### Description{% #description %}

Google Cloud Dataproc clusters with public IP addresses are directly accessible from the internet, creating an expanded attack surface that could be exploited by malicious actors. When `internal_ip_only` is set to `false` or omitted, clusters receive both internal and external IP addresses, potentially exposing sensitive data processing operations and administrative interfaces to unauthorized access.

Secure configuration requires setting `internal_ip_only` to true as shown in this example:

```terraform
resource "google_dataproc_cluster" "good_example" {
  cluster_config {
    gce_cluster_config {
      internal_ip_only = true
    }
  }
}
```

The following is an insecure configuration that should be avoided:

```terraform
resource "google_dataproc_cluster" "bad_example" {
  cluster_config {
    gce_cluster_config {
      internal_ip_only = false
    }
  }
}
```

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

```terraform
resource "google_dataproc_cluster" "good_example" {
  name   = "good-cluster"
  region = "us-central1"

  cluster_config {
    gce_cluster_config {
      internal_ip_only = true # ✅ Private cluster (no public IP)
    }
  }
}
```

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

```terraform
resource "google_dataproc_cluster" "bad_example" {
  name   = "bad-cluster"
  region = "us-central1"

  cluster_config {
    gce_cluster_config {
      internal_ip_only = false # ❌ Public IP enabled
    }
  }
}
```
