Abstract
An integrated approach to information security management is presented in the form of processes on the decomposition diagram of the IDEF0 model. The analysis of possible damage to information assets is recommended to be carried out according to two groups of criteria with the involvement of experts, based on qualitative scales. Expert analysis of information security threats and vulnerabilities through which they can be implemented is proposed to be carried out in conjunction with the use of qualitative scales, taking into account the presence of implemented control mechanisms in the organization. The results of the analysis are expressed in the form of the total level of the vulnerability group. A matrix for determining the magnitude of information security risk is constructed. The obtained qualitative estimates are compared with the quantitative indicator of the average annual damage and calibrated. As a marker of the effectiveness of protective mechanisms, it is proposed to choose the return on investment ratio. In order to increase the efficiency and convenience of conduct-ing an expert assessment of information security risks, automating the processing of the results ob-tained during the examination, as well as calculations on which the decision-maker can rely, a program was created in the configuration 1C: Enterprise 8.3
