Currently, the software market offers a multitude of diverse DLP-systems designed to protect confidential information from leaks. Since such systems have a relatively high cost, it is advisable to select the optimal option before acquisition and implementation, as incorrect selection will lead to unnecessary costs and ineffective control of information. The paper describes the base of the rules of the fuzzy inference system, designed to evaluate the DLP-system. Practical use of the proposed fuzzy system allows to perform a reasoned choice of such a DLP-system that most fully meets the requirements of a particular organization and provides the required level of protection of information from leaks. At the same time, the evaluation is performed according to several criteria, the values ​​of which, based on expert estimates, are input variables of the fuzzy inference system. At the output of the system of fuzzy inference, a comprehensive evaluation of the DLP-system is formed, which reflects the degree of its suitability for implementation at a particular enterprise.

In this paper we present the method of detecting of low-rate DDoS-attacks on the http-services. A low-rate attack model in the form of a chronological series of events with an additive superposition of attack and normal traffic is used. The task of developing a method of detection of low-rate attacks is formulated as allocation of homogeneous groups (patterns) of the time series, based on pattern recognition models, and the subsequent construction of prediction model for each separate group.

  The article is devoted to improving the performance of cryptographic transformations performed encoders stream ciphers made on the basis of the inner product generator. Such generators are a variety of clock-controlled shift register that can improve the statistical properties of the resulting sequence. The disadvantage is that to get a one character of sequence to submit several clock. The scheme of the inner product generator, based on the algorithm reimplementing feedback shift register recurrence, which allows for one step to produce a single character of sequence, is constructed and described in this article.
