Intensive IT development has led to qualitative changes in our living, which are driving current information security (IS) trends and require sophisticated structures and adequate approached to manage IS for different businesses. The wide range of threats is constantly growing in modern intranets; they have become not only numerous and diverse but more disruptive. In such circumstances, organizations realize that IS incidents' timely detection and prevention in the future (what is more important) are not only possible but imperative. Any delay and only reactive actions to IS incidents put their assets under risk. A properly designed IS incident management system (ISIMS), operating as an integral part of the whole organization's governance system, reduces IS incidents' number and limits damage caused by them. To maximally automate IS incident management (ISIM) within one organization and to deepen its knowledge of IS level, this research proposes to unite together all advantages of a Security Intelligence Centre (SIC) and a Network Operations Centre (NOC) with their unique and joint toolkits and techniques in a unified Network SIC (NSIC). For this purpose the glossary of the research area was introduced, the taxonomy of IS threats, vulnerabilities, network attacks, and incidents was determined. Further, IS monitoring as one of the ISIM processes was described, the Security Information and Event Management (SIEM) systems' role in it and their evolution were shown. The transition from Security Operations Centres (SOCs) to SICs was followed up. At least, modern network environment's requirements for new protection solutions were formulated and it was proven that the NSIC proposed as a combination of a SIC and a NOC fully meets them. The NSIC's zone security infrastructure with corresponding IS controls is proposed. Its implementation description at the Moscow Engineering Physics Institute concludes the research at this stage. In addition, some proposals for the training of highly qualified personnel for NSICs were formulated. The creation of an innovative NSIC concept, its interpretation, construction and initial implementation through original research presented are its main results. They contribute substantially to the modern networks' security, as they extend the forefront of the SOCs and SICc used nowadays and generate significant new knowledge and understanding of network security requirements and solutions.
