1. Open the GCP console and go to the “IAM & Admin” section.
2. Click on “Roles” and search for the “Compute Load Balancer Admin” role.
3. Click on the “Compute Load Balancer Admin” role and then click on the “Edit” button.
4. Scroll down to the “Permissions” section and click on the “Add Permissions” button.
5. In the search bar, type “compute.targetPools.create” and select the checkbox next to it.
6. Repeat the same process for “compute.forwardingRules.create” and “compute.globalForwardingRules.create”.
7. Click on the “Save” button to apply the changes.

​

1. Open the GCP Cloud Shell or any terminal with GCP CLI installed, and authenticate with your GCP account using the following command:

gcloud auth login

2. Set the project in which you want to remediate the misconfiguration using the following command:

gcloud config set project PROJECT_ID

3. Run the following command to create a custom IAM role that restricts the creation of Load Balancers based on their types:

gcloud iam roles create RestrictLBType --project=PROJECT_ID --title="Restrict Load Balancer Creation Based on Type" --description="Restricts the creation of Load Balancers based on their types" --permissions=compute.backendBuckets.create,compute.forwardingRules.create,compute.globalForwardingRules.create,compute.targetHttpProxies.create,compute.targetHttpsProxies.create,compute.urlMaps.create,compute.targetPools.create

4. Run the following command to grant the custom IAM role to the users or groups that are allowed to create Load Balancers:

gcloud projects add-iam-policy-binding PROJECT_ID --member=USER_OR_GROUP --role=projects/PROJECT_ID/roles/RestrictLBType

5. Verify that the IAM policy binding has been added successfully using the following command:

gcloud projects get-iam-policy PROJECT_ID

1. First, you need to create a GCP service account with the required permissions to manage load balancers. You can do this by following the documentation here: https://cloud.google.com/iam/docs/creating-managing-service-accounts
2. Then, you need to install the Google Cloud SDK and the Python client library for GCP. You can follow the instructions here: https://cloud.google.com/sdk/docs/install and here: https://cloud.google.com/python/docs/reference
3. Next, you need to write a Python script that will check the load balancer type before creating a new load balancer. You can use the GCP Python client library to list the existing load balancers and check their types.
4. Here’s some sample code that you can use as a starting point:

from google.cloud import compute_v1

# Create a client object for the Compute Engine API
client = compute_v1.LoadBalancerClient()

# Define the allowed load balancer types
allowed_types = ['INTERNAL', 'HTTP', 'HTTPS']

# List the existing load balancers
load_balancers = client.list()

# Check the type of each load balancer
for lb in load_balancers:
    if lb.load_balancer_type not in allowed_types:
        # Delete the load balancer if it's not an allowed type
        client.delete(lb.self_link)

5. Finally, you can schedule this script to run periodically using a cron job or a similar tool. This will ensure that any load balancers that violate your policy are automatically deleted.

resource "google_org_policy_policy" "restrict_lb_types" {
  name   = "organizations/ORGANIZATION_ID/policies/compute.restrictLoadBalancerCreationForTypes"
  parent = "organizations/ORGANIZATION_ID" # Replace ORGANIZATION_ID with your numeric org ID

  spec {
    rules {
      # Replace the allowed_values below with the exact load balancer
      # types you want to permit. All other types will be blocked.
      #
      # Valid values include (check current docs for full list):
      #   "INTERNAL"
      #   "EXTERNAL"
      #   "INTERNAL_TCP_UDP"
      #   "INTERNAL_MANAGED"
      #   "EXTERNAL_MANAGED"
      #   "EXTERNAL_TCP_UDP"
      #   "EXTERNAL_NETWORK_TCP_UDP"
      list_policy {
        allow {
          values = [
            "ALLOWED_LB_TYPE_1",
            "ALLOWED_LB_TYPE_2",
          ]
        }
      }
    }

    inherit_from_parent = false
    reset = false
  }
}

• ORGANIZATION_ID with your GCP organization numeric ID.
• ALLOWED_LB_TYPE_1, ALLOWED_LB_TYPE_2 with the exact load balancer types your policy should allow.
