作为全球使用范围最大的信息网,Internet自身协议的开放性极大地方便了各种联网的计算机,拓宽了共享资源。但是,由于在早期网络协议设计上对安全问题的忽视,以及在管理和使用上的无政府状态,逐渐使Internet自身安全受到严重威胁,与它有关的安全事故屡有发生。本文主要分析了目前最为威胁网络安全的因素,介绍了网络安全的分类,综合介绍了目前的一些保证网络安全的措施。
As the most widely used information network in the world, the openness of Internet’s own protocol greatly facilitates the networking of computers and widens the sharing of resources. However, due to the neglect of security problems in the design of early network protocols, as well as the management and use of the anarchy, the Internet itself is gradually threatened with serious threats, and security incidents related to it occur frequently. This article analyzes the most threats to the current network security factors, introduced the classification of network security, introduced some of the current measures to ensure network security.
