K8s secure boot remediation

Using Console

Using CLI

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.

Using Python

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.
