Abstract:
In the current situation where the damage caused by targeted attacks is becoming more serious, it is important to minimize their damage through early detection and response. However, there are problems with speed and coverage in the investigation methods based on suspicious IP addresses and Indicators of Compromises(IoC), which are common responses. Therefore, we propose a security risk assessment system based on the similarity to victims. This system uses elements other than IP addresses and IoCs, such as used software and logged-in users, and assesses the possibility of intrusion based on similarity to the victim. In this paper, we show the effectiveness and potential of this system by evaluating it using a prototype.
