Linux系统安全问题分析与研究

本文针对Linux本身所具有的良好安全机制,从不同角度阐述了如何设置才能更好地提高系统安全性。接着重点介绍了与Linux内核集成的iptables包过滤系统,在此基础上实现了一个简单的linux防火墙系统,经实际测试能够达到对外网防御内网保护的目的。

Security Analysis and Research in Linux System

Linux itself has a good security mechanism,this paper describes that how to improve the system security better by the reasonable settings from different angles. Then it highlights the iptables packet filtering system which is integrated with the system kernel,on this basis,it implements a simple Linux firewall system,the test results prove that the firewall system has some application values.
