著者：Yaokai Feng, Yoshiaki Hori, Kouichi Sakurai, Jun-ichi Takeuchi題名：A Behavior-based Method for Detecting Distributed Scan Attacks in Darknets発表情報：Journal of Information Processing 巻: 21 号: 3 ページ: 527-538キーワード：概要：The technologies used by attackers in the Internet environment are becoming more and more sophisticated. Of the many kinds of attacks, distributed scan attacks have become one of the most serious problems. In this study, we propose a novel method based on normal behavior modes of traffic to detect distributed scan attacks in darknet environments. In our proposed method, all the possible destination TCP and UDP ports are monitored, and when a port is attacked by a distributed scan, an alert is given. Moreover, the alert can have several levels reflecting the relative scale of the attack. To accelerate learning and updating the normal behavior modes and to realize rapid detection, an index is introduced, which is proved to be very efficient. The efficiency of our proposal is verified using real darknet traffic data. Although our proposal focuses on darknets, the idea can also be applied to ordinary networks.抄録：The technologies used by attackers in the Internet environment are becoming more and more sophisticated.
