Abstract
We proposed an architecture for a control system of the object of informatization (OBI) with the subsystem of intelligent support for making decisions on the operational management of cyberprotection. The proposed architecture, in particular, can be used under conditions of the incompleteness of knowledge about the state of OBI protection. We developed a model for the operational management of cyberprotection at OBI and formed a rational complex of means. The model is based on the morphological approach. The model allows, taking into account morphological matrices for each of the five proposed perimeters prepared by the intelligent decision-making support system (IDMSS), generation of variants of sets that consider the compatibility of software and hardware tools of protection. It is proposed to make the choice on the optimal variant of a set for the perimeter using an objective function that maximizes the ratio of the summary indicator protection of information to the summary indicator expenditures. The software is realized and tested under real conditions of IDMSS in the contours for the organizational-technical and operational management of the OBI protection. An improved architecture of IPCS is different from the existing solutions in the possibility of simultaneous optimization of sets of software and hardware tools for the examined perimeters of OBI, for both centralized and decentralized variants for processing the information. In this case, an analysis of the level of of OBI is performed in real time. It is proven that the use of the developed IDMSS makes it posible to significantly reduce the planned spending on an system, as well as reduce the time it takes to inform decision-makers about security incidents.
Highlights
Current level and further prospects for the development of information– communication systems (ICS) in different areas of human activity cannot be imagined without special attention paid to the issues of information (IS) and cybersecurity (CS)
Since the objects of control, information protection control systems (IPCS), are rather complex organizational-technical structures (OTS) that operate under conditions of uncertainty, effective management of such systems should be based on the innovative information technologies of decision making support that relate to IS and CS
Based on the analysis of possibilities to improve IPCS of OBI, we propose the model for operational control over intelligent decision-making support systems (IDMSS) with IS, which allows increasing the quality in planning the structure of IP systems (IPS)
Summary
Current level and further prospects for the development of information– communication systems (ICS) in different areas of human activity cannot be imagined without special attention paid to the issues of information (IS) and cybersecurity (CS). This is, in part, due to the growing number of cyber threats and destructive impacts on the objects of informatization (OBI). Since the objects of control, IPCS, are rather complex organizational-technical structures (OTS) that operate under conditions of uncertainty, effective management of such systems should be based on the innovative information technologies of decision making support that relate to IS and CS.
