用访问控制列表打造安全网络

To create the safe network by using the access control list

日常网络的管理中,经常会遇到一些进退两难的问题。如既要保障网络点畅通,同时,也必须设法拒绝那些不希望的网络连接。虽然可以通过其他的一些方式,如密码、权限、虚拟局域网等功能实现这些目的,但是,它们只能实现一些单一的管理功能,且缺乏管理的灵活性。而访问控制列表,则给网络管理员提供了一个灵活的网络控制平台。

In our daily management of network, we often meet some problems, which make us dilemma. For example, we not only ensure the smooth liquidity of network but also manage to turn off the unexpected network connection. Although we can use some methods to reach this aim, such as code, limitation ＆ the function of virtual local area network （VLAN）, these methods can still only provide some simple managing function, which are lack of flexibility of managing. So the access control list can provide us managers a flexible platform controlling the network.
