Client Certificates Disabled

More Info:

Client certificates allow the app to request a certificate for incoming requests. Only clients with a valid certificate will be able to reach the application. The TLS mutual authentication technique in enterprise environments ensures the authenticity of clients to the server.

Using Console

Using CLI

To remediate the “Client Certificates Disabled” misconfiguration in Azure using Azure CLI, follow these steps:

Open the Azure CLI terminal and login to your Azure account.
Run the following command to list all the App Service Plans in your subscription:
```
az appservice plan list
```
Identify the App Service Plan that is affected by the misconfiguration.
Run the following command to enable client certificates for the App Service Plan:
```
az appservice plan update --name <app-service-plan-name> --resource-group <resource-group-name> --set clientCertEnabled=true
```
Replace <app-service-plan-name> with the name of the App Service Plan and <resource-group-name> with the name of the resource group that contains the App Service Plan.
Verify that client certificates are enabled for the App Service Plan by running the following command:
```
az appservice plan show --name <app-service-plan-name> --resource-group <resource-group-name> --query clientCertEnabled
```
This command should return true, indicating that client certificates are now enabled for the App Service Plan.
Repeat the above steps for any other affected App Service Plans in your subscription.

By following these steps, you should be able to remediate the “Client Certificates Disabled” misconfiguration in Azure using Azure CLI.

Using Python

To remediate the “Client Certificates Disabled” misconfiguration in Azure using Python, you can use the Azure SDK for Python. Follow these steps:

Install the Azure SDK for Python using pip:

pip install azure-mgmt-web

Authenticate with Azure using a Service Principal:

from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.web import WebSiteManagementClient

# Replace with your own values
subscription_id = 'your-subscription-id'
client_id = 'your-client-id'
secret = 'your-client-secret'
tenant = 'your-tenant-id'

# Create a Service Principal credential
credentials = ServicePrincipalCredentials(
    client_id=client_id,
    secret=secret,
    tenant=tenant
)

# Create a WebSiteManagementClient using the credentials
web_client = WebSiteManagementClient(credentials, subscription_id)

Get the App Service Plan resource group and name:

# Replace with your own values
resource_group_name = 'your-resource-group-name'
app_service_plan_name = 'your-app-service-plan-name'

# Get the App Service Plan
app_service_plan = web_client.app_service_plans.get(resource_group_name, app_service_plan_name)

Enable Client Certificates for the App Service Plan:

# Set the Client Certificates property to True
app_service_plan.client_cert_enabled = True

# Update the App Service Plan
web_client.app_service_plans.create_or_update(resource_group_name, app_service_plan_name, app_service_plan)

After running these steps, the “Client Certificates Disabled” misconfiguration should be remediated for the specified App Service Plan in Azure.
