| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, cyber attacks become more sophisticated and cause serious damage. Especially in targeted attacks, it is difficult to prevent intrusion of attacks, and the recent countermeasures focus on mitigation of damages by early detection and quick response against attacks. Previously, we proposed an incident response support system that recommends countermeasures of targeted attacks to network administrators. However, the system focuses on isolating the infected host and it's near hosts, and the infection possibility of other hosts is not considered. Therefore, we propose an Assessment System for Residual Risks of Information Leakage in Incident Countermeasures, and this paper discusses the initial study of the proposed system. The proposed system evaluates the residual risk of information leakage based on the risk of malware infection of all hosts in the network by a series of attacks and the importance of resources accessible from each host. We can select and take countermeasures in terms of residual risks by the proposed system. |
