Intranet Security and Firewalls Technology

针对Ｉｎｔｒａｎｅｔ上的安全问题，在分析现有的几种防火墙技术的结构和特点的基础上，讨论了Ｋｅｒ－ｂｅｒｏｓ身份认证协议，提出了一种结合Ｋｅｒｂｅｒｏｓ身份认证的防火墙结构．

In recent years, the scale of Intranet has risen up steadily. On the other side, however, it has also spawned an increasing number of opportunities for compromising the security of data and resources in the networking environment. Security situation on Intranet is becoming more and more serious. In the paper, the structures and features of several types of firewalls are discussed. In the authors opinion, only with the firewall is not enough. Thus Kerberos authentication protocol is presented, and a new firewall structure which is combined with authentication protocol is proposed at the end of the paper.
