What is an Access-Control List (ACL)?
An Access-Control List (ACL) is a list of rules that you can use to filter network traffic on devices that have filtering capabilities. These rules categorize packets, so that you can decide whether to allow or deny them. A standard ACL only lets you assess a packet's source IP address, while an extended ACL lets you access both the source and the destination address. The latter are more difficult to configure and more CPU intensive, but they can give you far more granular control over your traffic.
An ACL can provide better security for your network, by making it less vulnerable to dangerous and unwanted traffic. Often, you configure an ACL on an edge router facing the public Internet, as this can create a buffer between it and your private network.
It should be noted that you can use ACLs for purposes other than packet filtering, such as for network address translation (NAT) and for making quality of service (QoS) determinations.
