Purpose: This research investigates mobile security awareness among university students in Hong Kong, who increasingly rely on mobile devices for their daily activities and academic needs. This research seeks to inform targeted educational strategies and policies to enhance mobile security practices among young adults, particularly in regions similar to Hong Kong, where mobile usage is extensively integrated into everyday life. Design/methodology/approach: Utilizing an online survey, this research assessed the mobile security awareness of 407 university students from Hong Kong. The Mann-Whitney U-test and other statistical methods were employed to analyze differences in security awareness based on demographic factors such as IT background, gender, educational level and participation in mobile security courses. Findings: The research revealed a generally high level of mobile security awareness compared to similar research in other regions. It also highlighted that despite no significant difference in awareness between genders, students from IT-related fields or those who participated in mobile security courses exhibit higher awareness levels. These findings underscore the impact of focused education and training on enhancing mobile security awareness. Originality/value: This research contributes to the limited but growing body of literature on mobile security awareness from the end-user perspective, particularly among university students in the Asia Pacific region. It offers valuable insights for governments, educators and corporate policymakers worldwide, providing a basis for integrating mobile security education into broader academic and professional training programs.
