It can be said that the COVID-19 pandemic has an important role in the spread of personal and institutional use of digital communication channels. These developments, which further increase the importance of digital data security, can also be evaluated in terms of messaging applications, which is one of the most used digital communication channels. Digital data security, which has become more and more important with the spread of communication technologies, covers not only privacy and security problems arising from personal use, but also privacy and security problems arising from corporate use, which can also have national security characteristics. These problems may include political, economic, and military dimensions. In this study, messaging applications as digital communication channels are discussed in the context of digital data security strategies. The study aims to question the contributions of nationalization in digital communication channels to data security in messaging applications.
