Документ Відкритий доступ System construction of cybersecurity vulnerabilities with Q-analysis(Igor Sikorsky Kyiv Polytechnic Institute, 2023) Polutsyganova, V. I.Today, in order to assess potential cyber threats, it is necessary to conduct a comprehensive assessment of the vulnerabilities of the investigated system. To do this, it is necessary to describe the identified vulnerabilities and consider potential vulnerabilities. In addition, the relationship between system vulnerabilities must be properly assessed. The most common assumption is that all vulnerabilities are independent and are implemented either by random events or by malicious intent. The paper proposes a method that allows modeling the vulnerabilities of complex systems as a whole, taking into account their hidden connections. Q-analysis [2] was used to study the structure of the system of interconnected vulnerabilities that arise in the process of project implementation. An example of the application of Q-analysis methods is presented and an explanation of the nature and impact of some potential threats and their combinations is offered.Документ Відкритий доступ The inverse problem of Q-analysis of complex systems structure in cyber security(Igor Sikorsky Kyiv Polytechnic Institute, 2022) Polutsyganova, V. I.; Smirnov, S. A.It is considered the inverse problem of Q-analysis. In the course of the research, an algorithm for the recovery of simplicial complexes from elementary simplex using local maps and a structural tree was developed. This algorithm will reduce the amount of data stored and improve the management process if the simplicial complex describes a real big complex system wich it can imagine cyber security system.
