【摘要】：隨著政務(wù)信息化建設(shè)飛速發(fā)展,計(jì)算機(jī)網(wǎng)絡(luò)的應(yīng)用已逐步深入政府各職能部門,從而使得政務(wù)網(wǎng)絡(luò)存在的安全問題越來越突出。黨政機(jī)關(guān)政務(wù)網(wǎng)絡(luò)傳輸?shù)亩际钦⻊?wù)及其敏感重要數(shù)據(jù),而政務(wù)網(wǎng)絡(luò)中使用的安全產(chǎn)品為國產(chǎn)設(shè)備,國產(chǎn)的防火墻、IDS和IPS系統(tǒng)只能用來保護(hù)來自政務(wù)網(wǎng)絡(luò)外部的攻擊,給黨政機(jī)關(guān)信息網(wǎng)絡(luò)的安全管理工作造成了很大的不便。因此,針對黨政機(jī)關(guān)政務(wù)網(wǎng)絡(luò)協(xié)議分析的迫切需要,設(shè)計(jì)一款專門用于黨政機(jī)關(guān)政務(wù)網(wǎng)絡(luò)協(xié)議分析軟件來保護(hù)政務(wù)網(wǎng)絡(luò)的安全,具有很重要的現(xiàn)實(shí)意義。本文首先研究了最基本的TCP/IP協(xié)議、計(jì)算機(jī)端口知識以及網(wǎng)絡(luò)數(shù)據(jù)捕獲分析的關(guān)鍵技術(shù),探討了網(wǎng)絡(luò)數(shù)據(jù)包監(jiān)控分析的相關(guān)理論與技術(shù),從網(wǎng)絡(luò)防護(hù)的技術(shù)角度看,對網(wǎng)絡(luò)協(xié)議數(shù)據(jù)包進(jìn)行捕獲,并對數(shù)據(jù)包數(shù)據(jù)進(jìn)行過濾與分析,從中發(fā)現(xiàn)惡意代碼或非法行為,這種協(xié)議分析技術(shù)直到現(xiàn)在仍應(yīng)用于網(wǎng)絡(luò)安全設(shè)備。然后根據(jù)黨政機(jī)關(guān)政務(wù)網(wǎng)絡(luò)協(xié)議分析中的功能、性能、應(yīng)用的需求,對軟件進(jìn)行了結(jié)構(gòu)設(shè)計(jì),總體分為四大基本模塊:數(shù)據(jù)捕獲、數(shù)據(jù)過濾、協(xié)議分析、顯示存儲。最后通過編程實(shí)現(xiàn)了政務(wù)網(wǎng)絡(luò)數(shù)據(jù)分析軟件,對該軟件功能和性能進(jìn)行了分析測試。測試結(jié)果表明,黨政機(jī)關(guān)政務(wù)網(wǎng)絡(luò)數(shù)據(jù)分析軟件能夠快速進(jìn)行數(shù)據(jù)捕獲,協(xié)議解析詳細(xì),結(jié)果正確,協(xié)議解析層次顯示分明、內(nèi)容易于理解,對于網(wǎng)絡(luò)管理工作者來說,能及時(shí)全面地掌握和了解該網(wǎng)段的運(yùn)行及使用情況,有力地制止了政務(wù)網(wǎng)絡(luò)中非法或者惡意的行為。今后,在工作應(yīng)用當(dāng)中需進(jìn)一步努力改進(jìn)原有技術(shù),加大提高捕包效率,繼續(xù)增加方便實(shí)用的新功能,使界面設(shè)計(jì)更加明了簡潔,形成一個(gè)強(qiáng)大的復(fù)合的政務(wù)網(wǎng)絡(luò)數(shù)據(jù)分析軟件。
[Abstract]:With the rapid development of government information construction, the application of computer network has gradually penetrated into the various functional departments of the government, thus making the security problems of the government affairs network more and more prominent. Party and government organizations and government networks transmit government affairs and sensitive and important data, and the security products used in government affairs networks are domestic equipment. Domestic firewalls, IDs and IPS systems can only be used to protect attacks from outside government affairs networks. To the party and government organs information network security management caused great inconvenience. Therefore, according to the urgent need of the analysis of the network protocol between the Party and government organs, it is of great practical significance to design a software specially used for the analysis of the network protocol of the party and government organs to protect the security of the government affairs network. This paper first studies the most basic TCP/IP protocol, the knowledge of computer port and the key technology of network data capture and analysis, and discusses the relevant theory and technology of network data packet monitoring and analysis, from the point of view of network protection technology. The network protocol data packet is captured, and the packet data is filtered and analyzed to find malicious code or illegal behavior. This protocol analysis technique is still applied to network security devices. Then according to the function, performance and application requirements of the network protocol analysis of the party and government, the software is designed, which is divided into four basic modules: data capture, data filtering, protocol analysis and display storage. Finally, the government network data analysis software is realized by programming, and the function and performance of the software are analyzed and tested. The test results show that the party and government network data analysis software can quickly capture the data, the protocol analysis is detailed, the results are correct, the protocol analysis level is clear, the content is easy to understand, for network management workers, It can grasp and understand the operation and usage of the network segment in a timely and comprehensive way, and can effectively stop the illegal or malicious behavior in the government affairs network. In the future, we should make further efforts to improve the original technology, increase the efficiency of packet capture, continue to increase the convenient and practical new functions, and make the interface design more clear and concise. Form a powerful complex government network data analysis software.
