For Russia, the preservation of cultural heritage has become relevant in the context of the proxy war unleashed by the West against the Orthodox "Russian world". Cultural security is a state of public life in the cultural sphere, in which socializing institutions-agents ensure the implementation of their cultural and educational functions in society, in particular, in relation to the younger generation. The acceptance by young people of the standards and norms of traditional culture, synthesizing various types of subcultures, determines the state of cultural security for society and the country as a whole, and their denial causes a cultural danger. The system of cultural security protects the younger generation from any countercultural intervention. The institutional-socialization approach reveals the genesis of cultural security. All agents of socialization at their level form the foundations of the corresponding culture, promote its norms and values, socially approved and expected patterns of behavior for citizens of society.
