 note = {Domain Name System (DNS) is the most widely used protocol in the Internet for domain name Resolution. Since DNS provides many fundamental features Internet users would be strenuous without DNS. Recently, there are reports indicating malicious use of DNS to perform Botnet communications. However, since DNS traffic cannot be simply blocked due to its indispensability in the Internet. As such, we would like to propose a method on how to detect and control DNS based botnet communications by monitoring direct outbound DNS queries using OpenFlow Technology. We also constructed a local experimental network and evaluated the prototype system and confirmed that the proposed method worked as we expected. By using our proposed method, it is possible to detect and control some DNS based botnet based communications especially that uses direct outbound DNS traffic., Domain Name System (DNS) is the most widely used protocol in the Internet for domain name Resolution.
