Concepts
1. Utilize Azure Active Directory authentication:
Azure SQL Database supports Azure Active Directory (Azure AD) authentication, which provides a secure alternative to SQL Server authentication. By using Azure AD, you can manage and authenticate users centrally, while also leveraging multi-factor authentication for enhanced security.
To enable Azure AD authentication for your Azure SQL Database, you can follow these steps:
- Open Azure Portal and navigate to your Azure SQL Database instance.
- In the left-hand menu, click on "Active Directory admin" under the Security section.
- Choose the Azure AD user or group that you want to grant access to the database.
- Click "Save" to apply the changes.
2. Implement firewall rules:
Azure SQL Database allows you to define firewall rules to control access to your SQL Server. By default, Azure SQL Database denies access to all IP addresses, including your own client IP address. You need to configure firewall rules to explicitly allow access.
To configure firewall rules for your Azure SQL Database, you can follow these steps:
- Open Azure Portal and navigate to your Azure SQL Database instance.
- In the left-hand menu, click on "Firewalls and virtual networks" under the Security section.
- Add the IP addresses or IP ranges that you want to allow access to the SQL Server.
- Click "Save" to apply the changes.
3. Enable virtual network service endpoints:
Azure SQL Database supports virtual network service endpoints, which allow you to secure access to your SQL Server by allowing connections only from selected virtual networks or subnets. This helps to protect your database from public internet access.
To enable virtual network service endpoints for your Azure SQL Database, you can follow these steps:
- Open Azure Portal and navigate to your Azure SQL Database instance.
- In the left-hand menu, click on "Firewalls and virtual networks" under the Security section.
- Click on "Add existing virtual network service endpoints" and select the virtual networks or subnets that you want to allow access.
- Click "Save" to apply the changes.
4. Use managed private endpoints:
Azure SQL Database also supports managed private endpoints, which enable you to access your SQL Server over a private connection within an Azure Virtual Network. This ensures that data traffic between your application and the SQL Server remains within the Microsoft Azure backbone network, providing enhanced security and isolation.
To create a managed private endpoint for your Azure SQL Database, you can follow these steps:
- Open Azure Portal and navigate to your Azure SQL Database instance.
- In the left-hand menu, click on "Private endpoint connections" under the Security section.
- Click on "Add" to create a new private endpoint connection.
- Specify the virtual network, subnet, and private DNS zone settings for the private endpoint.
- Click "OK" to create the private endpoint connection.
By following these steps, you can configure secure access for your Administering Microsoft Azure SQL Solutions. Remember to implement Azure AD authentication, firewall rules, virtual network service endpoints, and managed private endpoints to enhance the security of your Azure SQL Database.

Great article on configuring secure access for Azure SQL solutions!
This guide is very helpful, thanks!
How do you configure firewall rules in Azure SQL to restrict IP addresses?
You can go to the Azure portal, navigate to your SQL server, and then use the ‘Firewalls and virtual networks’ option to add the IP addresses you want to allow.
Don’t forget to allow Azure services to access the server if you are using other Azure resources!
Can someone explain the use of Private Endpoints in securing Azure SQL?
Private Endpoints allow you to connect to Azure SQL Database via an Azure private IP address, effectively keeping the traffic within the Azure network and not exposing it to the public internet.
It’s a great way to increase security, especially for compliance requirements!
Appreciate the detailed steps!
Awesome documentation, thank you!
Can we use Azure AD Authentication for Azure SQL Database?
Yes, Azure AD Authentication is supported and recommended because it allows you to manage database access centrally via Azure Active Directory.
I agree, it’s much more secure than SQL authentication!
Very informative, thanks!
