Today s counter-terrorism policy means effectively excluding national threats, preventing them in advance, and responding appropriately to injustices. This means that the challenges faced must be solved by comprehen-sively operating all means of politics, diplomacy, economy, society, culture, military and science and technology in order to achieve national goals from various military and non-military threats at home and abroad. Especially in Korea, South Korea and North Korea are facing confrontation and are threatened by terrorism at the same time. Crimes such as espionage and terrorism transcend time and space, as well as being highly trained and mobile. It is also a representative national security risk crime by actors who comply with strict security rules. They are using advanced science and technology compared to the past, and they use cyber and terrorism, public rela-tions and education using SNS, and propaganda, as well as the use of communication between the Internet and smartphones. In this situation, legal evidence gathering by intelligence agencies or investigative agencies is increasingly difficult and inevitable. Moreover, despite the fact that information and investigative agencies have arrested security offenders in spite of poor conditions, it is now a reality that they do not admit their ability to testify or convict of illegally collected evidence. Therefore, the state and nature of security crimes, including terrorism, must be grasped and the nation should protect the lives and property of the people through proactive responses.
