Survivability

A New Extended Evolutionary Game Theory Approach to Strategic Information Warfare Research

ABSTRACT

The extended evolutionary game theory (EEGT) extends traditional evolutionary game theory (EGT) with survival analysis and agreement algorithms. Survival analysis, a branch of modern biostatistics, is adopted to model the consequences of the so-termed UUUR (Uncertain, latent, Unobserved or Unobservable Risks) events. Agreement algorithms can be the Agreement algorithms from the traditional fault-tolerant distributed computing or any problem-specific (user-defined) algorithms (constraints) that allow game players to dynamically check and 'vote' for a possible consensus. The EEGT was initiated in the study of reliability and survivability of distributed computer networks and is particularly suitable for addressing critical issues such as dynamic uncertainty, vulnerability, frailty, and deception, which are often associated with distributed systems under stressed environments where the occurrence of UUUR events is the norm. Strategic information warfare (SIW) clearly falls within the scope of such systems. In this paper, the EEGT is introduced to the modelling of SIW from a three-layer (tactical, strategic and operational levels) perspective.  When applied to SIW, a tertiary extension to EEGT with hedging principle is necessary at the operational level, similar to the application of the EEGT to survivability analysis.

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.
