Domain Name System (DNS) cache poisoning is a stepping stone towards advanced (cyber) attacks. DNS cache poisoning can be used to monitor users’ activities for censorship, to distribute malware and spam and to subvert correctness and availability of Internet clients and services. Currently, the DNS infrastructure relies on challengeresponse defences against attacks by (the common) off-path adve...

We study and document an important development in how attackers are using Internet resources: the creation of malicious DNS resolution paths. In this growing form of attack, victims are forced to use rogue DNS servers for all resolution. To document the rise of this “second secret authority” on the Internet, we studied instances of aberrant DNS resolution on a university campus. We found dozens...

This note reexamines Spector’s remarkable computational interpretation of full classical analysis. Spector’s interpretation makes use of a rather abstruse recursion schema, so-called bar recursion, used to interpret the double negation shift DNS. In this note bar recursion is presented as a generalisation of a simpler primitive recursive functional needed for the interpretation of a finite (int...

Remote-controlled malware, organized in so-called botnets, have emerged as one of the most prolific kinds of malicious software. Although numbers vary, in extreme cases such as Conficker, Bredolab and Mariposa, one botnet can span up to several million infected computers. This way, attackers draw substantial revenue by monetizing their bot-infected computers. This thesis encapsulates research o...

BACKGROUND Delayed neuropsychological sequelae (DNS) commonly occur after recovery from acute carbon monoxide (CO) poisoning. The preventive role and the indications for hyperbaric oxygen therapy in the acute setting are still controversial. Early identification of patients at risk in the Emergency Department might permit an improvement in quality of care. We conducted a retrospective study to ...

BACKGROUND Dental neglect has been found to be related to poor oral health, a tendency not to have had routine check-ups, and a longer period of time since the last dental appointment in samples of children and adults. The Dental Neglect Scale (DNS) has been found to be a valid measure of dental neglect in samples of children and adults, and may be valid for adolescents as well. We administered...

The Domain Name System (DNS) is one of the most fundamental components of the Internet. While glue is widely used and heavily relied on in DNS operations, there is little thinking about the necessity, complexity, and venerability of such prevalent configuration. This work is the first to provide extensive and systematic analysis of DNS glue. It discusses the availability implications of glue an...

This paper suggests an architecture of DNS service system for IPv6 mobile ad-hoc network connected to the Internet. The DNS resolution of DNS names of mobile nodes within mobile ad-hoc network is performed by multicast DNS and that of DNS names of nodes in the Internet is performed through DNS autoconfiguration of recursive DNS server. In the former, each mobile node plays a role of DNS name se...

In the Internet today, transfer rates are often limited by the bandwidth of a bottleneck link rather than the computing power available at the ends of the links. To address this problem, we have designed a novel link layer protocol that employs computation at the ends of the link to reduce bandwidth consumption across the link. Our scheme is motivated by the prevalence of repeated transfers of ...

This paper presents a novel competitive neural network learning approach to schedule requests to a cluster of Web servers. Traditionally, the scheduling algorithms for distributed systems are not applicable to control Web server clusters because different client domains have different Web traffic characteristics, Web workload is highly variable, and Web requests show a high degree of self-simil...
