基于U盘下嵌入式Linux—iptables的防火墙设计与实现

Design and Implementation of Embedded Linux-IPtables Firewall Based on U-disk

在对现有防火墙技术分析的基础上,参加学校组织的《大学生创新性实验计划》项目的前提下,描述了一种基于嵌入式U盘Linux--iptables下的小型防火墙。网络管理员可以很方便地通过Linux启动计算机的U盘对其进行配置与管理。该系统具有很好稳定性与可扩展性,能很好地满足小型企业局域网的安全需求,并给出了基于U盘的防火墙的实现。

that at the basis of current firewall technology, this article describes a small firewall which based on embedded U disk Linux--iptables of firewaU.The network administrator can conveniently do the disposition and management through the Linux boot the computer with the U disc.The system has good stability and scalability, which can meet the demand of small enterprise LAN security.At the last paragraph, it shows the way to implement its function.
