Функціональна модель підсистеми безпеки системи управління безпроводовими сенсорними мережами військового призначення

Formulation of the problem in general. The development of modern information and communication technologies in the military requires improving wireless sensor network management systems. An effective combination of monitoring and telecommunication processes with the guarantee of confidentiality, integrity, availability and authentication of information is possible only if there is a comprehensive wireless sensor network management system, an essential component of which is the security subsystem. The aim is to develop a functional model of the security subsystem of the military wireless sensor network management system to ensure the security of its operation and optimise its impact on other subsystems of the management system at all levels of the network. Analysis of recent research and publications. The scientific sources analyse the security of mobile radio networks, options for building attack detection systems, and identify the advantages and disadvantages of various methods and mechanisms for protecting wireless sensor networks. Based on the results, it is concluded that there are still unresolved issues regarding the functioning of the security subsystem of these networks. Presenting the primary material. An analysis of scientific publications is carried out, and it is determined that the model of a security system with complete overlap (Clements-Hoffman model), based on the theory of graphs, fuzzy sets, and probabilities, is considered the basis for formalising the description of the functioning of security systems. A functional model of the security subsystem has been developed, consisting of the following modules: authentication and access control, encryption, intrusion detection and prevention, security policy management, and software update and recovery. This model, which provides complete overlap of threats, is formalised in the form of a mathematical description, increasing network resistance to attacks. Elements of scientific novelty. The scientific novelty of the work lies in synthesising existing protection methods and security mechanisms into a single subsystem that allows for a comprehensive assessment and minimisation of the risks of attacks on a wireless sensor network for military purposes. The proposed approach provides adaptability and integrates into existing control systems. Practical significance of the article. The study's theoretical significance lies in developing methods for mathematical modelling of threats and constructing a sustainable security management architecture for wireless sensor networks. The practical value of the research results lies in the possibility of their implementation in military and special communication systems, which provides increased security of critical information and communication systems in modern conditions. Conclusion and the perspectives of future research. For military purposes, the functional model of the security subsystem of the control system of wireless sensor networks provides an integrated approach to protection at all control system levels. The basic and general level of security of the control system is formalised, which will allow further evaluation of the effectiveness of the proposed security measures Directions for further research are the development of methods and techniques for automatic detection of anomalies and intrusions using artificial intelligence technologies for adaptive security management in the face of dynamic changes in network topology and threats.
