如何配置Cisco PIX防火墙
?任何企业安全策略的一个主要部分都是实现和维护防火墙，因而防火墙在网络安全的实现傍边扮演着主要的人物。防火墙一般坐落企业网络的边缘，这使得内部网络与Internet之间或许与其他外部网络相互阻隔，并限制网络互访从而维护企业内部网络。设置防火墙意图都是为了在内部网与外部网之间设立唯一的通道，简化网络的安全管理。(?A major part of any enterprise security strategy is implementing and maintaining firewalls, so firewalls play a major role in the implementation of network security. Firewalls are generally located at the edge of an enterprise network, which blocks the internal network and the Internet from other external networks, and restricts network access to maintain the internal network of the enterprise. The purpose of setting a firewall is to set up a unique channel between the internal network and the external network to simplify network security management.)
