The importance of these tools is growing in Slovakia and abroad, whether in the framework of pedagogical, work or other activities and activities related to communication between selected entities. The cyber environment is a three-dimensional computer world analogous to the Internet in which users move using virtual reality. This sphere is affected by many changes that can affect individuals, societies, and states. Nowadays, the more and more growing importance of cybersecurity as an integral part of the security sector. It is a complex area that includes technologies and processes designed to protect systems, networks, and data from cyber-attacks. An essential part of the analysis and assessment form a variety of communication tools. Long-term trends in the use of communication tools are to ensure secure communication and data transfer. Due to the current epidemiological situation associated with COVID-19, digital education is becoming a standard part of the educational process. However, in addition to digital education, benefits also come with multiple security risks that may negatively affect individuals or organizations. The main objective of this paper is to determine the level of cybersecurity selected communication tools through indicators. Based on established criteria, the level of security can be further differentiated. The primary motivation for processing the paper is the growing demand for communication tools and platforms enabling audio-visual communication of several participants, emphasing security aspects of communication in a virtual environment. © 2021, National Defence University - Carol I Printing House.
