文档介绍：中文摘要摘要信息化是现代企业从事日常生产经营活动和参与国内外市场并获得竞争优势必不可少的手段,计算机网络系统是支撑企业内外部各种信息传输、交互和共享的基本环境。由于网络的互联性、开放性和网络系统本身的漏洞和缺欠, 企业网每时每刻都面临来自内外部的威胁和攻击;企业网络结构各异、网络安全技术复杂、安全产品多样,所以如何设计和配置适合企业需求的网络安全方案是急需解决的技术难题。本文作者根据多年来从事企业信息化建设和网络管理实践,针对东风朝柴计算机网络结构和存在的各种安全隐患,通过对计算机防病毒、防火墙、入侵检测、数据自动备份与容灾等各种安全技术和理论的分析研究,归纳总结出了全网动态安全体系模型=风险分析+制定策略+防御系统+实时检测+实时响应,得出了建立整体的、多层次的、全方位的网络安全模式是企业网络安全的有效方法。本文遵照网络安全设计原则,在充分考察和调研的基础上通过选择合适的网络产品设计出了先进、科学、合理的网络安全方案。本文另一个观点是,企业网络安全是技术和管理的综合,网络安全离不开必要的技术手段,但针对企业网络系统具体应用特点建立和完善各种管理制度十分必要。该设计方案已在东风朝柴计算机网络实际中得到应用,较好的解决了企业网络安全问题。本文对解决目前大型企业网络安全技术问题具有重要指导意义。关键词:网络安全,防病毒,防火墙,入侵检测,数据备份与容灾 Al 垒!!!!!!也!!g!些——一一 Abstract Informatization is an essential means formodem enterprises tobeengaged indaily production and intoboth domestic and overseas markets and petition work system isthe basic environment that supporfs enterpdse municating,interacting and work interconnectivity,openness and itsin-house inconsistencies and defects。 work are facing threatens and a垃acks both internaland external minutely With the different work structures,work security technology and the diversified security products,it isinurgent need tosolve the technical problem ofhow todesign and work and data security solution meeting enterprise needs According tomulti—year practice intheconstruction ofenterprise informatization work author propose thattosetup an integrated,multi—level and all—work security mode should be theefficientway work and data ismade byfocusing on work structure ofDongfeng Chaoyang Diesel Co.,Ltd.(DCD forshorf)and the various incipient faults,and by analyzing and studying differentsecudty technologies and theories puter anti-virus,firewall,intrusion inspection,automatic data backup and disaster recovery.
