A Primer on Access Control Lists in a Router

Access Control Lists (ACLs) are an essential and critical tool on a network. They allow traffic to be filtered and selected as it moves about the network. ACLs can be broken down into two main categories: standard and extended ACLs.

Standard ACLs only work on source IP addresses while extended ACLs can select data packets by protocol, source and destination IP addresses and ports to name a few. Once selected, the data can then be permitted or denied. Thanks to advances in hardware computing power, most ACLs tend to be the extended type, standard ACLs were more convenient when the hardware struggled to process large data on a network.

ACLs can become quite complex, proper planning and testing with tools like Wireshark for instance, will help identify gaps and issues to ensure successful implementation. Properly designed and tested ATLs are key components in the overall security toolbox for any network.
