Statistical Study of Unusual DNS Query Traffic

by Dennis Arturo, Yasuo Musashi, Hirofumi Nagatomi, Kenichi Sugitani
"... We statistically investigated on the unusual big DNS resolution traffic toward the top domain DNS server from a university local campus network in April 11th, 2006. The following results are obtained: (1) In April 11th, the DNS query traffic includes a lot of fully qualified domain names (FQDNs) of ..."

Threats of Unusual DNS Query Traffic from NIS Clients

by Dennis A. Ludeña Romaña, Hirofumi Nagatomi, Yasuo Musashi, Kenichi Sugitani
"... Abstract We statistically investigated on unusual DNS query traffic from the several Linux PC servers employing network information system (NIS) as their authentication in the campus network of a university. The following re-sults are obtained: (1) The DNS query traffic includes specific keywords of ..."

CoDNS: Improving DNS Performance and Reliability via Cooperative Lookups

by Kyoungsoo Park, Vivek S. Pai, Larry Peterson, Zhe Wang - In Proceedings of the Sixth Symposium on Operating Systems Design and Implementation (OSDI , 2004
"... The Domain Name System (DNS) is a ubiquitous part of everyday computing, translating human-friendly machine names to numeric IP addresses. Most DNS research has focused on server-side infrastructure, with the assumption that the aggressive caching and redundancy on the client side are sufficient. Ho ..."

. It uses a locality and proximity-aware design to distribute DNS requests, and achieves low-latency, low-overhead name resolution, even in the presence of local DNS nameserver delay/failure. Using live traffic, we show that CoDNS reduces average lookup latency by 27-82%, greatly reduces slow lookups

DNS resolution with renewal using piggyback

by Beakcheol Jang, Dongman Lee, Kilnam Chon, Hyunchul Kim - In Proceedings of the Twelfth International World Wide Web Conference (Poster , 2003
"... Abstract: Domain Name System (DNS) is a primary identification mechanism for Internet applications. However, DNS resolutions often take an unbearably long time, and this could seriously im-pair the consistency of the service quality of Internet applications based on DNS such as World-Wide Web. Sever ..."
Abstract - Cited by 7 (0 self) - Add to MetaCart
. Several approaches re-duce DNS resolution time by proactively refreshing expired cached records or prefetching available records beforehand, but these ap-proaches have an inherent problem in that they cause additional DNS traffic. In this paper, we propose a DNS resolution time re-duction scheme, named

Detection of NS Resource Record DNS Resolution Traffic, Host Search, and SSH Dictionary Attack Activities

by Kazuya Takemori , Dennis Arturo , Ludeña Romaña , Shinichiro Kubota , Kenichi Sugitani , Yasuo Musashi
"... Abstract: We carried out an entropy study on the DNS query traffic from the Internet to the top domain DNS server in a university campus network through January 1st to March 31st, 2009. The obtained results are: (1) We observed a difference for the entropy changes among the total-, the A-, and the ..."

these results,we can detect the unusual inbound NS RR based DNS traffic and the outbound SSH dictionary attacks by only watching DNS query traffic from the Internet.

Analysis of IPv6 Based DNS Query Traffic

by Ipv Ipv, Hirofumi Nagatomi, Dennis Artona
"... Abstract: We investigated statistically on the IPv6 source IP address-based DNS query traffic a university campus network through January 1st to December 31st, 2005. The results are summarized, as follows: (1) Several security incidents in the IPv6-based DNS query traffic can be observed in or synch ..."

in or synchronized with the IPv4-based DNS query one like a mass mailing worm (MMW)- or spamming from the bot worm (BW)-infected PC terminals, and (2) we can also find a suspicious IPv6 based PTR resource record (RR) based DNS query traffic like a typical reverse domain resolution access in preparation for the next

The Use of DNS Resource Records

by Simar Preet Singh
"... Abstract: DNS (Domain Name System) is the service which translates between Internet names and Internet addresses. Internet names are the names which we use to refer to hosts on the Internet, such as www.websites.net. Internet addresses are the numbers which routers use to move traffic across the ..."

Detecting Malware Domains at the Upper DNS Hierarchy Abstract

by Manos Antonakakis, Roberto Perdisci, Wenke Lee, Nikolaos Vasiloglou Ii, David Dagon
"... In recent years Internet miscreants have been leveraging the DNS to build malicious network infrastructures for malware command and control. In this paper we propose a novel detection system called Kopis for detecting malware-related domain names. Kopis passively monitors DNS traffic at the upper le ..."

Compared to previous DNS reputation systems such as Notos [3] and Exposure [4], which rely on monitoring traffic from local recursive DNS servers, Kopis offers a new vantage
