  Information security in the context of digital literacy is a digital skill
that enables safe and purposeful movement through virtual space. The age limit
and frequency of use of the Internet by young generations has been moved back a
year due to the COVID-19 pandemic, and the concern for information security of
young people is increasingly emphasized. If, and to what extent, knowledge of
the issue of identification and authentication affects the information security
of high school students aged 16 to 19 in the virtual space, the research
question addressed by the authors of this paper was to determine which student
behaviors pose a potential danger compromising their information security by
establishing a correlation between the variables that determine student
behavior and the variables used to examine their level of security in a virtual
environment. The research was conducted using a questionnaire on a sample of
high school students in the Republic of Croatia, the results of which showed
that some students practice behaviors that are potentially dangerous, make them
vulnerable and easy targets of cyber predators and attackers, which is why
there is cause for concern and a need for a additional education of children of
primary and secondary school age in the field of information security in the
form of the introduction of the subject Digital Literacy. Based on the results,
a model for assessing the level of digital literacy of adolescents that affect
information literacy can be designed, but also further related research in the
field of information literacy of children and youth can be conducted.
