ABSTRACT:


Despite the pervasive nature of Internet censorship and the continuous evolution of how and where censorship is applied, measurements of censorship remain comparatively sparse.  Understanding the scope, scale, and evolution of Internet censorship requires global measurements, performed at regular intervals.  Unfortunately, the state of the art relies on techniques that, by and large, require users to directly participate in gathering these measurements, drastically limiting their coverage and inhibiting regular data collection.  To facilitate large-scale measurements that can fill this gap in understanding, we develop Iris, a scalable, accurate, and ethical method to measure global manipulation of DNS resolutions.  Iris reveals widespread DNS manipulation of many domain names; our finding both confirm anecdotal or limited results from previous work and reveal new patterns in DNS manipulation.


 


BIOGRAPHY:


Paul Pearce is a senior PhD student, University of California at Berkeley, advised by Vern Paxson and a member of the Center for Evidence-based Security Research (CESR).  His research brings empirical grounding to Internet security problems including censorship, cyber-crime, and advanced persistent threats (APTs).  Paul will be applying for tenure-track faculty positions this fall.
