### Description{% #description %}

Kubernetes Engine clusters must have network policies enabled to restrict traffic between pods and control communication within the cluster. In Terraform, this requires setting `network_policy.enabled = true` and `addons_config.network_policy_config.disabled = false`, as shown below:

```
network_policy {
  enabled = true
}
addons_config {
  network_policy_config {
    disabled = false
  }
}
```

If these settings are not properly configured, unauthorized traffic between pods may be allowed, increasing the risk of lateral movement and potential compromise of sensitive applications or data within the cluster.

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

```terraform
#this code is a correct code for which the query should not find any result
resource "google_container_cluster" "negative1" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3
  network_policy {
      enabled = true
  }
  addons_config {
    network_policy_config {
        disabled = false
    }
  }
  networking_mode = "VPC_NATIVE"

  timeouts {
    create = "30m"
    update = "40m"
  }
}
```
