Description

The dissertation investigates the issues of dependability of the Internet network infrastructure that were studied by using the network topology analysis, graph theory and network modelling. The object of the study is the Internet network infrastructure, based on autonomous systems and interconnecting lines. Stable functioning of the Internet network determines the availability of information, electronic commerce, control of remote objects, etc. The main objective is to develop the methodologies and algorithms for analysing the Internet network infrastructure and controlling the reliability of functioning. The scope of application of the study is the supervision and regulation of continuity of the Internet.

The following main tasks are solved: development of the topological scheme of the Internet network, selection of models and tools for analysis; the Internet network connectivity analysis for the purpose of identification of the critical network elements, whose violations would result in loss of connectivity of the network; as well as development of the model for monitoring of the critical elements of the Internet network and cyber-attacks simulation experiments.

The scientific work consists of the general characteristic of the dissertation, 5 chapters, conclusions, list of literature, list of publications and annexes.

The introduction reveals the investigated problem, importance of the thesis and the object of research and describes the purpose and tasks of the paper, research methodology, scientific novelty, the practical significance of results examined in the paper and defended statements. The introduction ends in presenting the author’s publications on the subject of the defended dissertation.

The first chapter is dedicated to the santific researches of the networks and information security incidents management model (CERT) overview ant its optimization. The second chapter analyzes the topology of the Internet network by applying the columns theory and suggests a classification of autonomous systems and their connecting lines. The third chapter is dedicated to the development and application of the methodology for searching for the critical elements of the Internet network infrastructure. A methodology and algorithm for elements monitoring is suggested. In the fourth chapter the impact of cyber-attacks on the functioning of the Internet network infrastructure is modeled and examined. Fifth chapters covers the measures for the improvements of Internet network dependability and forms future internet regulation perspective.

6 articles focusing on the subject of the discussed dissertation are published: 4 articles – in scientific papers in the Thomson ISI register, 2 articles – in conference materials. 9 presentations on the subject have been given in conferences at national and international level.
