Review of Cybersecurity Research Topics, Taxonomy and Challenges: Interdisciplinary Perspective

As cybersecurity is a growing field of science, there is not complete agreement across the scope of cybersecurity research topics. This paper proposes a grouping and classifications of cybersecurity researches to introduce an easily referenceable taxonomy of the cybersecurity research topics. A literature survey was conducted to collect published literature review papers about various cybersecurity researches during the past five years periods. Taxonomic analysis of 99 selected papers, which were grouped based on research topic similarities, produced sets of research categories. It categorized the cybersecurity research topics into 8 areas: (1) Applied cybersecurity, (2) Cybersecurity data science, (3) Cybersecurity education and training, (4) Cybersecurity incidents, (5) Cybersecurity management and policy, (6) Cybersecurity technology, (7) Human and social cybersecurity and (8) Theories in cybersecurity. Although cybersecurity grew out of the computer science field, this paper argues that its interdisciplinary nature (not only technical computer security, but also data, system/technology, and human/social) can attract researcher from various disciplines, such as management, policy, psychology, and so on, to contribute to cybersecurity advancement.
