In computer networking: “Resilience is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation.”[1] Threats and challenges for services can range from simple misconfiguration over large scale natural disasters to targeted attacks.[2] As such, network resilience touches a very wide range of topics. In order to increase the resilience of a given communication network, the probable challenges and risks have to be identified and appropriate resilience metrics have to be defined for the service to be protected.[3]
These services include:
- supporting distributed processing
- supporting networked storage
- maintaining service of communication services such as
- access to applications and data as needed
Note that resilience is a superset of survivability.[4]
