防火墙的安全策略直接决定着防火墙使用效果的好坏。因此,东方龙马公司提出了分为四个网络接口的防火墙安全策略。此防火墙的安全目标就是保护内部网络的资源不受侵害。东方龙马将四个网络接口分別连接LAN(内部网)、DMZ(隔离区)、Control(控制区) 以及外部网.其中与外部网连接的是非安全网卡,其它为安全网卡。 LAN区内部网络是不对外开放的区域,它下对外提供任何服务,所以外部用户检测下到它的IP地址,也难以对它 Firewall security strategy directly determines the effectiveness of the use of the firewall. Therefore, Oriental Ryoma proposed a firewall security policy divided into four network interfaces. The security goal of this firewall is to protect the internal network resources from infringement. Eastern Ryoma will be four network interfaces were connected to LAN (internal network), DMZ (isolated area), Control (control area) and the external network which is connected with the external network is a non-secure network card, the other for the safety network card. LAN area network is not open to the outside world, it provides any external services, so the external user detection down to its IP address, it is difficult to it
