摘要
针对目前Internet互联网表现的脆弱性,从计算机网络安全策略出发,对解决计算机网络安全问题及网络的安全技术进行了研究,提出了分级防火墙体系结构.该结构将网络系统分为外部网和内部网,分设主级防火墙、次级防火墙及多级防火墙,克服了"个人防火墙"不能用于网络整体防护,分布式防火墙难于实施内部网全局策略统一的不足,立足全局策略,分级细化设防,进而提高网络系统安全与效率.
As for the work side of recent Internet, this paper discusses the security question and security technology of Internet, and put forward the firewall hiberarchy. This hierarchy divides the Network into Internal Network and external Network, and equips with primary firewall, secondary firewall and multistage firewall. So the shortage such as personal firewall can′t use in whole protection, distribute firewall has difficulty in realize Internal Network strategy may be overcome. The protection based on whole strategy can enhance the security and efficiency of Network system.
