Authors: Kayumova T R , Myshlyavtsev A V , Stishenko P V 
Published: March 2022

Abstract
In this work we have studied the behavior of oxygen adsorbed on the MXenes M2CO (M=Ti, V, Nb) surface by the density functional theory and Monte Carlo methods. An approximation for the lateral interactions potential has been constructed that has the form of a pair potential. We have carried out the quantitative assessment of the errors of the pair potential. Using SuSMoST program we have constructed isotherms of adsorption. The results showed a non-trivial phase behavior of the adlayer: we observed three phases characterized by the 1/3, 1/2 and 2/3 coverage. It has been predicted that complete oxygen removal from the MXenes surface is possible at temperatures above 500 K.
Microhardness and wear resistance of a high-entropy coating FeCrNiTiZrAl
Authors: Yurov V M , Eremin E N , Guchenko S A 
Published: March 2022

Abstract
In this article, the microhardness and wear resistance of the high-entropy FeCrNiTiZrAl alloy are studied on model specimens and on turbine blades made of 20Kh13 steel. The alloy was made by mechanical alloying and subsequent annealing in a vacuum furnace. The study showed that the obtained alloy is a high-entropy alloy with a microhardness μ = 740 HV, which is at the level of the microhardness of metallic glasses, but 2-3 times higher than the microhardness of stainless steels. The friction coefficient of the FeCrNiTiZrAl coating is k = 0.06, which is 10 times less than the friction coefficient of the titanium nitride coating (k = 0.65). The wear resistance of the high-entropy FeCrNiTiZrAl coating is much higher than that of stainless steels, and it leads to the fact that the cost of titanium nitride coating on turbine blades is 2 times higher than the cost of FeCrNiTiZrAl coating, that is, the economic effect is obvious.

Python as an automation tool in IS. Monitoring the relevance of protection against malicious code
Authors: Dronov V Y , Dronova G A 
Published: March 2022

Abstract
One of the necessary, periodically performed by information security (IS) department procedures is to assess the level of compliance of the actual state of any IS measure with the established requirements. These procedures involve a significant amount of manual work, which leads to a waste of time, human, technological resources. In this case it is not always possible to provide a high level of reliability of the results. To reduce costs, increase the degree of reliability and accuracy of the results of assessment of the IS state, and, accordingly, increase the level of confidence in the IS state assessment, it is possible by the use of “small automation” means when performing routine operations of collection, correlation, normalization, analysis of data sets. The most acceptable means of automation is the programming language python, which, in addition to convenience of use, powerful functionality, has an extensive analytical apparatus. This article discusses the use of python as a “small automation” tool for monitoring the relevance of antivirus protection system.

Abstract
The main element of a complex system that determines its performance and efficiency is its management system. Modern management systems are widely used, including in the management of teams of people united by common goals (organizations, departments, groups of developers, etc.). Information security is no exception - it is not enough to saturate the division responsible for information technology security with personnel, technical systems of information protection, it is necessary to ensure the effectiveness in achieving the goals, which is not possible without an appropriate management system. Information security specialists in organizations of various forms of ownership often face the problem of ensuring effective and efficient protection of information assets. Availability of international and national standards, regulatory documents of regulators does not ensure the achievement of high performance and efficiency indicators. The achievability of these indicators is determined by setting and achieving a number of goals, based on certain strategic principles of information security management system.
Python as an automation tool in IS. Protecting Database Access in Python
Authors: Dronov V Y , Dronova G A 
Published: March 2022

Abstract
The activity of modern organizations, regardless of the form of ownership, is highly risky. There are up to 600 risk factors in total. It is possible to reduce risk levels only after assessing them. The basis of risk assessment is analytical processing of information relating to the sphere of organization’s activity. The information to be analyzed is usually accumulated in databases. This information is usually accessed with SQL queries and analyzed with application software. The most rational variant is when the business unit employees are able to select the data from the database and perform their analytics independently. The most convenient, both for sampling information from databases, and for its analysis to use python. However, python, which is an interpreted language, has a disadvantage in terms of information security - access parameters, including user login and password, database connection parameters, are located in the program body in clear form. The option proposed in this article allows you to reduce the risks of privacy violation when accessing the database.

Published: March 2022

Abstract
One of the most important issues in the field of information security has been and remains the issue a reliable user’s authentication. A special place among the possible authentication methods today is occupied by behavioural biometrics, which have a high degree of reliability. A keystroke dynamic, as a type of behavioural biometrics, is also capable of providing a high level of protection of information systems in the case of correctly selected characteristics. This article shows that external factors, including the psychophysiological state of a person, can also influence the authentication process by keystroke dynamics. In the paper, the state of the user was assessed in the process of collecting a sample of keystroke dynamics and a conclusion was made about the presence of such an influence.

Development of metrological support for nucleic acid measurements
Authors: Vonsky M S , Runov A L 
Published: March 2022

Abstract
Measurements of nucleic acid have become an essential part of analytical applications in many fields including life science, medicine, veterinary medicine and biotechnology. Peculiarities of these measurements are largely determined by the uniqueness of quantity and analyte definitions. Quantitative PCR, applied for routine nucleic acids measurements, is a relative method demanding external calibrators with quantity values traceable to corresponding reference materials. Direct nucleic acid measurements became possible after introduction of the digital PCR (dPCR) method. Ensuring accurate, comparable and traceable to SI nucleic acids measurements is the focus of Nucleic Acid Analysis Working Group of the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology. A number of pilot and key comparisons carried out by Working Group have shown that application of dPCR allows participating National Metrological Institutes to obtain comparable results of measurements of the sequence copy number concentrations and copy number ratios.

Characterization of oxyanions of chlorine by multipath titrimetric approach for drinking water quality control
Authors: Asakai Toshiaki 
Published: March 2022

Abstract
The analysis of oxyanions, perchlorate, chlorate, chlorite and hypochlorite ions, is of interest, especially from the viewpoint of evaluating drinking water quality. Instrumental analyses are generally performed to quantify them, and require a standard solution of corresponding ions; however, no standard solutions characterized by a metrologically valid procedure have existed. In the present study, perchlorate, chlorate and chlorite ions were characterized by performing multipath titration techniques. This technique is an approach to determine the amount of substances in chemicals by employing different stoichiometric reactions. It has decreased the risk and the contribution of unknown biases that each measurement method has, and gives further reliable results than those based on a conventional single titration method. The comprehensive evaluation of the measurement uncertainties for these assays was carried out, resulting in the establishment of the measurement methodologies for oxyanion standards.

Authors: Dyachkova V G , Kraynova M D 
Published: March 2022

Abstract
Measuring the activity of radionuclides is one of the most popular directions in the field of ionizing radiation measurements. The fact that ensuring the unity and reliability of measurements of the activity of radionuclides is the most important task is obvious. Radionuclide sources of ionizing radiation for metrological purposes are necessary for the calibration and graduation of radiometers and spectrometers and are also used as control sources. VNIIFTRI develops and manufactures various types of metrological sources: point sources, surface sources, simulators of radioactively contaminated environmental objects, which, in turn, are divided into solid-state and bulk sources. The use of these sources avoids a significant increase in the error of measuring instruments.
