Seeing the actual condition of cyber terror that is happening these days, a situation on cyber security is being emerged as serious social issue beyond damage of an individual or enterprise. Above all, it is a situation of being difficult to guess damage, which may occur due to the leakage of personal information or to the leakage of secret information in enterprise or institution. To prevent this hacking damage, a system or solution is being developed diversely. However, it is difficult to perform security in the perfect form. The real situation is that requires the technology available for perceiving hacking incident in advance ahead of this, as well as the technology of detecting and coping with hacking incident in the shortest time in the aspect of range or scale in damage, which is created by hacking incident. The purpose of this study is to suggest solution on the whole defense of system through network by grasping the whole situation on this cyber terror. For the objective dubbed the internal data loss prevention, the mechanism is needed that can preferentially analyze and monitor suspicious behavior and also that can closely analyze data of being doubtful about malicious link. The aim is to propose mechanism available for preparing for potential attack by expanding the subjects of this analysis even into the internal network and separately-divided network without setting limits to the external network.
