校园网或企业网网络安全方案设计和实现的文档摘要随着计算机技术突飞猛进的发展，互联网的应用也越来越广泛，在网络环境下运行的各种应用系统越来越多，通过网络传输的各种信息也在不断增加。从目前中小型企业计算机技术的应用情况来看也是如此，目前中小型企业已经建立了企业网站，电子邮件等系统，并且已经实施了ERP、电子商务、IJR等信息系统，许多重要信息都存储在网络服务器中，因此网络系统的安全至关重要。这就要求我们对安全问题进行深入分析研究，在整个中小型企业建立多层次的网络安全体系。本文立足于中小型企业网络安全的规划设计与实施，对中小型企业网络系统方面存在的安全问题进行了深入分析，针对这些问题给出了总体解决方案并在中小型企业内进行了实施。通过中小型企业网络安全的规划设计和实施，提高了中小型企业网络系统的安全性和稳定性。同时随着计算机技术的不断发展，对网络系统的安全性提出了更高的要求，因此中小型企业会根据网络系统不断发展的要求，进一步规划设计出更加适合中小型企业发展的网络安全系统，满足中小型企业信息化建设不断发展的要求。关键词：网络安全；VLAN划分；用户权限；安全策略；病毒防范AbstractWiththerapiddevelopmentofthecomputertechnology,theInternetismoreandmorewidely,moreandmoreapplicationsystemsrunninginnetworkenvironment,throughavarietyofinformationnetworktransmissionisalsoincreasing.Theapplicationofcomputertechnologyinsmallandmedium-sizedenterprisesatpresentisso,thesmallandmedium-sizedenterpriseshaveestablishedenterprisewebsite,emailsystem,andhaveimplementedERP,e-commerce,IJRandotherinformationsystems,manyimportantinformationarestoredinthenetworkserver,sothesecurityofnetworksystem.Thisrequiresustostudyonsecurityissues,theestablishmentofnetworksecurityinthemulti-levelsystemofsmallandmediumenterprises.PlanningdesignandImplementationBasedonthesmallandmedium-sizedenterprisenetworksecurity,securityproblemsofthesmallandmedium-sizedenterprisenetworksystemareanalyzed,inordertosolvetheseproblemsaregiventhegeneralsolutionandinthesmallandmedium-sizedenterprisesintheimplementationof.Throughtheplanningdesignandimplementationofsmallandmedium-sizedenterprisenetworksecurity,improvethesmallandmedium-sizedenterprisenetworksystemsecurityandstability.Atthesametime,withthecontinuousdevelopmentofcomputertechnology,putforwardhigherrequirementsonthesecurityofthenetworksystem,sosmallandmedium-sizedenterpriseswillbebasedonthedevelopmentofthenetworksystem,furtherplanninganddesignofnetworksecuritysystemismoresuitableforthedevelopmentofsmallandmediumenterprises,informatizationofsmallandmediumenterprisestomeetthedemandofthedevelopmentof.Keywords:networksecurity;userrights;securitypolicy;virusprevention目录摘要·····························IAbstract···························II目录····························III第1章绪论··························11.1研究的背景······················11.2研究的意义······················11.3研究内容······························2第2章中小型企业网络安全问题及规划设计············12.1中小型企业网络安全存在的问题·············12.2网络系统平台安全系统设计···············32.2.1微软域用户策略部署方案设计···········32.2.2防火墙部署及VLAN规划设计············42.3用户权限管理系统设计·················52.3.1用户与角色管理设计···············6...
