The Internet is not a good place
Narseo Vallina-Rodriguez, Research Scientist, Networking and Security group, International Computer Science Institute (ICSI), Berkeley, USA
The Internet is a messy, complex landscape. Middleboxes such as DNS resolvers, UPnP home gateways, and in-path proxies placed in the IP core of the operators’ networks can significantly
impair a user’s access despite being designed for the contrary. In addition, they tend to modify traffic and some even have 5 y.o. vulnerabilities suggesting the presence of other underlying inefficiencies and bugs.
In this talk, I will describe some of our experiences and efforts finding to map out the terra incognita of the Internet, specifically mobile networks. In our endeavor, we use Netalyzr, a widely deployed end-host measurement tool developed at ICSI. In this talk, we will describe how we extended and adapted the tool to the mobile context, highlighting some of the challenges we are facing in its development, deployment, user incentivization and data analysis. More in detail, I will talk about the impact of business relationships on users’ quality of service, middleboxes behavior, and how handset misconfigurations and customized vendor and operator Android images impact on the certificate Root Stores.
