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 twelve Ph.D. students, one masters student, and one postdoc.  Please contact Professor Nick Feamster if you are interested in opportunities in the lab.  We will post specific project opportunities soon.

Please also consider taking 8803 NGN (Next-Generation Networks) in Spring 2010, a new course on next-generation Internet architectures.

Network Neurality Tool NANO at ACM SIGCOMM CoNext

E-mail Print PDF

NANO ("Network Access Neutrality Observatory"), was presented at ACM SIGCOMM CoNext last Friday.

NANO detects whether a user's access ISP is discriminating against certain users, destinations or applications.  In contrast to existing tools, NANO relies primarily on data that is passively collected from user's machines.  To use NANO, simply download and install the NANO-Agent on your machine.  Currently, NANO-Agent runs only on Linux, but a Windows version will be coming shortly.

NANO is part of Google's Measurement Lab project.

For more information about NANO, please see the following:

Vytautas Valancius gave a great demo of the BGP Session Multiplexer ("BGP Mux") at the GENI Engineering Conference 6 in Salt Lake City, UT.  The BGP Mux is a system to provide interdomain routing connectivity to virtual networks and data center applications.

For more information about our GENI-funded project, please see our project web page at geni.net.

Here's a video summarizing Valas's demo:

OpenFlow Click Featured at Click Symposium

E-mail Print PDF

Yogesh Mundada gave a talk at the Click Symposium in Belgium last week on his new OpenFlow Click Element, which he developed with Rob Sherwood at Deutche Telekom Labs.

The OpenFlow Click element is a module for the Click modular router that can be controlled via a standard OpenFlow controller.  The element essentially turns a Click router into a software switch with flow table entries.  One of the most powerful aspects of this paradigm is that it allows hybrid packet and flow processing, as part of a paradigm we call Flowlets.

More details about OpenFlow Click element are available here:

NSF Awards $450k for Data Leak Prevention

E-mail Print PDF

The National Science Foundation has awarded Professor Feamster $450k over three years to develop techniques to control and prevent data leaks and the spread of malware in enterprise networks.

In Deloitte's recent Global Security Survey, nearly half of the companies surveyed reported some internal security breach; of those, about a third of breaches resulted from viruses or malware, and another third resulted from insider fraud.  The Pedigree project aims to develop mechanisms to control and prevent these data breaches in enterprise networks.  This growing problem begs the need for better techniques for controlling information flow in the network itself.

We are addressing several research challenges. First, we are exploring the appropriate granularity for tainting that preserves semantics without imposing unacceptable memory and performance overhead. Second, we are designing the system to minimize performance overhead on applications. Third, we are exploring translation mechanisms between host-based taints and network-based taints, so that taints carried in network traffic convey meaningful semantics without imposing prohibitive network overhead. The research will result in an information tracking and control system that is deployed in experimental settings (e.g., the Georgia Tech campus network) using the existing and forthcoming programmable switch implementations.

Our writeup of the system remonstration from SIGCOMM 2009 provides more details.  Details on the aware are available at the NSF Web site.
