Description

The nifcloud_elb is configured to use the shared private network net-COMMON_PRIVATE. This exposes the private side to the shared network and should instead use a dedicated private LAN to maintain isolation. The rule flags any nifcloud_elb where network_interface.network_id equals net-COMMON_PRIVATE.

Compliant Code Examples

resource "nifcloud_elb" "negative" {
  availability_zone = "east-11"
  instance_port     = 80
  protocol          = "HTTP"
  lb_port           = 80
  network_interface {
    network_id = nifcloud_private_lan.main.id
  }
}

Non-Compliant Code Examples

resource "nifcloud_elb" "positive" {
  availability_zone = "east-11"
  instance_port     = 80
  protocol          = "HTTP"
  lb_port           = 80
  network_interface {
    network_id = "net-COMMON_PRIVATE"
  }
}

resource "nifcloud_elb" "positive" {
  availability_zone = "east-11"
  instance_port     = 80
  protocol          = "HTTP"
  lb_port           = 80
  network_interface {
    network_id = "net-COMMON_GLOBAL"
  }
  network_interface {
    network_id = "net-COMMON_PRIVATE"
  }
}
