Resilience Principles for the ICT Sector

Abstract

This chapter summarizes a set of abstract principles extracted from the literature pertaining to the resilience of systems in the ICT sector from which concrete solutions can be developed. Case studies are discussed that illustrate the validity and criticality of these principles. Also discussed is the interdependency among these principles that show that, in general, concrete solutions cannot be developed from principles individually but must be implemented in combination with other specific principles. A model of the phases of a disruption is shown and the applicability of these principles to these phases is discussed. Both single and multiple threat scenarios are discussed that reflect historical cases.
