Ｉｎｔｅｒｎｅｔ的普及提高了社会的信息化水平，但是随之所暴露出来的信息安全问题也越来越多。这是因为Ｉｎｔｅｒｎｅｔ的出现主要是为了解决不同结构、不同操作系统、不同网络协议的各种网络互连问题，所以在Ｉｎｔｅｒｎｅｔ出现的初期，不可能对开放、共享有限制的安全机制设计得很完善。同样， ＴＣＰ／ＩＰ协议主要的意义在于实现网络的互连，而在安全方面存在许多漏洞。本文就Ｉｎｔｅｒｎｅｔ安全问题的具体表现及关键的技术性防范措施进行了论述。
The popularization of Internet has raised the level of informatization of society, but the information security problems exposed subsequently are more and more. This is because the emergence of the Internet is mainly to solve various network interconnection problems of different structures, different operating systems and different network protocols. Therefore, it is impossible to design a perfect open and limited shared security mechanism in the initial stage of Internet emergence . Similarly, the main significance of the TCP / IP protocol is to achieve network interconnection, and there are many security vulnerabilities. This article discusses the specific performance of Internet security and key technical precautions.
