TCP/IP协议安全漏洞
摘要
随着计算机网络技术的发展，信息安全问题越来越受到国家的关注，网络安全已经成为计算机网络通信领域的重点。这篇论文的从目前使用的TCP/IP协议入手来研究问题，从TCP/IP协议的安全性进行较为全面的解析，从TCP/IP的总体概括、现在存在安全隐患、以及各个层次之间安全问题进行了比较深入的讨论。然后用现在最为流行的Snifer工具从实验的角度上来分析数据包的安全情况，最后从SYN的攻击代码来分析TCP/IP协议，并且实现了几种防御SYN的方法。
本文在介绍因特网中使用的TCP/IP协议的基础上，对TCP/IP协议的安全性进行了较为全面的讨论，从理论上分析了协议中几种主要的安全隐患。由于TCP/IP协议一开始的实现主要目的是用于科学研究的，所以很少考虑安全性方面的东西。但随着其应用的普及，它已经成为了Internet网络通信协议的标准。希望本论文能对未来的信息社会中网络安全环境的形成有所帮助。

ABSTRACT
Abstract: With the development of computer network technology, the government concerns more and more the message safety, Now, network security has become a key area of computer network communications. The paper start with the currently used TCP/IP protocol to study the problem. From the security On TCP/IP protocol we give more comprehensive analysis, Now from the exist security risks, and security issues between the various levels we give more in-depth discussion. Then using the most popular tool of Snifer to come up safe circumstance that analytical data wrap from the experience angle, and at last we analyze from the SYN attacking code to TCP/IP protocol, and achieve several defenses the SYN attacking.
This paper describes the use of the Internet's TCP / IP protocol on the basis of TCP / IP protocol security for a more comprehensive discussion of the agreement from the theoretical analysis of several major security risk. As TCP / IP protocol began with the main purpose is for scientific research to achieve, so little regard for the safety of things. But with the popularity of its application, it has become the standard Internet network communication protocol. Hope that this paper will in the future information society, network security environment, help the formation of
