<p>Computer networks are facing serious threats from the emergence of sophisticated new DGA bots. These DGA bots have their own dictionary, from which they concatenate words to dynamically generate domain names that are difficult to distinguish from human-generated domain names. In this letter, we propose an approach for identifying the callback communications of DGA bots based on relations among the words that constitute the character string of each domain name. Our evaluation indicates high performance, with a recall of 0.9977 and a precision of 0.9869.</p>

九州工業大学では、2014年9月に3キャンパス一斉にネットワーク環境を更新し、コアスイッチを40Gbps,戸畑および飯塚キャンパス間接続を40Gbpsとする全学セキュア・ネットワークシステムを導入した。全学セキュア・ネットワークシステムでは、大学とSINETへの接続境界点に学外公開IPへのアクセス制御を行うファイアーウォールを導入し、さらに各キャンパス毎に部局を収容可能なキャンパスファイアーウォールを導入した。また、各キャンパス内のコアスイッチは40Gbpsインタフェースを用いたバーチャルシャーシ構成による構築を行った。本報告では、これらのシステムを導入するにあたっての経緯や、事前調査、準備事項などについて述べる。

SSH Brute Force Attack Detection based on Flow Features Analysis

SATOH Akihiro, NAKAMURA Yutaka, IKENAGA Takeshi

IEICE technical report. Information networks ( The Institute of Electronics, Information and Communication Engineers ) 111 ( 346 ) 73 - 78 2011.12

Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

SSH brute force attack has become more seriously, so administrators are desired to implement its countermeasures. In the traditional ways, the SSH brute force attack has been detected by analyzing access logs and network traffic. However, the former way must check a huge quantity of the logs in all servers, and the latter cannot find victims of the attacks. To solve these problems, we propose SSH brute force attack detection based on the flow features analysis. As the experimental results, we showed to be able to identify the attacks and their victims.
