What is CamFlow?

CamFlow stands for Cambridge information Flow architecture, the Cam is also the river that flows through Cambridge, UK.CamFlow is a Linux Security Modules (LSMs) designed to capture data provenance for the purpose of system audit.The provenance capture mechanism is highly configurable, and can fit the needs of many different type of applications.CamFlow can stack with existing security modules such as SELinux.Visit our project on github.

Research Project

CamFlow development started in 2014 at the University of Cambridge Opera Research Group (grant EPSRC EP/K011510/1). Further development has been supported by Harvard University’s Center for Research on Computation and Society as part of the Provenance@Harvard project (NSF grant SSI-1450277) and the University of Cambridge’s Digital Technology Group.Development is currently being supported at the University of Bristol Cyber Security Group.
