The national document flow in the area of information safety is analyzed based on the Russian Science Citation Index database for 1993–2017. Its volume makes over 18,000 entries including up to 59% articles and conference proceeding (28%). The flow dynamics demonstrates its annual growth – it is ahead of other science information flows in the number of documents. The dispersion of publications in periodicals in 2016 is characterized; the dependence of the information flow completeness from the number of sources is considered. The findings of microflow study have proved the provision of S. Bradford’s law of the periodicals division into three zones. The “core” comprises 52 journals, primarily in the related sectors rather than those specializing in the mentioned area which evidences on the vibrant interdisciplinary character of the problem. The authors characterize information significance of the most productive journals using such indicators as the 2-year impact-factor and the number of article loads. It was found that the impact-factor as a criteria of journal influence was in the range 0.040–1.435, while the number of loads was from 252 to 56,041. The accessibility of the “core” journals in the RSCI as related to the availability of full texts and the open access and their coverage by RSCI, WoS and Scopus databases are discussed.
