company in terms of fuzzy data values controlled by financial indicators is considered in the thesis. Based on the analysis of traditional methods of solving this problem are identified the lack of them: insufficient consideration of the uncertainty of input data. In this regard, improved methods of multivariate discriminant analysis, cluster analysis and regression analysis for the case when the initial data – fuzzy numbers. For small sample output data suggested the procedure for building diagnostic information processing expert system that combines regression approach and Bayesian inference mechanism. The calculation of the regression coefficients method used pairwise comparisons. The method of predicting the time series correlated to the small sample of the original data, as well as a method of forecasting the series, given its wavelet model. On the basis of the developed methods based information technology diagnosis financial condition of the company. The proposed technology is integrated into the software package for the credit assessment of the bank borrowers showed more early detection of deterioration in the financial condition of borrowers compared to the old technology. The results obtained allowed to take timely management decisions and prevent increase of bad debts in the loan portfolio of the bank.

The thesis is dedicated to the enhancement of efficiency and reliability of the identification of the computer systems of critical application state by means of development and improvement of methods and means of recognition of anomalies and abuses. The analysis of the scientific and technical problem of the indication of CSCA for data protection was carried out. The examination of main dangers and factors affecting the state of the information protection in the computer systems of critical application was done. The requirements of efficiency and reliability of the identification of the CSCA state, data safety under external influence, functional criteria of information protection were studied. It was shown that the system of indication of the CSCA state was one of the multilevel tools for information protection and consist of two classes of methods: the anomaly identification methods and the abuse identification methods. It was found that the main disadvantages of the anomaly and abuse identification methods were a neglect of fuzzy set factors and low adaptation to dynamic changes of the initial dataset structures and external effects that leads to the decrease of efficiency and reliability of the CSCA identification. The conclusion of perspective of the direction of development and investigation of complex methods of the identification of the CSCA state was drawn. A scheme of the identification of the CSCA state that includes the subsystem of the anomaly and abuse identification was proposed. The basis of performance of the abuse identification subsystem is complex use of intelligent classification methods that includes the neural network ART-1, the improved models of fuzzy output and the probabilistic automaton. Complex use of the statistical methods of classification and the decision support systems based on discriminant, cluster, Bayes classifiers adapted for the evaluation of performance parameters of the CSCA with fuzzy signs serves as a basis for performance of the anomaly identification subsystem. Enhancement of the discriminant analysis method under the condition of fuzzy input data was performed for the two-alternative classification. It was based on the analogies of theoretic and probabilistic characteristics of fuzzy numbers, particularly, the expected value, the dispersion of correlation coefficients, used for the standard calculation scheme by means of the solution of the linear equation system and the classification of the object state. In the present work the enhancement of the cluster analysis under condition of fuzzy specification of the point coordinates (the results of measurements of controlled parameters) and the centers of cluster groups, defined by membership functions, was done for the multi-alternative diagnostic. The procedure of the comparison of fuzzy distances between the objects of clustering and the group centers, based on the comparison of fuzzy function of distance difference with zero was proposed. The rules for the result treatment of the comparison of fuzzy number with zero were developed. A criterium of self-descriptiveness estimation of the performance parameters of CSCA under fuzzy input data, the value of which belongs to the final range, does not depend on the parameter membership function type and on the rules of inclusion of the function into evaluation expression, was found. The self-descriptiveness rate of the controlled fuzzy parameters, described by gaussian and exponential function of membership, was obtained. The criterium of self-descriptiveness of fuzzy parameters based on the surface evaluation of the area of intersection of the state membership functions was developed. An expert system with non-productional mechanism of logic inference based on modified Bayes classifier was created for identification of the CSCA state with infinite numbers of controlled parameters. An express method of identification of the CSCA state relied on complex use of statistic methods of classification including BDS test, the evaluation of Hurst exponent and Shewhart charts, CUSUM and EWMA, as components of the subsystem on anomaly recognition, was worked out. A new parameter of normal performance of CSCA based on the jitter value of the system was synthesized and a template of normal behavior of CSC A arising from BDS test and Hurst exponent values was proposed. The templates of the normal system state of CSCA relying on Shewhart charts, CUSUM and EWMA were built. A classification method of CSCA state based on the neuron network ART-1 that included complex use of ART-1 blocks was developed. A program model developed to imitate intrusions into CSCA allowed to analyze the prototypes of malware, to distinguish the most informative descriptors and to use them as masks to obtain binary signatures of malware. The obtained binary vectors were used as examples in system training and in similarity measure search. The use of the proposed method improved the efficiency of identification of the CSCA state. A method of identification of the CSCA state relying on the system of fuzzy output, which differs from the well-known by the use of minimization procedure of number of rules linking input and output fuzzy variables, was suggested. It allowed to improve efficiency of the identification of CSCA state. An identification method of computer system of critical application state was proposed on the basis of the probabilistic automaton. The method consists of the model of generation of an automaton structure and the procedure of its modification. The main feature of the method is an adaptation of the generation procedure of the automaton structure to the situation of recognition of identical scripts by means of the automaton structure rebuilding upon coincidence detection and recalculation of the probability of transfer between states. The improved method allows to accelerate the process of revelation of anomaly behavior of the CSCA as well as to detect the abuse of computer system, signature scenarios of which only partially match the examples used for the generation of the automaton structure. On the basis of ROC-analysis a comparative study and an estimation of reliability and efficiency of developed methods and means of anomaly and abuse identification in CSCA was performed. Practical recommendations on the use of the methods and means of the anomaly and abuse identification of the CSCA were proposed and corresponding recommendations on operation of sensitivity level and classifier specification to regulate the level of false-positive and false-negative identification were suggested.
