摘要在互联网时代的大浪潮下,全民信息化时代已经到来,互联网给人们的生活带来许多便利,但是网络环境的复杂程度也是非常之高的,因此网络空间安全便是现如今互联网时代大背景下的重要安全课题。现在网络上已经有了许多的网络安全竞赛的组织机构和团体,在校园中也可以开发出具有相应功能的网络安全竞赛系统,来更好的适配大学本身对于这方面的需求。为了使相关组织能够更好的开展网络安全竞赛,本文设计与开发了这套网络安全竞赛系统。首先,本文阐述了该系统的研究背景以及研究意义。之后,对于本系统所使用的技术进行了分析。本系统使用C#作为编程语言,采用ASP.NET的方式创建应用程序,系统的数据库采用了SQLServer数据库。之后,本文对于该系统进行了开发可行性的分析。然后,本文软件工程的开发方式对于该系统进行了系统需求分析、系统概要设计、系统详细设计和软件测试等。该系统实现了登录注册、竞赛题目、比赛规则、裁判信息、队伍信息、回答问题、队伍排名、论坛交流等功能。本系统经过测试,系统运行状态正常,各项功能使用情况良好,用户体验上使用方便。为大学生网络安全能力的检验提供了一个真实有效的平台。关键词:互联网;ASP.NET;网络安全;竞赛系统DesignandDevelopmentofNetworkSecurityCompetitionSystemAbstractIntheeraoftheInternet,theeraofuniversalinformationiscoming.TheInternetgivespeoplealotofconvenience.Butthecomplexityofthenetworkenvironmentisveryhigh,socyberspacesecurityisanimportantsecurityissueunderthebackgroundoftheeraoftheInternet.Nowinthenetwork,wehaveownalotoforganizationsandteamstoorganizeracesofcyberspacesecurity,wecanalsodevelopcorrespondingfunctionsofthenetworksecuritycompetitionsystem,tobetteradapttoouruniversityitselfforthisdemand.Inordertoenabletherelevantorganizationstobettercarryoutnetworksecuritycompetition,thisarticledesignedanddevelopedthenetworksecuritycompetitionsystem.Firstofall,thispaperdescribestheresearchbackgroundandsignificanceofthesystem.Afterthat,thetechniquesusedinthesystemwereanalyzed.ThesystemusesC#asaprogramminglanguage,usesASP.NETtocreatetheapplication,usesMicrosoft'sSQLServerdatabaseasdatastoragetobethebackgrounddatabasestorage.Then,thispaperanalyzesthefeasibilityofthesystem.Then,thedevelopmentofsoftwareengineeringinthispaperhascarriedonthesystemdemandanalysis,thesystemoutlinedesign,thesystemdetaileddesignandthesoftwaretesttothissystem.Thesystemtoachievetheloginregistration,competitiontopics,rulesofthegame,therefereeinformation,teaminformation,answerquestions,teamrankings,forumexchangeandotherfunctions.Afterbeingtested,thesystemrunsnormal,theuseofvariousfunctionsisingoodcondition,usersareeasytouse.Itprovidesarealandeffectiveplatformfortestingnetworksecuritycapabilitiesofstudents.KeyWords:Internet;ASP.NET;CyberSecurity;CompetitionSystem目录摘要.........................................................................................................................................IAbstract......................................................................................................................................II引言.........................................................................................................................................11绪论........................................................................................................................................41.1课题研究背景及意义..................................................................................................41.2国内外的研究现状..................................................................
