System analysis for evaluating the effectiveness of tools for information security

Abstract

The paper focuses on important elements of system analysis such as principles, indicators and criteria of system efficiency. The aim of this work is to show the possibility of applying system analysis and system approach in the field of information security. In this field the 3rd principle of the theory of systems and systems analysis (the maximum efficiency of the system) and the 15th principle of the systems approach, associated with optimal efficiency, are specially highlighted. The main focus is on the effectiveness of the system, which can be assessed using special indicators. We have used the necessary principles and methods of system analysis, as well as special software for applying the elements of system analysis for the performance indicators. In this case special software is considered as a tool for solving problems of system analysis in the field of information security. We introduced an indicator and criterium of system efficiency associated with the difference in reduced costs. The result of the optimization of the information security effectiveness indicator is demonstrated on a special example. The researchers use the system analysis elements. Researchers solve optimization problems. Recommendations were developed for solving typical educational problems. It is concluded that it is necessary to pay more attention in the framework of the educational process to the elements of system analysis.
