Security Policy ACLs help accurately identify and control packets on the network to manage network access behavior, prevent network attacks, and improve bandwidth use efficiency. An ACL is a collection of one or more rules. A rule refers to a judgment statement that describes a packet matching co...

Mistakes in ACL placement are some of the most common ones network administrators make during security implementation. Trust me, it happens to us all and I am not immune to that one. Figure 2 provides a good example of the traffic flow when it comes to ingress and egress on a router netw...
然后,我们看下第一个问题;我们需要先把ACL应用的对象(对路由器来说就是端口,对交换机来说就是vlan,对应在我们的实验目标就是vlan 40)是一个闸门; in和out就是对应的的详细解释可以理解为: in:我是vlan 40,数据从我这里(in)出去;(来自内部) out:我是vlan 40,数据从外面(out)进来;(来自外部) 这里有点绕...

A network ACL is an optional layer of protection for your subnets. After you add inbound and outbound rules to a network ACL and associate subnets with it, you can contro
