The paper is devoted to the definition of the special legal term «traditional Russian spiritual and moral values» / «traditional spiritual and moral values of the peoples of Russia». The relevance of the study is due to its role in the field of legal provision of information security (as the underlying system for ensuring relevant strategic national priorities). This interdisciplinary scientific research is carried out at the intersection of such legal sciences as information law, criminology, theory of forensic examinations (forensic expert science) and judicial speech. According to the results of the study, the authors conclude that the use of the category «morality» in normative acts does not mean at all that it is permissible to substitute ethical legal regulation. The analysis of the content of the term «traditional Russian spiritual and moral values» as a composite special legal term that generalizes and designates an extensive group of legal concepts, the development of an appropriate list and its consolidation in legal acts should be carried out based on the legal nature of the listed phenomena, and based on their comprehensive legal assessment (establishing the degree of compliance / non-compliance with the law, the presence/absence of public danger). Based on this approach, the authors propose their understanding of the term «traditional Russian spiritual and moral values» and list them. The authors propose an approach based on the ranking of values according to the degree of their social significance and compliance with the norms of law, expressed in the division of the entire set of traditional Russian spiritual and moral values into the so-called core and periphery. Nuclear values are the most significant, at the same time uniform for the whole society, supported, and stimulated by the existing system of law. Around the core of the essential values, there is a belt of secondary, that is, separate, less widespread traditions, values and foundations of individual social groups of our society.
