Modern youth and the student community today play a key role in the development of social and social life. Due to the peculiarities of the university space, the student community is in constant interaction and communication, both in the framework of the educational process and events of various formats, and in social and everyday conditions. In the context of interactions, this social group, which is most at risk of spreading negative ideologies that threaten not only the personal security of everyone, but also peaceful coexistence in the conditions of a multinational society in Russia. In the absence of educational measures as a prevention, an unfavorable environment arises in which it is very easy to influence the thinking of young people, their involvement in nationalist movements, extremist activities, etc. Hence the concept of «youth extremism» appears, which is manifested in the views and behavior of young people based on the manifestation of aggression and non-acceptance of dissenters. The search for new technologies of psychological support that allow to form cultural tolerance, value orientations and prevent the spread of extremist ideologies becomes relevant. The authors consider a set of measures that contribute to the generalization, dissemination, as well as the introduction into the student environment of the best practices of spiritual and moral education, the development of interethnic and interreligious dialogue, and the prevention of negative ideologies. To implement these tasks, it is necessary to form a pool of specialists in the prevention of extremism in the student environment, hold seminars and meetings for vice-rectors of universities on security and educational work, as well as educational seminars for managers of student organizations. This will make it possible to form leadership student associations that broadcast the values of cultural tolerance to the youth environment.
