Section 1: What Are Network Access Control Lists (NACLs)?
One such feature of security provided by AWS(Amazon Web Services) is the Network Access Control List(NACL). This NACL is defined by default for every Virtual Private Network(VPC). However, you can create custom NACL according to your requirements. These NACL define inbound and outbound rule for subnets present in VPC. These have almost the same function as Security Groups the only difference is NACL works in subnet levels and Security groups are defined for instances and other resources.
