Remediation
To remediate the misconfiguration “Secure Boot Should Be Enabled For Kubernetes Node Pools” for GCP using GCP console, follow the below steps:
- Open the GCP console and navigate to the Kubernetes Engine page.
- Click on the name of the cluster for which you want to enable Secure Boot.
- Click on the “Nodes” tab and select the node pool for which you want to enable Secure Boot.
- Click on the “Edit” button at the top of the page.
- In the “Node pool details” section, scroll down to the “Security” section.
- Check the box next to “Enable secure boot”.
- Click on the “Save” button at the bottom of the page.
Once you have completed these steps, the Secure Boot will be enabled for the selected node pool of your Kubernetes cluster in GCP.
To remediate the misconfiguration “Secure Boot Should Be Enabled For Kubernetes Node Pools” for GCP using GCP CLI, you can follow the below steps:
-
Open the Cloud Shell in GCP Console.
-
Run the following command to get the list of node pools in your GKE cluster:
gcloud container node-pools list --cluster [CLUSTER_NAME] --zone [ZONE]
Replace [CLUSTER_NAME] with the name of your GKE cluster and [ZONE] with the zone in which your cluster is located.
-
For each node pool, run the following command to enable secure boot:
gcloud container node-pools update [NODE_POOL_NAME] --cluster [CLUSTER_NAME] --zone [ZONE] --security-config enable-secure-boot
Replace [NODE_POOL_NAME] with the name of the node pool.
-
Verify that secure boot is enabled for the node pool by running the following command:
gcloud container node-pools describe [NODE_POOL_NAME] --cluster [CLUSTER_NAME] --zone [ZONE] | grep secureBoot
If the output shows “secureBoot: true”, then secure boot is enabled for the node pool.
-
Repeat steps 3-4 for all the node pools in your GKE cluster.
By following these steps, you can remediate the misconfiguration “Secure Boot Should Be Enabled For Kubernetes Node Pools” for GCP using GCP CLI.
To remediate the misconfiguration “Secure Boot Should Be Enabled For Kubernetes Node Pools” for GCP using Python, you can follow these steps:
-
Install the Google Cloud SDK and Python client library for GCP.
-
Create a new Python script and import the necessary libraries:
import google.auth
from google.cloud import container_v1
- Authenticate with GCP using the following code:
credentials, project_id = google.auth.default()
client = container_v1.ClusterManagerClient(credentials=credentials)
- Get the list of node pools in your GCP project using the following code:
project_id = 'your-project-id'
zone = 'us-central1-a'
cluster_id = 'your-cluster-id'
response = client.list_node_pools(project_id, zone, cluster_id)
- For each node pool, check if Secure Boot is enabled. If it is not enabled, update the node pool with Secure Boot enabled using the following code:
for node_pool in response.node_pools:
if not node_pool.config.secure_boot:
node_pool.config.secure_boot = True
update_request = container_v1.types.UpdateNodePoolRequest(
project_id=project_id,
zone=zone,
cluster_id=cluster_id,
node_pool_id=node_pool.name,
node_pool=node_pool.config,
update_mask={'paths': ['config.secure_boot']}
)
client.update_node_pool(update_request)
- Save the Python script and run it to remediate the misconfiguration.
Note: Make sure to replace ‘your-project-id’, ‘us-central1-a’, and ‘your-cluster-id’ with your actual GCP project ID, zone, and cluster ID.
