The Impact of Passive DNS Collection on End-user Privacy
نویسندگان
چکیده
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 issue. From the technical point of view, DNS sensor architecture is analyzed and a statistical model is developed to describe the sensor’s ability to violate enduser privacy. To the other end, a review of various jurisdictions’ privacy legislation is presented and analyzed in the context of DNS as a system and pDNS as a collection mechanism. In general, we find that pDNS, properly configured, does not violate end-user privacy.

As the hidden backbone of today's Internet, the Domain Name System (DNS) provides name resolution service for almost every networked application. To exploit the rich DNS query information for traffic engineering or user behavior analysis, both passive capturing and active probing techniques have been proposed in recent years. Despite its full visibility of DNS behaviors, the passive capturing t...

متن کاملTowards Plugging Privacy Leaks in Domain Name System
Privacy leaks are an unfortunate and an integral part of the current Internet domain name resolution. Each DNS query generated by a user reveals – to one or more DNS servers – the origin and target of that query. Over time, a user’s browsing behavior might be exposed to entities with little or no trust. Current DNS privacy leaks stem from fundamental features of DNS and are not easily fixable b...

The Domain Name System (DNS) is the only globally deployed Internet service that provides user-friendly naming for Internet hosts. It was originally designed to return the same answer to any given query regardless of who may have issued the query, and thus all data in the DNS is assumed to be public. Such an assumption potentially conflicts with the privacy policies of private Internet hosts, p...
