A Security Analysis of the Combex
DarpaBrowser Architecture
by David Wagner and Dean Tribble
This Darpa sponsored review of the Combex DarpaBrowser architecture concludes by saying:
We wish to emphasize that the web browser exercise was a very difficult problem.� It is at or beyond the state of the art in security, and solving it seems to require invention of new technology.� If anything, the exercise seems to have been designed to answer the question: Where are the borders of what is achievable?� The E capability architecture seems to be a promising way to stretch those borders beyond what was previously achievable, by making it easier to build security boundaries between mutually distrusting software components.� In this sense, the experiment seems to be a real success.� Many open questions remain, but we feel that the E capability architecture is a promising direction in computer security research and we hope it receives further attention.
