Abstract

Computer systems invest substantial resources in securing their service. Costs of failure prevention are balanced against those of detection and recovery, even though recovery mechanisms can cause greater degradations of services. Most computer users consider degradations of service to be insidious and injurious. Yet, service degradations commonly assist in both the prevention and the curtailment of failures. Their toleration enables service continuation following fault activation, during which degradations are monitored for symptoms of security breaches.
