【摘要】 网络发展日新月异，电子商务如火如荼，网络安全问题亦接踵而至，以信息技术的广泛应用，网络为平台的现代企业在充分享受网络与电子商务的便利与快捷时也需正视网络带来的相关问题，特别是安全！ 现代企业网络安全涉及到企业、网络技术、人员心理、社会大环境等许多方面的因素，对其进行分析时由于其中绝大多数的考虑因素都是极难量化表示的，如果只是通过简单的假设将其忽略或拟量化以适应某种定量方法的话，那么所建立的模型就无法按照实际问题的性质反映所有因素的作用。所以我们只能采用既能处理定量参数，又能考虑定性因素的方法来进行建模。 本文在充分界定现代企业及其数字化经济特质时，对其安全问题亦进行了较全面的研究与探讨，对现代企业网可能面临的网络风险、网络攻击进行了考察，并首次将层次分析、德尔菲法等传统的分析方法应用于网络及网络安全这一全新领域，为其建立了层次模型，从而使得网络安全与防护这一主要靠经验决策的问题有了更科学、更准确、更合理快捷的解决方法。 同时本文亦针对现代企业网的特点与安全要求，提出了一套系统、先进、科学合理的网络安全解决方案，涉及局域网安全解决方案、广域网安全解决方案、Internet互连安全解决方案以及操作系统安全、应用程序安全、防病毒、反黑客安全等解决方案。更多还原

【Abstract】 With the development of network and Electronic Commerce, networksecurity is becoming increasingly noticeable, While Modern Enterprises,based on network flatfOrm and widely applying InfOrmation Technology, arebenefited from the facility of network and Electronic Commerce, lots ofproblems fOllowing, especialIy network security, shouId be paid attentionto.Network security of Mod ern Enterprise dea] s with enterpri ses, networktechnologies, personnel psychology, the society and so on, most of whichare difficult to quantize. The model, ignoring simply or quantizingapproximateIy some factors to adapt to some quantitative methods, will notshow their exact roles in practice. TherefOre, the modeling methods, takingquantitative parameters and qualitative factors into account, should bead o ptedThe definition of Modern Enterprise and its digitaI economic characterare presented Its security is analyzed comprehensively, and then the riskand attack of network are studied Analytic Hierarchy Process (AHP) isfirstly applied to the fields of network and its security Modeling based onthe new method presents a reasonable solution, which is more scientific,accurate and convenient, to network security and prevention, most of whichwere decided by experience previously.Meanwhile, a systematic, advanced and scientific suit of solution tonetwork security is presented according with the properties and securitydemands of Modern Enterprise network, incIuding security soIutions toLAN, WAN and Internet, and those to Operation System, appl icationprogram, anti-virus and anti-hacker更多还原
