网络涌现现象对网络安全的影响研究

Network Security Research by Network Emergence

网络安全是网络管理中的一个至关重要问题,随着计算机网络在连结信息能力、流通能力快速提高的同时,基于网络连接的安全问题也日益突出,因此认清网络的脆弱性和潜在威胁,采取强有力的安全策略,对于保障网络的安全性将变得十分重要。Internet作为一个复杂的网络自适应系统,它所涌现出的突现行为对网络安全构成了一定影响。该文首先探讨了Internet网络拓扑结构呈现出Power-law这一网络涌现现象的生成机制,对这种涌现现象的受限生成过程进行了数学描述,然后讨论了该网络涌现现象对网络安全的影响,最后对网络安全的防范措施提出了建议。

Network security is very important to network administration.Along with the speedy advance of information connecting and delivery capacity of the network,its security problems in network connection have been more and more obvious.Thus recognizing the fragility and potential threat of network,and implementing powerful security strategies have become quite important to ensure the network security.As a complex adaptive system,the emergence phenomenon of In-ternet has partly affected the network security.The article firstly discusses the mechanism why Internet topology structure appears Power-law,one kind of network emergence phenomenon and mathematically describes Constrained Generating Procedures of this emergence phenomenon;then it discusses the network emergence's influence over network security;fi-nally the article offers suggestions as precaution measures to network security.
