The concept of the Internet of Things (IoT) allows devices to communicate with each other and share resources using the Internet as a wireless medium. In smart homes, IoT allows the owner, who is far from home, to control it via the Internet. The ease of use and rich features of home automation systems have made them popular. Some people need home automation systems to make their home appliances easier and more convenient to operate, and they are also very useful for people with disabilities and the elderly. However, the useful features and functionality of IoT devices do not stop there. Scientific directions are being formed to analyze the efficiency of energy consumption and methods for preventing various disasters, where the main role is played by the technologies of the Internet of things. This article analyzes the standard models of smart home automation devices. The paper discusses the functionality of IoT devices through a virtual environment for building network models Cisco Packet Tracer.

The article describes the algorithmic realisation of a software module for evidence of learner’s identification in the testing process. The advantage of this module is simple operation, ease of implementation and execution as well as convenience of application by various categories of users. The need for such a module was engendered by the problem of examinee identification during testing in the e-learning system. The technology of program module operation is based on forming questions with the use of information stored in the learner’s personal account; the operation result is demonstrated through confirmation or non-confirmation of the examinee’s identity in real time.

In the modern world, the number of different complex technical systems is only increasing every year, and any system incorporates or uses a third-party communication system. Disruption of the communication system and its elements functioning can lead to a situation where a complex technical system cannot realize its functions. It is required to ensure the guaranteed functioning of the communication system and its elements. One of the ways to ensure the stable operation of complex technical systems is the implementation of the control function by the control system, while in the process of system operation it is necessary to take into account not the characteristics and parameters of individual elements that describe their operation, but the ability of the system to perform tasks and functions. The paper proposes an approach to describing the functioning of a communication system through the formation of the system functioning profile, which is a set of matrices, which is used in the control system.

The work is devoted to the problems of protecting the document management system of public administration bodies. The aim of the work is to build a simulation model of the implementation of a targeted computer attack, taking into account the simultaneous (occurring with a slight delay) response of the security tools of the document management system. For modeling, it is proposed to use the apparatus of Petri-Markov networks, combining the representation of the change of states of the attacked system in the form of Markov (semi-Markov) processes and the expressive capabilities of Petri nets to describe the interaction of processes. The constructed model reflects both the specifics of attacks with increased user privileges, and the features of document processing processes, as well as the mechanisms used to counteract unauthorized access. Computational experiments conducted using the constructed simulation model allow us to assess possible risks and make a decision on choosing the most effective system of protection against the considered type of attacks.

The development of an automatic system for installing a magneto-optical magnetic field sensor in a neutral position has been carried out. Installation in the neutral position is carried out by an automatic piezoelectric drive control system based on a microcontroller. A mathematical model is constructed and numerical simulation of the automatic control system is performed. The results and parameters of the simulation are presented. The developed system provides a significant increase in the autonomy of the sensor, which makes it possible to eliminate or significantly reduce the cost of regulating the sensor.

The article describes an approach to the operation of a data transmission network protection system against computer attacks based on a hybrid neural network. It is proposed to use a hybrid neural network as a machine learning method. To calculate the output value of neural network signals, the activation function is used. The neural network model consists of recurrent cells - LSTM and GRU. Experiments have demonstrated that the proposed network protection system for detecting computer attacks based on an assessment of the self-similarity of the system functioning parameters using fractal indicators and predicting the impact of cyber attacks by applying the proposed structure of the LSTM neural network has a sufficiently high efficiency in detecting both known and unknown spacecraft. The probability of detecting known spacecraft is 0.96, and the zero-day attack is 0.8.
