EFFICIENCY OF THE INDICATORS INVESTMENT CALCULATION METHOD IN THE INFORMATION SECURITY SYSTEM OF INFORMATION OBJECTS

Abstract
The article analyzes publications on the evaluation of investments in information security (IS) of objects of informatization (OBI). The possibility and necessity of obtaining the necessary data have been substantiated, contributing to a reliable assessment of the effectiveness of measures aimed at increasing the company’s IS. In the study process, the modelling methods have been used. A methodology is proposed for calculating indicators from investment activities in the context of increasing IS metrics of OBI. A specific example of such simulation is described. The proposed methodology provides an assessment of the damage prevention from a cyber-attack. The amount of the damage prevention from a cyber-attack is taken as a basic indicator for calculating the economic effect of investing in information security tools (IST). The performed simulation modelling allowed taking into account the relative uncertainty of the real situation with IS of OBI. The conducted study will help practitioners in the field of IS to obtain informed decisions to increase the efficiency of investment projects in the field of IS for OBI, using the approach outlined in the study. Unlike the existing ones, the proposed methodology takes into account both direct and indirect factors of investment projects in the field of IS of OBI
