Postmodernity as a concept of contemporary society together with technological progress and globalization caused changes in orientation of values as well as the transformation of individual and collective identity. Thus, increased vulnerability, both of individuals and society, caused the character of threats to national security. The aim of the article is to analyze the contemporary threats to national security as a phenomenon of a postmodern society, emphasizing the crisis of values as well as of the identity. Postmodern threats forced to revise traditional point of view on the concept of national security and demands to be based on comprehensive approach on the issues of security and defense. This article is an attempt to make an analysis on the topic of national security in an interdisciplinary context. After analyzing the actual threats to the security of the Republic of Lithuania, it was determined that the interaction of many of these threats with the crisis of values is evident. This allows to confirm the importance of further discussions and scientific research on the issues of values and identity in context of national security in postmodern society.
