摘要:信息時代,計算機網(wǎng)絡(luò)在現(xiàn)代社會之中得到了更為廣泛的應(yīng)用。計算機網(wǎng)絡(luò)安全不但屬于個人信息安全的狹義層面問題,更加是國家、社會、公共信息的安全問題。一旦計算機網(wǎng)絡(luò)存在安全問題,導(dǎo)致的不但是龐大的經(jīng)濟損失,還有可能對國家安全形成威脅影響。由此可見,計算機網(wǎng)絡(luò)安全已經(jīng)成為世界范圍內(nèi)的重要事項。該文就計算機網(wǎng)絡(luò)安全存在的隱患問題進行研究,并制定了科學(xué)有效的防范措施。對提升計算機網(wǎng)絡(luò)系統(tǒng)整體安全水平,營造可靠、優(yōu)質(zhì)的網(wǎng)絡(luò)應(yīng)用環(huán)境,提升實踐工作效率,符合新時期快速發(fā)展需要,有重要的實踐意義。

Abstract: The information age, the computer network in the modern society are being used more and more widely. Narrow level computer network security problems not only belong to the personal information security, more is the national security, social, public information. Once the existence of computer network security problem, cause not only the huge economic losses, and may pose a threat to national security. Thus, the security of computer network has become the important matters in the world. Research problems in computer network security in existence, and developed a scientific and effective preventive measures. To improve the overall level of safety of computer network system, network application environment to create reliable, quality, promote the practice work efficiency, meet the needs of the rapid development in the new period, have important practical significance.
Key words: computer; network security; preventive measures
做好計算機網(wǎng)絡(luò)安全管理,制定科學(xué)的防范措施尤為重要。由于計算機網(wǎng)絡(luò)系統(tǒng)包含一定的結(jié)構(gòu)性問題,因此較易受到非法的入侵攻擊影響,增加了安全防范的難度。為此,更應(yīng)真正的加強理論研究,分析引發(fā)計算機安全隱患的內(nèi)在成因,制定周密的技術(shù)策略,方能使計算機網(wǎng)絡(luò)安全問題得到妥善的解決。
1 計算機網(wǎng)絡(luò)安全隱患問題
1.1 網(wǎng)絡(luò)攻擊問題
計算機系統(tǒng)十分龐大,結(jié)構(gòu)復(fù)雜,因而即使是世界高手、頂尖開發(fā)者,也無法保證盡善盡美。另外,還會有可能本著某種商業(yè)目標或是政治目的,系統(tǒng)開發(fā)人會故意預(yù)留后門。因而導(dǎo)致計算機系統(tǒng)內(nèi)部包含較為嚴重的安全漏洞,較易被黑客利用進行攻擊。具體的攻擊形式包括拒絕服務(wù)、利用型、信息收集、虛假信息以及腳本跨站攻擊等。……
