Using Console

Using CLI

To remediate the misconfiguration “SQL Database Servers Should Not Have Unrestricted Access” in Azure using Azure CLI, follow these steps:

Open the Azure CLI and login to your Azure account.
Identify the SQL Database Server that has unrestricted access by running the following command:
```
az sql server list
```
This will list all the SQL Database Servers in your Azure account.
Once you have identified the SQL Database Server, run the following command to update the firewall rules:
```
az sql server firewall-rule update --resource-group <resource-group-name> --server <server-name> --name AllowAllWindowsAzureIps --start-ip-address 0.0.0.0 --end-ip-address 0.0.0.0
```
This command will update the firewall rule named “AllowAllWindowsAzureIps” to restrict access to the SQL Database Server to only Azure services and resources.
Verify that the firewall rule has been updated by running the following command:
```
az sql server firewall-rule show --resource-group <resource-group-name> --server <server-name> --name AllowAllWindowsAzureIps
```
This command will show the details of the updated firewall rule.

By following these steps, you have successfully remediated the misconfiguration “SQL Database Servers Should Not Have Unrestricted Access” in Azure using Azure CLI.

Using Python

To remediate the misconfiguration “SQL Database Servers Should Not Have Unrestricted Access” in Azure using Python, you can use the following steps:

Import the necessary libraries and authenticate to Azure using the Azure SDK for Python.

from azure.identity import DefaultAzureCredential
from azure.mgmt.sql import SqlManagementClient
from azure.mgmt.resource import ResourceManagementClient

credential = DefaultAzureCredential()
subscription_id = '<your-subscription-id>'

resource_client = ResourceManagementClient(credential, subscription_id)
sql_client = SqlManagementClient(credential, subscription_id)

Retrieve the list of SQL servers in your subscription.

servers = sql_client.servers.list()

For each SQL server, check if it has any firewall rules that allow unrestricted access.

for server in servers:
    firewall_rules = sql_client.firewall_rules.list_by_server(server.resource_group, server.name)
    for rule in firewall_rules:
        if rule.start_ip_address == '0.0.0.0' and rule.end_ip_address == '255.255.255.255':
            # This firewall rule allows unrestricted access, so delete it
            sql_client.firewall_rules.delete(server.resource_group, server.name, rule.name)

Once all the firewall rules have been deleted, you can verify that the SQL servers no longer have unrestricted access.

for server in servers:
    firewall_rules = sql_client.firewall_rules.list_by_server(server.resource_group, server.name)
    for rule in firewall_rules:
        if rule.start_ip_address == '0.0.0.0' and rule.end_ip_address == '255.255.255.255':
            print(f"Server {server.name} still has a firewall rule that allows unrestricted access.")
        else:
            print(f"Server {server.name} has no firewall rules that allow unrestricted access.")

These steps will remediate the misconfiguration “SQL Database Servers Should Not Have Unrestricted Access” in Azure using Python.
