The article continues the study “Modeling and Assessment of National Power of Different Countries all over the World” dedicated to the calculation of national power indicator. It is currently the most informative and popular indicator in the world that integrally characterizes the aggregate potential of a particular country and at the same time allows comparing the level of its power and socio-economic development with other countries. The research results were published in the article “Modeling and Assessment of National Power of Different Countries all over the World”. If national power of the state, in fact, determines its potential capabilities and gross indicators are mainly used for the calculation, then national security indicators are calculated on the basis of normalized values (as a rule, per capita) and indicate the level of development of one or another component of the social-ecological-economic system of the country, as well as the efficiency of using the existing potential. In this article we will calculate national security indicators of UN member states using the methods of multivariate statistical analysis. Moreover, we will estimate threshold values for all national security factors considered herein. The last part of the paper will contain a forecast of national security for the medium term.
