Intrusion tolerance

From Wikipedia, the free encyclopedia

Intrusion tolerance is a fault-tolerant design approach to defending information systems against malicious attack. Abandoning the conventional aim of preventing all intrusions, intrusion tolerance instead calls for triggering mechanisms that prevent intrusions from leading to a system security failure.

Projects in this area include the MAFTIA project (Malicious- and Accidental-Fault Tolerance for Internet Applications), which developed concepts and prototyped architectures, and the OASIS program, which implemented several intrusion-tolerant systems.
