Context: With the rapid development of the Fourth Industrial Revolution, legal violations in cyberspace are increasing, posing threats to information security and social order. Students majoring in National Defense and Security Education (NDSE) at Ho Chi Minh City University of Education (HCMUE) are required not only to have a clear understanding of cyber laws to protect themselves but also to possess sufficient knowledge to educate and raise awareness within the broader community. Findings: By employing practical survey methods, interviews, and observation, this study analyzes and evaluates the current awareness levels of NDSE students at HCMUE regarding cyber law violations. The survey results show that although students are aware of the illegality of such behaviors, they still engage in them due to gaps in their understanding of legal regulations and consequences. Discussion: Based on the findings, the study proposes several measures to enhance students' awareness of common cyber law violations, including promoting legal education on cyber violations; strengthening monitoring and enforcement of cyber regulations within the university; intensifying media coverage of cyber violations through social platforms; and fostering critical thinking and responsible information verification skills. Enhancing awareness not only encourages students to comply with the law but also contributes to building a safe and healthy online environment in line with national security demands in the digital era.
