Networking and Security

The Networking and Security Group focuses on understanding the behavior and use of today's Internet and exploring new technology and designs for tomorrow's Internet. Researchers' interests range from fundamental architectural questions, new forwarding mechanisms and novel management approaches to network defenses, cybercrime, troubleshooting, measurement, and characterization. Security research includes development and maintenance of the open-source Zeek network monitoring system, along with studying censorship, abusive surveillance, mobile device privacy, and the TLS ecosystem. The Group has strong ties to UC Berkeley, with two of its members holding joint appointments; with Stanford University; and with a number of start-ups — particularly Corelight, which builds industrial-strength Zeek-based systems — and various Internet companies and services. Group members have also been active in professional organizations and events, such as ACM SIGCOMM, IMC, HotNets, USENIX Security, FOCI, and IEEE Security and Privacy.

Professor Mark Allman leads the Networking and Security Group.

Agent Based Modeling at the Boundary of Law and Software

ICSI researchers are studying how agent-based models (ABMs) of social contexts can improve the design and regulation of accountable software systems. Agent-based modeling is a social scientific research method that involves bottom-up modeling of complex systems and computationally determining their emergent properties by running simulations. The ICSI researchers are using ABMs to model elements of the social and regulatory environment in which a software system operates.

PacketLab: A Universal Measurement Endpoint Interface

The right vantage point is critical to the success of any active measurement. However, most research groups cannot afford to design, deploy, and maintain their own network of measurement endpoints, and thus rely measurement infrastructure shared by others. Unfortunately, the mechanism by which we share access to measurement endpoints today is not frictionless; indeed, issues of compatibility, trust, and a lack of incentives get in the way of efficiently sharing measurement infrastructure.

Rethinking Home Networking for the Ultrabroadband Era

People generally center their lives around their residence. This center of gravity is where we can be contacted, store our things, do our homework, play games, meet after disparate activities, eat our meals, and so on. Our digital lives are, however, not organized around such a hub. Rather, we use a myriad of services to communicate with one another, store pictures, work on documents, share videos, keep our music, deal with calendars, etc. In this arrangement we are the hub. Our content and information comes to us from a range of places to wherever we happen to be at the moment.
