Improvement to Ontology-based Intrusion Detection System

摘要

An improved Ontology-based Intrusion Detection System (OIDS) was proposed to solve the problems that traditional IDSs can not deal with.The new model proposed can provide more detailed information and the most comprehensive and accurate description of invasion semantics to the parser.With the three strategies of search, correlation and reasoning, OIDS is able to get more accurate descriptions of invasion situation, which makes the collaboration of IDSs more convenient, and makes OIDS smart, so as to improve the recall rate and accuracy of detections.
