Over the last decade, the area of electroencephalography (EEG) witnessed a progressive move from high-end large measurement devices, relying on accurate construction and providing high sensitivity, to miniature hardware, more specifically wireless wearable EEG devices. While accurate, traditional EEG systems need a complex structure and long periods of application time, unwittingly causing discomfort and distress on the users. Given their size and price, aside from their lower sensitivity and narrower spectrum band(s), wearable EEG devices may be used regularly by individuals for continuous collection of user data from non-medical environments. This allows their usage for diverse, nontraditional, non-medical applications, including cognition, BCI, education, and gaming. Given the reduced need for standardization or accuracy, the area remains a rather incipient one, mostly driven by the emergence of new devices that represent the critical link of the innovation chain. In this context, the aim of this study is to provide a holistic assessment of the consumer-grade EEG devices for cognition, BCI, education, and gaming, based on the existing products, the success of their underlying technologies, as benchmarked by the undertaken studies, and their integration with current applications across the four areas. Beyond establishing a reference point, this review also provides the critical and necessary systematic guidance for non-medical EEG research and development efforts at the start of their investigation.

Information security risk assessment is an important part of enterprises’ management practices that helps to identify, quantify, and prioritize risks against criteria for risk acceptance and objectives relevant to the organization. Risk management refers to a process that consists of identification, management, and elimination or reduction of the likelihood of events that can negatively affect the resources of the information system to reduce security risks that potentially have the ability to affect the information system, subject to an acceptable cost of protection means that contain a risk analysis, analysis of the “cost-effectiveness” parameter, and selection, construction, and testing of the security subsystem, as well as the study of all aspects of security.

The article deals with the development, implementation and research of the spectrum analyzers that can be used in sensor networks and Internet systems of things. As an operating frequency range, 2.4–2.5 GHz ISM is selected. At the stage of hardware selection, a comparative analysis of existing available microcontrollers for the analysis of the spectrum, the choice of hardware interfaces, the ordering of the required modules and electrical components, as well as the input control is carried out. During development, several variants of spectrum analyzers on the basis of microcontroller and TI Chipcon СС2500 microcontrollers with USB interfaces, as well as Cypress CYWUSB6935 modules with LPT and USB interfaces, have been implemented. At the development stage, the development of the printed circuit board, its fabrication, component assembly, microcontroller programming, the verification of the assembly's robustness, making corrections, connecting to a personal computer and assembly in the case have been carried out. An analysis of existing software for collecting information on the state of the wireless broadcast is also conducted. According to the results of comparative experiments of various collections of spectrum analyzers, spectrographs for different types of signals were obtained. On these typical spectrographs a comparative analysis of the work of various prototypes was conducted. The offered approaches to building sensors on the basis of spectrum analyzers allow to create low-power modules for embedding in existing wireless information networks of enterprises for prevention of inter-channel interference and ensuring the integrity of data transmission. As a result of experiments, it is evident that not all existing modules are very different in characteristics, and the quality of their work is directly related to the type and quality of the antenna. The article gives the basic electric circuits, a list of elements, examples of PCBs, programmers, software and prototypes.

The article presents a study using attacks such as a fake access point and a phishing page. The previous publications on social engineering have been reviewed, statistics of break-ups are analyzed and directions and mechanism of realization of attacks having elements of social engineering are analyzed. The data from the research in three different places were collected and analyzed and the content statistics were provided. For comparison, three categories of higher education institutions were chosen: technical, humanitarian and mixed profiles. Since the research was conducted in educational institutions during the week, most students in the experiment and graduate students took part in the experiment. For each educational institution, a registration form template was created that mimicked the design of the main pages. Examples of hardware and software implementation of a typical stand for attack, data collection and analysis are given. In order to construct a test stand, widely available components were chosen to show how easy it is to carry out attacks of this kind without significant initial costs and special skills. The article provides statistics on the number of connections, permission to use the address of the e-mail and password, as well as permission to automatically transfer service data to the browser (cookies). The statistics are processed using specially written algorithms. The proposed approaches to solving the problem of socio-technical attacks can be used and implemented for operation on any objects of information activity. As a result of the experiments, it is clear that the awareness of users of even technical specialties is not enough, so one needs to pay particular attention to the development of methods for raising awareness of users and reducing the number of potential attacks on objects of information activity.
