浅谈计算机网络安全漏洞及防范措施

浅谈计算机网络安全漏洞及防范措施xxxxxxxx摘要：随着计算机网络在人类生活领域中的广泛应用，针对计算机网络的攻击事件也随之增加。网络已经无所不在的影响着社会的政治、经济、文化、军事、意识形态和社会生活等各个方面。同时在全球范围内，针对重要信息资源和网络基础设施的入侵行为和企图入侵行为的数量仍在持续不断增加，网络攻击与入侵行为对国家安全、经济和社会生活造成了极大的威胁。计算机病毒不断地通过网络产生和传播，计算机网络被不断地非法入侵，重要情报、资料被窃取，甚至造成网络系统的瘫痪等等，诸如此类的事件已给政府及企业造成了巨大的损失，甚至危害到国家的安全。网络安全已成为世界各国当今共同关注的焦点，网络安全的重要性是不言而喻的，因此，对漏洞的了解及防范也相对重要起来。介绍了计算机网络和网络安全的概念，对于互联网的安全问题提出了解决方案。关键词：计算机网络、网络安全、防火墙、局域网DiscusstheonlinesecurityloopholeoftheconputerandprecautionarymensuressimplyxxxxxxxxAbstract:Withthepopularityofcomputernetworkinhumanlifefield,theattackingmattersaimedatcomputernetworkhavealsoincreased.Networkhasomnipresentimpactsforvariousfieldslikepolitics,economy,culture,militaryaffairs,ideologyandsociallives,etc.Simultaneously,inglobalrange,theamountofinvasionandinvasionattemptingaffairsthataimedatimportantresourceandnetworkbasicequipmentshaskeptincreasing.Thenetworkattackingandinvasionhavesignificantthreatonnationalsecurity,economyandsociallives.Computervirushavebeenproducedandspreadceaselessly;computernetworkhasbeeninvadedillegally;importantinformationanddatahavebeenstolenandevennetworksystemhasbeencrashed.Sucheventshavecausedenormousdamagesforgovernmentsandenterprises,sometimesfornationalsecurity.Therefore,networksecurityhasbeenthefocusofeverycountryintheworldanditsimportanceisself-evidenced.Hence,itiscomparativelyimportanttoknowthecomputerholesandprecaution.Haveintroducethecomputernetworkandconceptoftheonlinesecurity,hasputforwardthesolutiontothesecurityproblemofInternet,thinkakindofimportantmeanstorealizesafetymeasureofthenetworkisthetechnologyoffirewall.Keyworks:Computernetwork、Networksecurity、Firewall、Localareanetwork目录1、引言.............................................................................................................................................31.1研究的背景.........................................................................................................................31.2研究的范围.........................................................................................................................32、网络安全.....................................................................................................................................32.1计算机网络安全的现状.....................................................................................................32.2计算机网络安全漏洞的种类及成因.................................................................................42.3计算机网络面临的威胁.....................................................................................................52.4计算机网络安全防范策略.................................................................................................53、防火墙技术.................................................................................................................................53.1防火墙的简介.....................................................................................................................53.2防火墙的关键技术.............................................................................................................64、防病毒技术.................................................................................................................................74.1防病毒技术概述.................................................................................................................74.2网络防病毒的基本方法.....................................................................................................85、安全扫描技术.............................................................................................................................95.1安全扫描概述.....................................................................................................................95.2常用安全的扫描技术.........................................................................................................96、局域网的攻防...........................................................................................................................106.1局域网的简介...................................................................................................................106.2局域网系统漏洞攻防.......................................................................................................116.3局域网病毒特点及攻防...................................................................................................116.4局域网安全攻防武器.......................................................................................................117、确保网络安全的手段...............................................................................................................117.1写下你的安全策略...........................................................................................................117.2防火墙必不可少...............................................................................................................127.3随时更新桌面防病毒系统...............................................................................................127.4强化您的服务器...............................................................................................................127.5补丁策略必不可少............
