An ACL is essentially a list of ALLOW or DENY rules that control access to your network. It's very basic; no dynamic protections or alerting, just traffic control for HTTP(S), TCP, RDP, MySQL, etc. Whenever you create a virtual machine/instance, you're also automatically creating a securitygroup, which acts as a virtual firewall at the instance level.

While subnets’ network access control list (NACL) can be used to further control traffic flow, in this project we leave them with the AWS default VPC behavior; an open NACL. All of the instances are associated with the security groups: project-egress: For outbound traffic, this security group allows any traffic to any destination, i.e., 0.0.0.0/0.

AWS security groups (SGs) are associated with EC2 instances and provide security at the protocol and port access level. Each security group — working much the same way as a firewall — contains a set of rules that filter traffic coming into and out of an EC2 instance. Unlike network access control lists (NACLs), there are no “Deny” rules.
