This paper from the currently used TCP / IP protocol to study problems, from the TCP / IP protocol security carries on a more prehensive analysis, from the TCP / IP is overall and wraparound, now hidden safety problems, as well as various levels between safety issues more indepth discussion. And now the most popular Snifer tools from the perspective of experimental analysis data packet safety situation, finally from the SYN attack code analysis of TCP / IP protocol, and the realization of several defense SYN method.Based on the introduction of the Internet using TCP / IP protocol based on TCP / IP protocol, the security to undertake relatively prehensive discuss, from theoretic analysis protocol in several major security hidden danger. Because the TCP / IP protocol at the start of the implementation is mainly used for scientific research, so rarely consider the security aspects. But with its application, it has already bee a Internet network munication protocol standard. Hope this thesis could in the future information society network security environment for the formation of help.Key Words：TCP / IP protocol；security protocol；service；protocol layer目 錄摘 要 IAbstract II1 TCP/IP協(xié)議概述 1 TCP/IP協(xié)議定義 1 TCP/IP協(xié)議的主要特點(diǎn) 2 TCP/IP協(xié)議的總體概況 22 各協(xié)議層存在的安全漏洞 3 鏈路層存在的安全漏洞 3 網(wǎng)絡(luò)層漏洞 4 IP漏洞 4 ARP欺騙 4 路由欺騙 5 DNS欺騙 5 攔截TCP連接 5 使用TCP/SYN報(bào)文段淹沒(méi)服務(wù)器 53 關(guān)于TCP/IP協(xié)議族存在的脆弱性剖析 6 TCP/IP協(xié)議族存在脆弱性 6 應(yīng)用服務(wù)不容樂(lè)觀 7 文件傳輸協(xié)議 7 Web服務(wù) 7 提高網(wǎng)絡(luò)可信度 84 TCP/IP狀態(tài)轉(zhuǎn)移 8 TCP狀態(tài)轉(zhuǎn)移圖和定時(shí)器 8 網(wǎng)絡(luò)入侵方式 9 偽造IP地址 9 TCP狀態(tài)轉(zhuǎn)移的問(wèn)題 10 定時(shí)器問(wèn)題 11 利用網(wǎng)絡(luò)監(jiān)控設(shè)備觀測(cè)網(wǎng)絡(luò)入侵 12 偽造IP地址 12 虛假狀態(tài)轉(zhuǎn)移 12結(jié) 論 14參考文獻(xiàn)： 15致 謝 1611 TCP/IP協(xié)議概述 TCP/IP協(xié)議定義 協(xié)議是互相通信的計(jì)算機(jī)雙方必須共同遵從的一組約定。之所以說(shuō)TCP/IP是一
