# aws\_vpcs
|
|
|
|
Use the `aws_vpcs` InSpec audit resource to test properties of some or all AWS Virtual Private Clouds (VPCs).
|
|
|
|
A VPC is a networking construct that provides an isolated environment. A VPC is contained in a geographic region, but spans availability zones in that region. A VPC may have multiple subnets, internet gateways, and other networking resources. Computing resources--such as EC2 instances--reside on subnets within the VPC.
|
|
|
|
Each VPC is uniquely identified by its VPC ID. In addition, each VPC has a non-unique CIDR IP Address range (such as 10.0.0.0/16) which it manages.
|
|
|
|
Every AWS account has at least one VPC, the "default" VPC, in every region.

## Syntax
|
|
|
|
An `aws_vpcs` resource block uses an optional filter to select a group of VPCs and then tests that group.
|
|
|
|
# The control will pass if the filter returns at least one result. Use `should_not` if you expect zero matches.
|
|
describe aws_vpcs do
|
|
it { should exist }
|
|
end
|
|
|
|
