At what level do network access control list provide protection?

Is an ACL the same as a firewall?

A firewall has one main use and purpose and that is to examine traffic passing through a part of the network and make decisions about what to let through and what to block. ACLs do stateless inspection, which means that the access list looks at a packet and has no knowledge of what has come before it.

What is NACL security?

A network access control list (NACL) is an optional layer of security for your VPC that acts as a firewall for controlling traffic in and out of one or more subnets. You might set up network ACLs with rules similar to your security groups in order to add an additional layer of security to your VPC.
