Description

A virtual private cloud (VPC) is a private virtual network in your AWS account, which is logically isolated from other virtual networks in AWS cloud. A VPC subnet is a subdivision of the VPC network, which has a range of IP addresses. A VPC subnet can be private or public, meaning that the IP addresses within the subnet are private or public. It was found that the subnet {AwsSubnet} automatically assigns public IPv4 to instances at launch, which might expose your resources to the internet.
