摘要

合理地建立蠕虫传播模型将有助于更准确地分析蠕虫在网络中的传播过程。首先通过对分层的异构网络环境进行抽象

在感染时间将影响到蠕虫传播速度的前提下使用时间离散的确定性建模分析方法

推导出面向异构网络环境的蠕虫传播模型Enhanced-AAWP。进而基于Enhanced-AAWP模型分别对本地优先扫描蠕虫和随机扫描蠕虫进行深入分析。模拟结果表明

NAT子网的数量、脆弱性主机在NAT子网内的密度以及本地优先扫描概率等因素都将对蠕虫在异构网络环境中的传播过程产生重要的影响。

Abstract

A logical worm propagation model contributes to the analysis of how exactly various worms spread in Internet.With the abstract of heterogeneous network environments

and considering the impact of infection time on worm propa-gation

a heterogeneous network oriented worm propagation model namely Enhanced-AAWP was derived using discrete time and deterministic approximation.Then

the worms which employed local preference scanning or random scanning were studied based on Enhanced-AAWP.As the simulation results show

the amount of NAT

the density of vulnerable hosts in NATs

and the probability of local preference scanning are influencing factors during the course of worm propa-gations in heterogeneous network environments.
