13 Resilience Resilient Networks Resilience Definition provide and maintain acceptable service in the face of faults and challenges to normal operation Challenges faults unintentional misconfiguration or operational mistakes large scale natural disasters malicious attacks from intelligent adversaries environmental challenges unusual but legitimate traffic service failure at a lower level 22 July 2009 GpENI and ResiliNets 13

14 Scope of Resilience Relationship to Other Disciplines Survivability many targetted failures Fault Tolerance (few random) Challenge Tolerance Traffic Tolerance Disruption Tolerance environmental delay energy mobility connectivity Robustness Complexity Trustworthiness Dependability reliability maintainability safety availability integrity confidentiality Security nonrepudiability AAA auditability authorisability authenticity legitimate flash crowd attack DDoS Performability QoS measures 22 July 2009 GpENI and ResiliNets 14
