Abstract

The sovereign state has the right to engage in self-defense or war with the approval of the Security Council when itreceives an invasion of territory from a foreign country. War is conducted under the principle of the necessity andproportionality of self-defense. In case of cyber attack, proportional countermeasure must be made through attack means andeffect analysis, and cyber weapons need to be classified for this purpose. Therefore, this study aims to provide a rationaland legitimate response according to the necessity and proportionality of the self - defense right by suggesting definition andclassification criteria of cyber weapons. In this study, cyber weapons were defined as "means of collecting, attacking, andprotecting information using cyber technology in the cyber space according to military objectives. Based on existing weaponsystems and public cyber weapons cases, cyber weapons were classified as ① cyber weapons for information gathering, ②cyber weapons for attack, and ③ cyber weapons for protection. We suggest the considerations for applying the proportionalresponse according to this functional classification. In order to guarantee the principle of proportionality to cyber attacks inthe future, the classification study based on the cyber weapon effect should be conducted. This study has conducted anexploratory study on the classification of cyber clusters which constitutes one axis of the proportionality principle.
