Social networks play an important role in the socio-economic life of countries, including Vietnam. The objective of the study is to assess factors affecting cybersecurity in Vietnam. Based on the results of a survey of 160 young people using social networks and analysis using SPSS software, the study results show that government policies and community awareness have a positive impact on cybersecurity. However, there is no relationship between cybersecurity enforcement and monitoring, habits, and culture when using social networks on cybersecurity. On the contrary, the study also affirms that the living environment has a positive impact on cybersecurity.
