The Impact of Passive DNS Collection on End-user Privacy
There are two distinct problems in determining the impact of passive DNS (pDNS) on end-user privacy. One is whether or not pDNS would allow the observer to reconstruct an individual end-user’s DNS behavior. The other is if DNS behavior constitutes personally identifiable information (PII) or is otherwise legally protected. This paper develops a framework to discuss both aspects of the privacy i...

متن کاملPassive Monitoring of DNS Anomalies
We collected DNS responses at the University of Auckland Internet gateway in an SQL database, and analyzed them to detect unusual behaviour. Our DNS response data have included typo squatter domains, fast flux domains and domains being (ab)used by spammers. We observe that current attempts to reduce spam have greatly increased the number of A records being resolved. We also observe that the dat...
متن کاملBotnet Detection Using Passive DNS
The Domain Name System (DNS) is a distributed naming system fundamental for the normal operation of the Internet. It provides a mapping between user-friendly domain names and IP addresses. Cyber criminals use the flexibility provided by the DNS to deploy certain techniques that allow them to hide the Command and Control (CnC) servers used to manage their botnets and frustrate the detection effo...
متن کاملT-DNS: Connection-Oriented DNS to Improve Privacy and Security
This paper explores connection-oriented DNS to improve DNS security and privacy. DNS is the canonical example of a connectionless, single packet, request/response protocol, with UDP as its dominant transport. Yet DNS today is challenged by eavesdropping that compromises privacy, sourceaddress spoofing that results in denial-of-service (DoS) attacks on the server and third parties, injection att...
