| Abstract(in English) | We investigated the source IP address (SIP)- and query keyword (QK)- based entropy changes in the A and PTR resource records (RRs) based DNS query traffic between the DNS clients and the campus DNS server through January 1st to December 31st, 2008. The results are: (1) The both entropies simultaneously decrease when the targeted attack activity is high. (2) The SIP-based entropy increases while the QK-based one decreases, simultaneously, when the random attack activity is high. (3) The SIP-based entropy decreases while the QK-based one increases, at the same time, when the host search activity is high. Therefore, we can get important information for the security incidents by only observing the DNS query traffic. |
