Methodological Approach to Creating a Cyber Defence Terminology System

The relevance of the study is determined by the recognised problem of heterogeneity and fragmentation of the cyber defence terminology in Ukraine. The lack of a unified, systematic terminology hinders effective interagency communication, the development of organizational and regulatory documentation, and operational coordination in countering cyber threats. The interdisciplinary nature of cyber defence, which encompasses national security, technology, law, and other fields, reinforces the need to unify the conceptual apparatus. Until now, this area has been studied selectively, without considering terminology as a coherent system. The purpose of this article is to highlight a methodological approach to creating a cyber defense terminology system. The methodological basis of the work is the theoretical foundations of terminology, in particular the distinction between the concepts of “terminology” (as a spontaneously formed set of terms) and “terminology system” (as a consciously ordered, coherent, and structured system of concepts based on a specific concept). An analysis of the current state of cyber defence in Ukraine shows that, in parallel with the development of the cyber defence system itself, cyber defence terminology is in the process of active formation and is undergoing stages of coordination and consolidation in scientific publications and legislative acts. A methodological approach is proposed, which consists in systematising and structuring the existing terminological fund to give it the characteristics of a coherent terminology system. Following this approach, key components have been identified that form the basis of the terminology system structure. The proposed model consists of six main subsystems (groups of terms): fundamental terms and concepts, cyber defence objects, cyber threats and vulnerabilities, the functioning of the cyber defence system and its components, cyber defence entities, as well as the legal and regulatory environment. It is noted that the cyber defence terminology system is synthetic in nature, integrating concepts in the fields of information technology, politics, economics, law, and defence. The proposed methodological approach has made it possible to create a comprehensive and structured terminology system that allows for the unambiguous classification of any term related to cyber defence. It is emphasised that this system is not static and will evolve along with changes in technologies and forms of cyber warfare. The practical value of the research results lies in the development of methodological recommendations for the further formation and improvement of terms based on the principles of consistency and unambiguous interpretation, which will contribute to ensuring effective communication and cooperation between different sectors and their operational coordination in the field of cyber defence.
