计算机病毒解析与防范技术研究摘要伴随着计算机系统的不断发展,目前计算机病毒已成为系统以及网络安全的巨大威胁。因此要对计算机病毒常见类型以及基础常识进行把握,在这样的前提下如果遭遇病毒不会变的束手无策。基于此,本文对计算机病毒的定义、传播方式以及受到感染之后的现象进行详细分析,并分析了计算机病毒的传播方式,主要包括基于网络的病毒传播模式、计算机常见病毒、几个经典的计算机病毒传播模型,进一步研究了计算机病毒防御方法,包括基于主机的检测方案、基于网络的检测策略、创建一套完善的病毒防护机制、对防治技术进行不断完善,同时对病毒检测手段进行升级,最后对病毒防范措施进行详细分析,除了漏洞扫描以及防火墙等技术之外,还包括反病毒、计算机病毒免疫技术,以便最大限度地减少计算机病毒造成的危害。关键词:计算机病毒;计算机病毒传播途径;预防计算机病毒AbstractWiththecontinuousdevelopmentofcomputersystems,computerviruseshavebecomeagreatthreattosystemandnetworksecurity.Therefore,weshouldgraspthecommontypesofcomputervirusesandbasiccommonsense,undersuchapremise,ifencounterviruseswillnotchangeataloss.Basedonthis,thispapermakesadetailedanalysisofthedefinition,modeoftransmissionandthephenomenaafterinfectionofcomputerviruses,andanalysesthemodeoftransmissionofcomputerviruses,mainlyincludingnetwork-basedvirustransmissionmode,commoncomputerviruses,severalclassicalcomputervirustransmissionmodels,andfurtherstudiesthemethodsofcomputervirusdefense,includinghost-baseddetection.Measuringscheme,network-baseddetectionstrategy,establishingasetofperfectvirusprotectionmechanism,improvingpreventionandcontroltechnology,andupgradingvirusdetectionmeans.Finally,theviruspreventionmeasuresareanalyzedindetail.Inadditiontovulnerabilityscanningandfirewalltechnologies,anti-virusandcomputervirusimmunetechnologiesarealsoincludedinordertominimizethenumberofcomputers.Theharmcausedbyvirus..KEYWORDS:Computerviruses;Computervirustransmissionroute;Preventionofcomputerviruses目录摘要........................................................................IAbstract....................................................................II1计算机病毒的概念及危害.....................................................11.1计算机病毒的概念.....................................................11.2计算机病毒的特征.....................................................11.3计算机病毒的危害.....................................................12计算机常见病毒分析与病毒传播...............................................32.1计算机常见病毒.......................................................32.1.1系统病毒.......................................................32.1.2木马病毒.......................................................32.1.3脚本病毒.......................................................42.2基于网络的病毒传播模式...............................................42.2.1通过电子邮件进行传播...........................................42.2.2通过扫描系统漏洞传播...........................................52.2.3通过无线电的方式传播...........................................52.3几个经典的计算机病毒传播模型.........................................62.3.1SIS模型.......................................................62.3.2SIR模型.......................................................62.4案例分析.............................................................82.4.1感染式蠕虫.....................................................82.4.2勒索病毒.......................................
