XSS蠕虫在社交网络中的传播分析

摘要

通过分析社交网络的特点,将节点分为活跃节点和非活跃节点.针对XSS蠕虫的传播,分析其传播受到的影响因素,建立数学模型.仿真结果表明,节点访问偏向度对XSS蠕虫传播影响较小,而XSS蠕虫采用社会工程学的熟练度及节点安全意识,对XSS蠕虫传播影响较大.活跃节点的安全意识较大程度影响了XSS蠕虫传播效率,将活跃节点作为防御点和监控点的防御策略切实可行.%Peers in social network are divided into active nodes and inactive nodes after analyzing the features of social network.Mathematical model is built through analyzing the impact factors on XSS worms propagation.Simulations show that the impact of visit bias probability of nodes is small.The proficiency of social engineering used by XSS worms and the security consciousness of nodes can have a great impact on XSS worms propagation.Furthermore, the security consciousness of active nodes is very important and the strategy that active nodes are used as defensive points and monitoring points is feasible to defend against XSS worms.
