網(wǎng)絡(luò)數(shù)據(jù)包監(jiān)聽與分析工具的模擬實(shí)現(xiàn)

1、吉林建筑大學(xué)畢業(yè)設(shè)計(jì)(論文)I摘要如今，網(wǎng)絡(luò)已經(jīng)滲透到了生活的方方面面，購(gòu)物、旅行、醫(yī)療等等都在網(wǎng)絡(luò)的支撐下變的更加便捷。網(wǎng)絡(luò)的發(fā)展有目共睹，但是網(wǎng)絡(luò)的效率和安全問(wèn)題也不容忽視。網(wǎng)絡(luò)的興盛，也使得很多不法分子為了利益方面的追求而破壞網(wǎng)絡(luò)規(guī)則，通過(guò)網(wǎng)絡(luò)來(lái)竊取用戶信息，甚至造成財(cái)產(chǎn)損失，這就需要網(wǎng)絡(luò)監(jiān)聽工具。本文實(shí)現(xiàn)了基于數(shù)據(jù)包的監(jiān)聽系統(tǒng)，該系統(tǒng)可以對(duì)數(shù)據(jù)包進(jìn)行捕獲，通過(guò)設(shè)置硬路由器的監(jiān)聽端口，利用以太網(wǎng)絡(luò)的廣播特性攔截所有經(jīng)過(guò)該機(jī)器的網(wǎng)絡(luò)

2、上傳送的數(shù)據(jù)。數(shù)據(jù)包過(guò)濾采用TCPIP協(xié)議來(lái)篩選數(shù)據(jù)并根據(jù)端口號(hào)來(lái)選擇特定數(shù)據(jù)包分析主要用來(lái)對(duì)過(guò)濾之后得到的數(shù)據(jù)進(jìn)行分析。該系統(tǒng)能進(jìn)行TCP，UDP，HTTP協(xié)議分析使用VC作為開發(fā)工具。系統(tǒng)利用Winsock鉤子截獲Winsock調(diào)用，從而攔截TCPIP數(shù)據(jù)包，再利用TCPIP協(xié)議的封包結(jié)構(gòu)分析所截獲的數(shù)據(jù)，提取需要的數(shù)據(jù)對(duì)其進(jìn)行控管規(guī)則的檢查認(rèn)證，從而確定Socket連接是否允許通過(guò)。通過(guò)將網(wǎng)卡設(shè)置為混合模式來(lái)實(shí)現(xiàn)數(shù)據(jù)包的捕獲，在捕

3、獲數(shù)據(jù)包后，利用TCPIP協(xié)議的詳細(xì)設(shè)計(jì)對(duì)抓到的數(shù)據(jù)包進(jìn)行分析。本設(shè)計(jì)還提供了過(guò)濾，和把數(shù)據(jù)包存入數(shù)據(jù)庫(kù)功能，使得本設(shè)計(jì)的使用范圍和可依賴度極大的提高。工具使用VC6.0進(jìn)行開發(fā)，通過(guò)MFC設(shè)計(jì)界面，總體功能完善，外觀簡(jiǎn)潔大方。當(dāng)捕獲到數(shù)據(jù)包后，對(duì)數(shù)據(jù)進(jìn)行分析，可以使每一項(xiàng)清晰的顯示在界面中。關(guān)鍵詞關(guān)鍵詞數(shù)據(jù)包捕獲；數(shù)據(jù)包監(jiān)聽；數(shù)據(jù)包捕獲；數(shù)據(jù)包監(jiān)聽；Winsock吉林建筑大學(xué)畢業(yè)設(shè)計(jì)(論文)III目錄摘要...............
