Nick Feamster Research: Network security and operations –Helping network operators run the network better –Helping users help themselves Lab meetings: Tuesdays at 12 p.m. (free lunch) –Informal seminar. Papers on wireless, virtualization, etc. –Come visit us or me if you want to learn more Teaching 7001 this fall. Willing to supervise 8903s/mini-projects Klaus 3348 Network Operations and Internet Security Lab

Research Focus: Network Security & Operations Goal: Improve network reliability and availability in the face of both accidental and malicious faults Areas –Reliability: fast recovery from failures –Management: fault diagnosis, provisioning –Security and trust: spam filtering, phishing –Anti-censorship: e.g., defeating the great firewall of China –Economics: improving the efficiency of the Internets connectivity markets

Research Approach Interdisciplinary: Learn and apply variety of domains –Machine learning, signal processing, algorithms, data mining –Collaboration with Profs. Gray, Lee, Vempala, Vazirani, Xu Practical: Build working systems that people use –Problem driven: network management, anti-censorship, fighting spam, etc. –Implementation and real-world deployment of working systems Relevant: Interaction/funding with research & industry –Spam: Cisco/Ironport, Yahoo!, McAfee, Verisign –Management/Diagnosis: AOL, Thomson, Georgia Tech Campus –Availability/Economics: ONR, NSF, GENI –Publication: SIGCOMM, SIGMETRICS, IMC, CCS, USENIX Security From practice, to theory, to practice. 1. Attack practical networking problems with principled methods. 2. Transfer the solutions to the real world with working systems.

New Research: Utility Networking Building and using communications networks should be as easy as plugging a device into the power outlet. –User-proof networking: Designing devices and protocols for home networks. Users plug in devices and the network just works. –Elastic networking: Designing networks so that they can be rapidly provisioned when demands fluctuate. (Think: Cloud computing, but for networks instead of servers.) Exciting times: the equivalent of an open source movement in network devices is happening now. Come talk to me to learn more!
