Abstract: Comprehensive comparative analyses of national cyber security strategies (NCSSs) have thus far been limited or complicated by the unique nature of cybersecurity, which combines various areas such as technology, industry, economy, and defense in a complex manner. This study aims to characterize the NCSSs of major countries, quantitatively considering the time series, and identify further cybersecurity agendas for the benefit of NCSS revision in South Korea, by applying topic modelling to the analysis of eight NCSSs from the US, UK, Japan, and EU. As a result, fifteen agendas were identified and grouped into four sectors. We determined from the agenda distribution that the approach of each country to cybersecurity was different. In addition, additional agendas worthy of consideration for future NCSS revisions in South Korea were proposed, based on a comparison of the 15 aforementioned agendas with those of South Korea. This study is significant for cybersecurity policy in terms of enabling quantitative analysis in a single framework via latent dirichlet allocation (LDA) topic modelling, and deriving further cybersecurity agendas for future NCSS revisions in South Korea.

Keywords: Cybersecurity policy; national cyber security strategy (NCSS); policy analysis; quantitative analysis
