Intrusion Tolerance for Unclassified Networked Systems

摘要: Abstract : Information such as security advisories, emergency recommendations, e-government information, etc., is unclassified, but its availability and integrity may be vital. Such data are intended to made widely available thus need accessible through open networks the Internet. The systems distributing this kind of information usually built from COTS hardware software, since their functions do not require specific software or development. Openness use make these very vulnerable, traditional means insufficient achieve required integrity. In that case, fault tolerance can viewed a complementary, valuable technique cope with possible intrusions, well accidental failures system components. This paper presents techniques intrusion tolerance, describe some recent experimental architectures, developed by European project MAFTIA DARPA DIT.
