Highly Available Intrusion-Tolerant Services with Proactive-Reactive Recovery
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...

State Transfer for Hypervisor-Based Proactive Recovery of Heterogeneous Replicated Services
Intrusion-tolerant replication enables the construction of systems that tolerate a finite number of malicious faults. An arbitrary number of faults can be tolerated during system ...

Proactive Service Migration for Long-Running Byzantine Fault Tolerant Systems
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 ...

Proactive Recovery in Distributed CORBA Applications
Unanticipated runtime events, such as faults, can lead to missed deadlines in real-time systems. While it is not always possible to know when a fault will occur, we can sometimes ...

How Resilient are Distributed f Fault/Intrusion-Tolerant Systems?
Fault-tolerant protocols, asynchronous and synchronous alike, make stationary fault assumptions: only a fraction f of the total n nodes may fail. Whilst a synchronous protocol is ...

Proactive resilience through architectural hybridization
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...

Proactive Resilience Revisited: The Delicate Balance Between Resisting Intrusions and Remaining Available
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...
