    Machine Learning Models Stacking in the Malicious Links Detecting
    (Igor Sikorsky Kyiv Polytechnic Institute, 2023) Khukalenko, Yevhenii; Stopochkina, Iryna; Ilin, Mykola
    An analysis of the performance of various classifiers on address and network groups of features was performed. A new classification model is proposed, which is a stacking of 3 models: kNN, XGBoost and Transformer. The best model for stacking was experimentally determined: Logistic Regression, which made it possible to improve the result of the best available model by 3%. The hypothesis that stacking a larger number of worse models has an advantage over stacking a smaller number of more productive models on the used data set was confirmed: regardless of the choice of stacking metaalgorithm, stacking of three models showed better results than stacking two.

    Methods of counteraction of bypassing two-factor authentication using reverse proxy
    (Igor Sikorsky Kyiv Polytechnic Institute, 2021) Vlasenko, Andrii; Stopochkina, Iryna; Ilin, Mykola
    The existing solutions for counteracting and preventing the interception of data and tokens of two-factor authentication are considered. Features that may indicate the presence of a silent reverse proxy server are chosen. It is proposed to analyze the information about additional time anomalies, which are usually created by the proxy server. The advantage of this approach is that the time characteristics information is generated on the client-side, and the malicious proxy server cannot modify it. Machine learning methods were used to detect implicit signs of the presence of a proxy server. A new method of detecting a silent reverse proxy server that satisfies the following conditions is proposed: 1) the human factor is minimized, 2) use by an individual user is possible, 3) the method has an acceptable impact on performance and can be used in real-time.

    Models of Denial of Service Attacks on Cyber-Physical Systems
    (Igor Sikorsky Kyiv Polytechnic Institute, 2023) Ovcharuk, Mykola; Ilin, Mykola
    Mathematical models of denial-of-service attacks are investigated in the paper. Threats of kinetic impact on systems in cyberspace are considered. Targeted computer systems and systems with low and high-security levels were studied. The simulation results demonstrate a successful resolution of the task.
