Synthesis of a security management model for cyber-physical systems.

Cyber-Physical Systems (CPS) are systems consisting of various natural objects, artificial subsystems, and controllers, which make it possible to represent such an entity. Cyber-physical systems provide close communication and coordination between computing and physical resources. CPS provides close communication and coordination between computing and physical resources. Computers monitor and control physical processes using a feedback loop where what happens in physical systems affects computation, and vice versa. This type of systems is actively implemented in industrial, urban, and residential infrastructure, allowing for more efficient use of resources, improved quality of management and feedback. As complex heterogeneous distributed information management systems, CPSs are susceptible to cyber threats. The peculiarities of construction and functioning of cyber-physical systems require the division of threats and attacks into two classes. The first includes malicious actions aimed at violating the confidentiality, availability, and integrity of data processed in the system. Ensuring the security of conventional information systems is aimed at preserving these very properties. The second class includes cyber threats, the successful implementation of which can disrupt or modify the system's management and control processes. Depending on the CPS's objectives and the degree of criticality of the real-world processes it controls, disturbance of flows within it can lead to serious consequences, such as great material damage or threat to human life and health. With the rapid development and improvement of Programmable Logic Controller (PLC) devices and their cost reduction, the smart home concept is becoming increasingly popular. This approach involves integrating PLCs communicating with each other and the control center via multiprotocol computational public access (Internet) networks into the residential infrastructure. Thus, a smart home is built on the basis of CPSs. In this application environment, it is essential to ensure the information security of the cyber-physical systems used. To ensure the required level of security of these objects, it is necessary to effectively solve the problems of managing the process of ensuring their information security. On this basis, the paper proposes an approach to develop a model of the CPS security management process on the example of a smart home. [ABSTRACT FROM AUTHOR]
