Retro-future: The Retrospective Future in the Internet

Project Summary

New network security events, from new zero-day attacks to insider threats, are only apparent after they have occurred. By definition, these events work in unexpected ways and only through hindsight may one learns what should have been collected and analyzed. To address these events, one either needs to predict the unexpected or travel back in time to replay the event. The premise of this project is to record enough network state to replay network security events and effectively travel back in time--in effect, to provide an Internet Digital Video Recorder (DVR).

The challenge in this effort is to provide Internet time-travel that is efficient, maximizing the effective history that is saved, to be cost-effective commodity hardware and software, and most importantly, to accommodate permission and privacy constraints that are necessary to deploy this system.

We expect that the resulting Internet DVR will help aid development and testing of network defenses.
