Challenge tracing and mitigation under partial information and uncertainty

The increasing dependency on communication infrastructures has introduced a significant vulnerability to our society. To increase their resilience and mitigate the impacts during failures, a variety of protection and restoration schemes have been developed to date. To most effectively protect these critical infrastructures, a deep operational knowledge about the mechanics and impacts of challenges on infrastructure assets and services is required, which is often only partially available and subject to varying degrees of uncertainty. This paper presents a computational methodology that is able to trace risk and challenge impacts within a networking system, therefore enabling an optimal allocation of protection resources for increased resilience.
