Diversity

Survivability in Cyberspace Using Diverse Replicas: A Game-Theoretic Approach

ABSTRACT

Survivability represents the quantified ability of a system, subsystem, equipment, process or procedure to function continually during and after a disturbance. Almost invariably, replication of a subsystem or procedure is necessary to meet a system’s survivability requirements. Diversity will prevent the same fault or attack from damaging all the replicas so that they can continue the mission. This research shows that the more dangerous vulnerabilities (that is, those that affect more replicas) in a system are sometimes less likely to be exploited. This work uses the mathematical framework of game theory to show the significance of replica diversity for mission survival in cyberspace.
