Using Console

Using CLI

To remediate the misconfiguration “Cloud CDN Regional Backend Services Should Have Session Affinity” in GCP using GCP CLI, please follow the below steps:

Open the Cloud Shell in your GCP console.
Run the following command to list all the backend services:
```
gcloud compute backend-services list
```
Choose the backend service that you want to enable session affinity for and note down its name.
Run the following command to enable session affinity for the chosen backend service:
```
gcloud compute backend-services update [BACKEND_SERVICE_NAME] --session-affinity CLIENT_IP
```
Note: Replace [BACKEND_SERVICE_NAME] with the name of your backend service.
Verify that session affinity is enabled for the backend service by running the following command:
```
gcloud compute backend-services describe [BACKEND_SERVICE_NAME] | grep sessionAffinity
```
The output should show “sessionAffinity: CLIENT_IP”. With these steps, you have successfully remediated the misconfiguration “Cloud CDN Regional Backend Services Should Have Session Affinity” in GCP using GCP CLI.

Using Python

To remediate the misconfiguration of Cloud CDN Regional Backend Services Should Have Session Affinity for GCP using Python, you can follow the below steps:

Open the Cloud Console and go to the Cloud CDN page.
Select the CDN resource that you want to remediate.
In the left navigation menu, select the Backend services option.
Select the backend service that you want to remediate.
In the left navigation menu, select the Session affinity option.
Select the option Enable session affinity.
Click Save to apply the changes.

To perform these steps programmatically using Python, you can use the Google Cloud Client Library for Python. Here’s an example code snippet:

from google.cloud import compute_v1

# Replace [PROJECT_ID], [REGION], and [BACKEND_SERVICE_NAME] with the appropriate values
project_id = '[PROJECT_ID]'
region = '[REGION]'
backend_service_name = '[BACKEND_SERVICE_NAME]'

# Create the client object
client = compute_v1.BackendServicesClient()

# Get the backend service object
backend_service = client.get(project=project_id, region=region, backend_service=backend_service_name)

# Enable session affinity
backend_service.session_affinity = compute_v1.BackendServiceSessionAffinity.CLIENT_IP

# Update the backend service
update_mask = compute_v1.field_mask.FieldMask(paths=['session_affinity'])
response = client.update(project=project_id, region=region, backend_service=backend_service_name, backend_service_resource=backend_service, update_mask=update_mask)

This code snippet uses the Google Cloud Client Library for Python to get the backend service object, enable session affinity, and update the backend service. Replace the placeholders [PROJECT_ID], [REGION], and [BACKEND_SERVICE_NAME] with the appropriate values for your environment.
