Abstract

The article is devoted to solving a relevant scientific and practical problem - the development of a mathematical model for calculating the value of information of the institution. The following concepts are interpreted: the value of information, the level of importance of information, the time of final aging of information and the level of ownership of information used in research on the object of information protection. The indicators by which it is proposed to determine the value of information are considered in detail and its dependence on such indicators is shown. It is proposed to calculate the value of information as the average value of the sum of the relevant coefficients. Each of the selected coefficients is calculated using the ranking method. The importance of the relevant information indicator is determined in accordance with the requirements of the guidance documents on the organization of information security or a specially created group of experts. It is proposed to use the following coefficients: the coefficient of influence of the level of access to information, the coefficient of influence of the time of final aging of information, the coefficient of influence of information importance and the coefficient of influence of the right to information. The adequacy of the mathematical model for calculating the value of information of the institution was checked. It is established that the information that has the highest level of restriction of access, the highest level of importance and the right to information belongs to the state, has the greatest value for the institution. An example is given in which a list of information that needs protection in the institution is compiled and the value of information from this list is calculated. The mathematical model of calculating the value of the institution's information allows you to justify the need to take additional measures to improve the comprehensive system of information protection in the institution's automated systems and to better approach the issue of forming a model of information threats in information and telecommunication systems. Keywords: value of information; ownership of information; time of final aging of information; level of importance of information.
