计算机网络安全现状与防护对策【摘要】21世纪是计算机互联网技术飞速发展的新世纪,网络信息已经成为社会发展必不可少的重要组成部分。目前它涉及到政府、经济、文化、军事等诸多领域,因此计算机网络的安全重要性不言而喻。然而,由于计算机网络形式的多样性,连接功能的终端销售,网络的开放性,导致网络信息容易受到黑客攻击,计算机系统是容易受到恶意软件的攻击。本文先简述了计算机网络安全的概念,然后阐述了计算机网络安全的现状以及常见安全威胁,并针对问题提出了网络安全的防范对策。【关键词】计算机网络安全;现状;防护对策ABSTRACTInthe21stcenturyistherapiddevelopmentofcomputerInternettechnologyinthenewcentury,networkinformationhasbecomeanindispensableimportantpartofsocialdevelopment.Nowitcomestothegovernment,economy,culture,military,andmanyotherareas,andthecomputernetworksafetyimportanceisself-evident.However,duetothediversityofcomputernetwork,connectionterminalsales,networkopenness,leadtonetworkinformationvulnerabletohackerattacks,computersystemsarevulnerabletomalicioussoftware.Thisarticlefirstbrieflydescribestheconceptofcomputernetworksecurity,andthenexpoundsthepresentsituationofcomputernetworksecurityandcommonsecuritythreats,andputsforwardcountermeasuresofnetworksecurityinviewoftheproblem.【Keywords】Thecomputernetworksecurity;Thestatusquo;Protectivecountermeasures目录一、引言................................................................................................................3二、计算机网络安全的概念与内容....................................................................3(一)网络安全的概念................................................................................3(二)网络安全的内容................................................................................3三、计算机网络安全的现状................................................................................4(一)技术方面的威胁................................................................................41、计算机病毒......................................................................................42、黒客攻击..........................................................................................5(二)管理方面的威胁................................................................................71、网络配置管理不当..........................................................................72、人为的无意失误..............................................................................73、人为的恶意攻击..............................................................................7四、计算机网络安全的防护对策........................................................................7(一)针对技术方面的威胁的防范措施....................................................71、病毒的防治......................................................................................72、黑客的防范......................................................................................83、网络系统结构的合理设计..............................................................94、防火墙控制....................................................................................105、加强数据加密技术........................................................................10(二)针对管理方面的威胁的防范措施..................................................111、网络安全管理措施........................................................................112...
