Development of an Information Security Management Model for Enterprise Automated Systems.

This article proposes an information security management system (ISMS) model for automated data processing systems of critical applications (ADPS-CAs). The model allows users to carry out an assessment of the risk level for information security (IS) purposes and provides support for decision-making related to countering unauthorized access to the information circulating in an ADPS-CA. Further, this article analyzes the effect of a control parameter on the probability of launching an information integrity monitoring service (IMS) during a procedure that launches a typical ADPS-CA and its IS subsystem. The results present system quality indicators for protecting information from unauthorized access. The simulation was performed in relation to automated workstations as part of the ADPS-CA of a large enterprise.
