Situational awareness for hybrid warfare: Risk measurement between cyber warfare and nuclear warfare

North Korea's Kim Jong Eun regime has conducted nuclear tests and missile provocations despite international agendas. In North Korea, these conventional provocations are being carried out in parallel with cyber attacks. In particular, North Korea's cyber attacks have been mostly concentrated on South Korea. Recently, there has been a suspicion that Ransomware such as WannaCry is behind the North Korean regime, and the cyber provocation of the North Korean regime is expanding all over the world. North Korea's cyber attacks have characteristic after nuclear or missile experiments. However, many countries' security policies and studies are proceeding by separating nuclear threat and cyber threat into separate problems. As can be seen in Georgia, Russia embodies the first hybrid battlefield to combine conventional and cyber weapons. If North Korea continues to invest in increasing nuclear power and cyber power, it may construct a new battlefield combining nuclear warfare and cyber warfare. This study proposes a hybrid type situational awareness model based on the FAIR (Fault Analysis of Information Risk) model for multiple threats in Northeast Asia.
