Internet最初基本上是一个不设防的网络空间,其采用的TCP/IP,SNMP等协议的安全性很脆弱。它强调开放性和共享性,本身并不为用户提供高度的安全保护。随着Internet网上用户的日益增加,网上的犯罪行为也越来越引起人们的重视。Internet所提供的几乎无限的分布式计算能力已对人类的信息安全提出了空前严重的挑战。本文从Internet的安全问题的提出着手,分析了常见网络安全问题,得出了网络安全监控系统的设计的思路。
The Internet was originally a non-defensive cyberspace, the security of the protocols such as TCP / IP, SNMP adopted by it was very weak. Its emphasis on openness and sharing does not in itself provide users with a high level of security. With the increasing number of Internet users online, criminal activities on the Internet have drawn more and more attention. The almost unlimited distributed computing capabilities offered by the Internet have posed an unprecedented challenge to human information security. This paper starts with the proposal of the Internet security problem, analyzes the common network security problems, and draws the idea of network security monitoring system design.
