Linux新型内核防火墙研究和应用

The research and implementation of a new kernel firewall on Linux

在Linux新型防火墙netfilter框架原理及工作机制基础上,研究了该防火墙的应用设计,提出了用netfilter/iptables构建门户服务器防火墙的实现方法,实验测试证明,该防火墙能有效地阻止恶意攻击,提高了门户服务器的安全性。

Based on a new Linux netfilter firewall framework of principles and working mechanism, studied the application of the firewall design, then proposed a method of using netfilter / iptables to construct a portal server firewall, at last the experiment of testing showed that this firewall can effectively prevent malicious attacks, Enhance the security of the portal server.
