Among various social media platforms, the concept of all users’ openness and accessibility of information is becoming even more lifelike. Social networks afford to receive the freshest news, communicate with various interesting people, regardless of their location and residence, contribute to changing the interaction between people, and so on. This article presents the standard principle of content analysis of the publications indexed in the Scopus and WoS databases and provides the analysis of 67 high-rating publications. The result of the analysis allows for the conclusion that most social network researchers use readily available methods for classifying the threats to information security violations, which cannot be considered specifically suitable for the analysis of social networks since they do not reflect the characteristic features of research in this area. This paper proposes a different approach to the clustering of implemented threats to the information security of social networks. An analysis of the currently existing threats and vulnerabilities in the information security of social networks indicates that the achievement of the goals and objectives of information protection, as well as ensuring the maximum level of security, requires the integrated use of available methods and means of protection.
