### Description{% #description %}

An ingress `nifcloud_security_group_rule` allows traffic from a `/0` CIDR. The policy detects `nifcloud_security_group_rule` resources whose `cidr_ip` is `/0` (allowing traffic from anywhere) and flags them as insecure. The rule reports the following attributes: `documentId`, `resourceType`, `resourceName`, `searchKey`, `issueType`, `keyExpectedValue`, and `keyActualValue`.

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
resource "nifcloud_security_group_rule" "negative" {
  security_group_names = ["http"]
  type                 = "IN"
  description          = "HTTP from VPC"
  from_port            = 80
  to_port              = 80
  protocol             = "TCP"
  cidr_ip              = "10.0.0.0/16"
}
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}
