Configuring NACLs Using AWS

Securing an AWS Virtual Private Cloud (VPC) is an important cloud security skill. In this lab scenario, it's your responsibility to implement two network access control lists (NACLs) for the VPC's public and private subnets. By controlling network access of the two subnets, you can ensure that unused protocols are denied access to properly secure the VPC.
