摘要: 随着互联网技术的蓬勃发展,网络安全威胁层出不穷,各国对网络安全越来越重视。在分析总结网络安全威胁的原理特点后,给出三种主动安全威胁模型,即饱和安全威胁、删除安全威胁、篡改安全威胁。利用OPNET仿真工具建立多业务通信网络模型,其中网络节点模型是基于排队论而建立的模型。实验仿真设置不同业务强度参数以便获得不同网络状态下的网络性能状态。利用模糊综合评价方法对网络安全威胁效果进行评估。

关键词: 网络安全威胁, OPNET仿真技术, 效果评估, 排队论

Abstract: With the booming development of Internet technology, network security threats force every country to pay more and more attention to network security. By analyzing and summarizing the principles of network security threats, three kinds of proactive security threats are proposed in this paper, including saturation security threats, deleting security threats, and tampering security threats. OPNET is employed as the simulation tool to establish multi-service communications network model, in which the node are based on the queuing theory model. In addition, different traffic intensity parameters are designed to simulate the network performance under various running situations. Fuzzy comprehensive evaluation method is used to assess the effect of network security threats.

Key words: network security threats, OPNET simulation technology, effect evaluation, queue theory
