基于并发投影时序逻辑模型检测的入侵检测方法
首发时间:2010-06-07
摘要:基于投影时序逻辑模型检测的入侵检测方法具有描述网络入侵者分段攻击的能力,然而对并发攻击仍无能为力,因为该逻辑无法直接描述并发。针对此问题,在该逻辑的基础上定义了一种新的并发算子,并给出基于并发投影时序逻辑模型检测的入侵检测方法。对复杂攻击实例的检测表明,新方法可有效提高对并发攻击的检测能力。

Method based on model checking CPPTL for intrusion detection
Abstract:In this paper, the model-checking based intrusion detection technique is studied. The method based on model checking projection temporal logic for intrusion detection can describes piecewise network attacks but concurrent attacks. To this end, we define a novel concurrent operation and obtain a new method based on model checking concurrent propositional projection temporal logic for misuse detection. By example, we show that our method can detect concurrent attacks efficiently.
