The technique of substantiating the rational composition of information security tools with constrained resources63_2.pdf

Finding the optimal structure of an information security system is an important task complicated by its uncertain, stochastic and nonlinear nature especially, if resources are constrained. The article considers a mathematical model for determining the cost of damage prevented by information security tools, and the cost of their installation and maintenance. The optimization criterion is the minimum cost of the damage prevented. Task variables are the number of different types of security features installed in the security system. The authors propose a methodology to substantiate rational composition of information security tools, taking into account economic constraints.

Calculation of safety index for foreign origin electronic components62_4.pdf

The article deals with problems arising from the use of foreign origin electronic components, being off the line in standby (storage) mode during operation with periodic monitoring of their operability, as well as with possible ways to solve these problems. It proposes the method of assessing the safety index based on determining the characteristics of foreign origin electronic components for the standby (storage) mode. The method is implemented using mathematical models with the activation energy of physical and chemical processes of electronic components degradation. The use of mathematical models to solve the problem may allow forecasting the reliability of products in the most efficient way. The authors give calculations and comparative analysis of the minimum service life (minimum shelf life) at an elevated temperature for several groups of foreign origin electronic components and for several models of external influencing factors.

Reliability, safety index, foreign origin electronic components.

Information Security Method Based on User Activity Monitoring of Distributed Computing Environment 57_4.pdf

The article analyzes the security features of information resources of distributed telecommunication systems. Geographically distributed computing network is a set of network equipment and communication lines designed for data exchange between user workstations and functional subsystems. Given that more than 90% of the organization’s information is now in electronic form, the problem of ensuring the protection of information circulating in the computer network is becoming an extremely important task. In this regard, the organization of the network structure is associated with the necessary settings of security policies of network users. At the same time, the most real and numerous internal threats that most organizations have remain out of sight. The article describes the systems designed to protect the computer network from an internal intruder, using the control of network connections, accounting and analysis of network traffic. The principle of definition of actual types of activity of users which is based on the analysis of statistical parameters of sessions on various types of network activity, their comparison with profiles of users allowing to classify sessions of network exchange is formulated. Grounded steps and the classification algorithm network activities and separate instances of network sharing in the network activities.

A Coefficient Method for Calculating the Reliability of Functional Part of Power Supply Pcb 56_14.pdf

The reliability of electronic equipment has been the focus of the attention for many decades. The actuality of that grows along with the miniaturization of electronic components and the density of attachment in electronic equipment. The process of reliability calculation becomes more complex and takes more time in view of the growth of type and amount of applied electronic components. Nonfailure operating probability, failure intensity, and mean time to failure are basic qualitative characteristics of the reliability. The dangerous failures of electronic components can have critical and catastrophic consequences in the functionality of electronic equipment. The article deals with the procedure of the reliability calculation using various coefficients. Different mathematical models can be used for the same task of the reliability calculation. In order to solve the tasks, various methods can be used. All these facts may cause different results.Authors represent an approach to the coefficient method allowing to carry out the reliability calculation with higher precision and fidelity. The coefficient method is usable for comparing different ways for reliability calculation.

Reliability, coefficient method, time to failures.

The Mathematical Model of the Static Pressure Flowing Reciever 000_8.pdf

The article considers the matters of constructing mathematical models of the static pressure following receivers (SPFRS) designated for sensing static pressure on helicopters in a range of airspeeds to 250…350 km/h. SPFRS consist of contracting and diffusing parts. The mathematical model of SPFRS was developed in accordance with results of experimental researches for defining static pressure, dynamic pressure, speed, speed inaccuracy, altitude inaccuracy. The adequacy of the obtained mathematical models is checked through the comparison with the results of experimental researches. The models allow getting reliable data at the contractor convergence angle in 30-70 degree, the diffuser aperture angle in 8-14 degree, the diaphragm coefficient in 0.15-0.45, windblast speed in 20-250 km/h. The influence of separate components (a contractor and a diffuser) on SPFRS pressure coefficient and correlation between experimental data and the results obtained with the mathematical model are considered. With the use of the obtained mathematical models, the process of developing receivers with predicted metrological characteristics can be automated. The ability to take up receivers with required form factors for the specific control object on the original development cycle promptly has been appeared.

Simulation Operation Model for Radio Equipment of Computer-aided Data-exchange System 20_3.pdf

The article describes a simulation model of radio-equipment operation for computer-aided data-exchange system created in order to evaluate influence of failure rate of radio-equipment devices and time for their recovery, on probability of uninterruptible data-exchange between computer-aided data-exchange systems of two ships during a long-time period. The model of the operation process of radio equipment is developed using a mathematical scheme of queueing system - Q-scheme. The model response is an evaluation of the probability of uninterruptible data-exchange between computer-aided data-exchange systems of two ships during a long-time period. The model factors are the following reliability parameters of each radio equipment: failure rate and recovery time. The article also gives a block-diagram of general algorithm of the radio-equipment operation process and block-diagrams of procedures to define and change states of radio-equipment devices simulated by queueing-system channels. The simulation model is at the level of software implementation. The result of the software implementation of the simulation model with values of the reliability parameters of radio-equipment devices, given by users, is an interval evaluation of probability of uninterruptible data-exchange between computer-aided data-exchange systems of two ships during a time period given by users. The required accuracy and adequacy of the evaluation are ensured by a required number of software iterations, calculated by the programme, with the same initial data. To evaluate the importance of factors (reliability parameters of radio-equipment devices), a variance analysis of each of them with response has been made. A combination of achievable factor values when response values becomes the largest, has been defined by a method of coordinate raising.

Simulation model, channel state, variance analysis, method of coordinate raising.
