An Agenda for Empirical Cyber Crime Research
Speaker: Stefan Savage, Director of the Collaborative Center for Internet Epidemiology and Defenses (CCIED) and Associate Professor, UCSD

Video View the Video

Computer security is a field that is fundamentally co-dependent—driven to respond by the actions of adversaries. This dance fuels both the research community and a multi-billion-dollar computer security industry. However, to date most efforts have focused on the technical components of this battle: identifying new vulnerabilities, exploits, and attacks, building and deploying new defenses, and so on. In this talk, I will argue for a complementary research agenda based on understanding the business models that drive today's Internet attacks, deconstructing the underlying value chain for attackers and ultimately using this information to better focus on security interventions. I will provide a rough sketch of the modern cyber-criminal ecosystem, describe its dependencies, and highlight some of the key open questions that motivate our focus. Using a range of activities, including our own completed studies, work in progress, and work in development, I'll illustrate how many of these questions can be tackled empirically. Along the way, I'll discuss the real and significant challenges in conducting this sort of research and how we address these issues in practice. Finally, I'll play pundit and predict where the greatest opportunities for impact are likely to be found.

Stefan Savage is a professor of Computer Science and Engineering at the University of California, San Diego. He received his Ph.D. in Computer Science and Engineering from the University of Washington and a B.S. in Applied History from Carnegie Mellon University. Savage's research interests lie at the intersection of distributed systems, networking, and computer security, with a current focus on embedded security and the economics of cybercrime. He currently serves as director of UCSD's Center for Network Systems (CNS) and as co-director for the Cooperative Center for Internet Epidemiology and Defenses (CCIED), a joint effort between UCSD and the International Computer Science Institute. Savage is a fairly down-to-earth guy and only writes about himself in the third person when asked.

Helping Humanity with Phones and Clouds
Matthew Faulkner, graduate student in Computer Science at Caltech, and Michael Olson, graduate student in Computer Science at Caltech

Meeting global challenges requires informed decisions. Often, these decisions require gathering data across geographic regions over time, detecting patterns that indicate significant events, formulating best responses to an event, then executing and monitoring those responses. Such decisions are made when deploying first responses to earthquakes, providing health care to people in under-served remote areas, and monitoring natural resources. Smart phones and tablets enable acquisition of data from almost anywhere on the globe. Cloud computing, likewise, enables aggregation and analysis from anywhere on the globe. This talk describes research on applications combining phones and clouds for earthquake detection and rural health care. We show how coupling community sensing and citizen participation to phones and clouds could radically improve the way that technology serves humanity, including the less fortunate, around the globe.

Matthew Faulkner is a graduate student in Computer Science at Caltech. He received an S.B (2008) and an M.Eng. (2009) in Computer Science from MIT. His research interests are in machine learning, distributed systems, and sensor networks.

Michael Olson is a graduate student in Computer Science at Caltech. He received a B.S. (2004) in Computer Science from Carnegie Mellon. His research interests are in distributed systems, sensor networks, and event processing.
