1. This week we open up discussing Access Control Lists(ACLs). These important list help to provide more control with routing updates or packets as they move throughout the network. They provide an extra layer of security to ensure traffic is controlled as it goes in and out of the router. Security is the number reason to use an ACL.
As packets come in or out the router, the ACL processes in a line by line form from top to bottom of the list. Each line is testing the packets to confirm a "match." If there is a match, a "permit" or "deny" rule is applied. When a "match" occurs, no further rules are checked.
Class, in your own words and based on what you have read, what happens if there is no match?
2. Chapter 26 talks about extended access control list (ACL). This form of an ACL provides higher control over how traffic is prioritized vs. standard ACLs that look solely at the source IP. Extended ACLs can use a variety of parameters from source/destination IP, to protocol and port. One thing to remember about extended ACLs is the placement and direction which is critically important.
Class, where should an extended ACLs be placed close to and why?
