Recovering from intrusions in distributed systems with DARE.

DARE is a system that recovers system integrity after intrusions that spread between machines in a distributed system. DARE extends the rollback-and-reexecute recovery model of Retro [14] to distributed system recovery by solving the following challenges: tracking dependencies across machines, repairing network connections, minimizing distributed repair, and dealing with long-running daemon processes. This paper describes an early prototype of DARE, presents some preliminary results, and discusses open problems.
