While research into building robust and survivable networks has steadily intensified in recent years, similar efforts at the application level and below have focused primarily on attack discovery, ignoring the larger issue of how to gracefully recover from an intrusion at that level. The authors' paper attempts to bridge this inherent gap between theory and practice through the introduction of a new architectural technique, which they call rollback and huddle. Inspired by concepts made popular in the world of software debug, they propose the inclusion of extra on-chip hardware for the efficient storage and tracing of execution contexts.
