Proactive fault handling combines prevention and repair actions with failure prediction techniques. We extend the standard availability formula by five key measures: (1) precisio...
In the past, some research has been done on how to use proactive recovery to build intrusion-tolerant replicated systems that are resilient to any number of faults, as long as reco...

In a recent paper, we presented proactive resilience as a new approach to proactive recovery, based on architectural hybridization. We showed that, with appropriate assumptions ab...

In this paper, we describe a proactive recovery scheme based on service migration for long-running Byzantine fault tolerant systems. Proactive recovery is an essential method for ...
Abstract The uncontrolled propagation of faults due to malicious intrusion can severely decrease system performance and survivability. Our goal is to employ available information a...
