The pervasive interconnection of systems throughout the world has given computer services
a significant socioeconomic value that both accidental faults and malicious activity can …

Intrusion Tolerance has become a reference paradigm for dealing with intrusions and
accidental faults, achieving security and dependability in an automatic way, much along the …

While providing some resistance against cyberattacks, current approaches to securing
networked and distributed information systems are mainly concerned with static prevention …

Applications that are part of a mission‐critical information system need to maintain a usable
level of key services through ongoing cyber‐attacks. In addition to the well‐publicized denial …

MAFTIA was a three-year European research project that explored the use of fault-tolerance
techniques to build intrusion-tolerant systems. The MAFTIA architecture embodies a number …

The theme of intrusion detection systems (IDS) is detection because prevention mechanisms
alone are not guaranteed to keep intruders out. The research focus of IDS is therefore on …

There is a significant body of research on distributed computing architectures,
methodologies and algorithms, both in the fields of fault tolerance and security. Whilst they …

The complexity of the software systems built today virtually guarantees the existence of
security vulnerabilities. When the existence of specific vulnerabilities becomes known …

We describe a general architecture for intrusion-tolerant enterprise systems and the
implementation of an intrusion-tolerant Web server as a specific instance. The architecture …
