论坛上的GG.JJ们,小第想往网络安全方面发展,但不想局限于网络工具的使用下的网络安全管理员，更想自己动手去写些补丁,找些漏洞,最后能开发属于自己的防火墙,当然这个是后画了，小弟有C JAVA的基础,该从哪个方面开始衍生,现在特别迷茫,所谓学习新的东西,没有方向是万万不可的,坛里有谁是做这方面的好给小弟指条道,小弟在这里先谢谢了!

I think you should choose JAVA.

java? is the java useful and universality ? what should i study first!

You should be familar with different kinds of network protocals.

Following specified packet format, analyse whether the packet should go through your firewall.

You probably have a understanding on many important ports. Why you open this port instead of another one.

Definitly, what a wide networking knowledge.

Suggest you work over cisco.

Just represent my own opinion.
