Abstract: This paper examines the level of cybersecurity knowledge among high school students using a digital quiz. The aim was to identify areas of strong awareness as well as those requiring additional education. A quantitative approach was employed, based on a structured digital quiz conducted among 268 students from three grammar schools, with data analyzed using descriptive and correlational statistics. The results indicate a high overall accuracy rate (87.69%), with the highest scores in topics related to password security and digital footprints, and the lowest in identifying personal data, ransomware, and two-factor authentication (2FA). No significant correlations were found between accuracy and completion time, nor between device type and performance. The study highlights the importance of structured cybersecurity education in secondary schools.
