Abstract
National security in the era of globalization is no longer limited to military threats alone but also involves non-traditional issues such as climate change, cyber-attacks, pandemics, and food crises. This study aims to assess the level of knowledge, concerns, and perceptions of youth towards non-traditional security threats in Malaysia. A quantitative approach was used by distributing questionnaires to 300 university students from various academic backgrounds. The study instrument consisted of 23 items on a five-point Likert scale and was analyzed descriptively using SPSS software. The results of the study showed that all three main variables were at high levels, namely the level of knowledge (mean = 4.30), the level of concerns (mean = 4.20), and the perception of national security in the future (mean = 4.40). This finding reflects the high awareness among youth towards non-traditional security issues and their perception of the need for a more comprehensive security approach that focuses on human well-being. The study discussion also relates the findings to Barry Buzan's post-Cold War security theory and the concept of human security (UNDP, 1994), and emphasizes the importance of education, new media, and global experiences in shaping the security perceptions of the younger generation. This study recommends that security literacy among youth continue to be strengthened as a foundation for building sustainable and inclusive national resilience.
