This paper critically examines the relationship between cybersecurity and Copenhagen School’s widening security theory, with
the aim of assessing the possibility of applying this theoretical framework to the cyber realm. As cybersecurity is a relatively recent
addition to the security discourse, this research explores whether the Copenhagen School’s traditional framework, which was primarily
focused on securitisation processes in the five main sectors (military, political, economic, environmental, and societal), adequately
encompasses the unique aspects and dynamics of cyber domain. The research question is: Why the cybersecurity field can’t become a
separate constructivist sector? The study begins with a detailed overview of both cybersecurity landscape and Copenhagen School’s
fundamental principles to provide the context for a comparative analysis of the Copenhagen theory and contemporary cybersecurity
literature. In doing so, the research delves into the features of cybersecurity, with a focus on the evolving nature of cyber threats and
vulnerabilities. By performing a qualitative analysis of the existing literature, the paper assesses the limitations of integrating these two
concepts, ultimately concluding that cybersecurity lacks the distinct characteristics required to be considered a separate sector under the
Copenhagen School’s framework. The findings contribute to the ongoing discussions regarding the adaptation of traditional security
theories to address contemporary security challenges in the digital age.
