An Event-based Data Model for Granular Information Flow Tracking.

We present a common data model for representing causal events across a wide range of platforms and granularities. The model was developed for attack provenance analysis under the DARPA Transparent Computing program. The unified model successfully expresses data provenance across a range of granularities (e.g., object or byte level) and platforms (e.g., Linux and Android, BSD, and Windows). This paper describes our experience developing the common data model, the lessons learned, and performance results in controlled lab experiments.
