【正文】 計(jì)算機(jī)網(wǎng)絡(luò)安全及防護(hù)畢業(yè)設(shè)計(jì)論文 摘 要 本文從計(jì)算機(jī)網(wǎng)絡(luò)面臨的各種安全威脅，系統(tǒng)地介紹網(wǎng)絡(luò)安全技術(shù)。并針對(duì)校園網(wǎng) 絡(luò)的安全問題進(jìn)行研究，首先分析了高校網(wǎng)絡(luò)系統(tǒng)安全的隱患，然后從構(gòu)建安全防御體 系和加強(qiáng)安全管理兩方面設(shè)計(jì)了校園網(wǎng)絡(luò)的安全策略。本次論文研究中，我首先了解了 網(wǎng)絡(luò)安全問題的主要威脅因素，并利用網(wǎng)絡(luò)安全知識(shí)對(duì)安全問題進(jìn)行剖析。其次，通過 對(duì)網(wǎng)絡(luò)技術(shù)的研究，得出校園網(wǎng)也會(huì)面臨著安全上的威脅。最后，確立了用 P2DR 模型 的思想來建立校園網(wǎng)的安全防御體系。并得出了構(gòu)建一套有效的網(wǎng)絡(luò)安全防御體系是解 決校園網(wǎng)主要威脅和隱患的必要途徑和措施 . 關(guān)鍵詞 : 網(wǎng)絡(luò)安全，安全防范，校園網(wǎng) II ABSTRACT In this paper, a variety of puter work security threats faced by the system to introduce the work security for the safety of the campus work to study, first of all an analysis of the safety of colleges and universities hidden work and then build a security defense system and strengthen the security management of both the design of the campus work security policy. The research paper, I first learned about the major issues of work security threats and take advantage of work security knowledge to analyze the security issues. Secondly, through the work technology, will e to campus work is faced with security , P2DR model established with the idea to create a campus work security defense system.. And e to build an effective work security defense system to address major threats to the campus work and the hidden ways and measures necessary.
