Purpose: Korean university students have a special interest in security issues, understand the importance of Northeast Asian and foreign situations and national security, and have a sense of responsibility. This is because Korean university students recognized the importance of security through service in the military, and they are aware of security threats and espionage activities even after being discharged. Therefore, by publishing this thesis in English, we intend to contribute to prosperity and peace by sharing information on the security awareness of Korean university students with researchers around the world.
 Method: Frequency analysis was conducted to identify general characteristics using the SPSS/PC+23.0 program, and Cronbach’s α coefficient was calculated to verify the reliability of the questionnaire. In addition, Factor Analysis, Correlation Analysis, and Simple Linear Regression Analysis were conducted on Korean university students’ perception of counterespionage activities, security reporting methods, threats from neighboring countries, and the role of the government.
 Results: ‘Threat and awareness’ factors were extracted for Korean university students’ perception of counterintelligence activities, and 'public factors' and 'personal factors' were extracted for security reporting methods. As major national threats, 'dictatorship' and 'liberal democracy' were classified and extracted, and the government's role was extracted as requiring 'joint response'. Perception of counterintelligence activities correlated with security reporting methods, threats from neighboring countries, and the role of the government. There was also a significant correlation between security reporting methods, threats from neighboring countries, and the role of the government. As a result of simple linear regression analysis, it was found that counterintelligence activity perception affects the method of reporting security, threats from neighboring countries, and the role of the government.
 Conclusion: Korean university students are aware of threats from neighboring countries, and Korea’s military service system is important for raising awareness of the importance of national security through mandatory service in the army and training in the reserves. Korean university students have negative perceptions of the dictatorships of neighboring countries North Korea and China, are aware of China's espionage and cyber psychological warfare, and are aware of the reality by watching TV broadcasts featuring North Korean defectors, and are fully aware of the threat. In response to these threats, Korean university students aspire for stability and prosperity in Northeast Asia through joint responses by government departments.
