Network Operations and Internet Security Lab

Welcome

The GTNoise lab focuses on developing new algorithms, protocols, and systems for the current and next-generation Internet, with a specific focus on network operations and security.

Our work ranges from fighting the Internet's cybercriminals (spam, phishing, etc.) to improving Internet availability to making networks easier to diagnose and operate.  Please click on the projects page to find out more.

The lab has nine Ph.D. students, one research scientist, and one postdoc.  We also host occasional visitors from universities around the world (most recently from Italy and India).

Please contact Professor Nick Feamster if you are interested in opportunities in the lab.

Please also consider taking CS 6250 (Computer Networking) in Fall 2012, a project-based course that won the SIGCOMM Education Workshop Best Paper Award in August 2011 for innovations in helping students learn architectural concepts with hands-on projects and assignments.

Bobble "Filter Bubble" Tool Released

E-mail Print PDF

We have released Bobble, a Chrome extension to help users visualize how their search results are being personalized.  The filter bubble is a concept developed by Internet activist Eli Pariser to describe a phenomenon where websites use algorithms to predict what information a user may like to see based on the user's location, search history, etc. As a result, a website may only show information which agrees with the user's viewpoints. One such example is Google's personalized search results. To "pop" the bubbles created by Google search (also called de-personalization), we have developed Bobble, a Chrome extension that uses hundreds of nodes to distribute a user's Google search queries worldwide each time the user performs a Google search.
