| 摘 要： | This paper presents a novel probability generation algorithm to predict attacks from an insider who exploits known system vulnerabilities through executing authorized operations. It is different from most intrusion detection systems （IDSs） because these IDSs are inefficient to resolve threat from authorized insiders. To deter cracker activities, this paper introduces an improved structure of augmented attack tree and a notion of ＂minimal attack tree＂, and proposes a new generation algorithm of minimal attack tree. We can provide a quantitative approach to help system administrators make sound decision.

| Abstract: | This paper presents a novel probability generation algorithm to predict attacks from an insider who exploits known system
vulnerabilities through executing authorized operations. It is different from most intrusion detection systems (IDSs) because
these IDSs are inefficient to resolve threat from authorized insiders. To deter cracker activities, this paper introduces
an improved structure of augmented attack tree and a notion of “minimal attack tree”, and proposes a new generation algorithm
of minimal attack tree. We can provide a quantitative approach to help system administrators make sound decision.
