What CGPulse checks
A resource passes this rule when state must equal available. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Verify NAT gateway is in available state; if failed, recreate in a public subnet with a valid Elastic IP. In AWS Console: VPC > NAT gateways > check state. See: https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html
Terraform
resource "aws_nat_gateway" "{name}" {
allocation_id = aws_eip.{name}.id
subnet_id = aws_subnet.public.id
}
