Abstract:

Concerning the secondary attack problem of virus in cloud computing, data center and other virtual network-based environments, the virus propagation and immune mechanism under the background of dynamic platform defense was studied, and a heterogeneous backup based network virus defense method was proposed. Firstly, the process of secondary attack of redundant backup was analyzed, and the law of virus action was summarized. At the same time, combined with the idea of dynamic platform defense, the heterogeneous platform state node was introduced, and a Susceptible-Escaped-Infected-Removed-Heterogeneous-Susceptible (SEIRHS) virus propagation model was proposed. Secondly, the local stability at the equilibrium point of the model was proved by using the Routh-Hurwitz stability criterion, and the basic reproductive number was solved. Finally, the proposed model was compared with the traditional Susceptible-Infected-Removed (SIR) and Susceptible-Escaped-Infected-Removed (SEIR) models through simulation analysis, the stability of the model was verified, and the effect of virus propagation influencing factors on virus spread scale was discussed. The simulation results show that the proposed model can objectively reflect the propagation law of virus in the network, and effectively improve the network’s defense effect against the virus by reducing the node degree, increasing the Infected-Heterogeneous (I-H) state transition probability, and reducing the probability of being hidden by the virus during backup, etc.

摘要:

针对云计算、数据中心等基于虚拟网络的环境中病毒二次攻击的问题,研究了平台动态防御背景下的病毒传播及免疫机理,并提出一种异构备份式的网络病毒防御方法。首先,分析冗余备份发生二次攻击的过程,并总结病毒作用规律;同时,结合平台动态防御的思想,引入异构平台状态节点,并提出了易感?潜伏?感染?免疫?异构?易感(SEIRHS)病毒传播模型;其次,运用劳斯?赫尔维茨稳定性判据证明了模型平衡点处的局部稳定性,并求解基本再生数;最后,通过实验仿真分析对比了所提模型与传统易感?感染?免疫(SIR)模型、易感?潜伏?感染?免疫(SEIR)模型,并验证了所提模型的稳定性,探讨了病毒传播影响因子对病毒扩散规模的作用结果。仿真结果表明,所提模型能客观反映病毒在网络中的传播规律,并通过降低节点度、提高感染?异构(I-H)状态转移概率、降低备份时已被病毒潜伏的概率等有效提升网络对病毒的防御效果。
