摘要: Network diagnosis and attack prediction can help the network administrator to take timely actions defend against well-planned attacks that exploit a chain of vulnerabilities. One important data source for such analysis is alerts generated by intrusion detection systems (IDS) deployed over network. However, IDS typically generates overwhelming amount alerts, where one cannot simply aggregate or discard. In addition, chance successful depends on many hidden factors as system status attacker power, thus dependencies among exploits conditions are too complicated analyze under probability framework. this paper, we employ expert deal with uncertainties conduct certainty factor inference. We show in fuzzy tractable propose an algorithm predict potential attacks. Finally, give case study illustrate our evaluate effectiveness approach DARPA sets. Copyright © 2011 John Wiley & Sons, Ltd.
