Event Information

  • The Microsoft.Sql.servers.databases.delete event in Azure for AzureDatabaseService refers to the deletion of a database within the SQL Server service in Azure.
  • This event indicates that a specific database has been permanently removed from the Azure SQL Server.
  • It is important to note that this event does not delete the entire SQL Server instance, but only the specified database within it.

​
Examples

  1. Unauthorized deletion: If security is impacted with Microsoft.Sql.servers.databases.delete in Azure for AzureDatabaseService, it could potentially allow unauthorized users to delete databases. This could lead to data loss and disruption of critical business operations.

  2. Data breach: If security is impacted, it could allow malicious actors to delete databases containing sensitive data. This could result in a data breach, where confidential information is exposed, leading to financial loss, reputational damage, and potential legal consequences.

  3. Service disruption: In case of a security impact, an unauthorized deletion of databases could cause service disruption for applications and users relying on those databases. This can result in downtime, loss of productivity, and financial implications for the organization.

Remediation

​
Using Console

  1. Enable auditing and threat detection:

    • Go to the Azure portal and navigate to the Azure SQL Database service.
    • Select the target database and click on “Auditing & Threat Detection” under the Security section.
    • Enable auditing by toggling the “Auditing” switch to “On” and configure the desired audit logs and storage account.
    • Enable threat detection by toggling the “Threat Detection” switch to “On” and configure the desired email notifications and storage account.

  2. Implement network security groups (NSGs):

    • Go to the Azure portal and navigate to the Azure SQL Database service.
    • Select the target database and click on “Firewalls and virtual networks” under the Security section.
    • Enable “Allow access to Azure services” to allow access from other Azure resources.
    • Configure NSGs to restrict inbound and outbound traffic to the database based on your specific requirements. For example, you can create an NSG rule to allow access only from specific IP addresses or subnets.

  3. Implement Azure Active Directory (Azure AD) authentication:

    • Go to the Azure portal and navigate to the Azure SQL Database service.
    • Select the target database and click on “Active Directory admin” under the Security section.
    • Enable Azure AD authentication by toggling the “Azure AD admin” switch to “On” and select the desired Azure AD tenant.
    • Assign appropriate Azure AD users or groups with the necessary permissions to access the database.

Note: The steps provided are general guidelines and may vary based on your specific Azure environment and requirements. It is recommended to refer to the official Azure documentation for detailed instructions.

Using CLI

To remediate issues related to Azure Database Service using Azure CLI, you can follow these steps:

  1. Enable auditing for Azure SQL Database:

    • Use the az sql server update-auditing command to enable auditing for the Azure SQL Server.
    • Specify the necessary parameters such as --state Enabled and --storage-account-resource-id to configure auditing settings.
    • Example command: az sql server update-auditing --resource-group <resource-group-name> --server <server-name> --state Enabled --storage-account-resource-id <storage-account-resource-id>

  2. Enable diagnostic settings for Azure SQL Database:

    • Use the az monitor diagnostic-settings create command to enable diagnostic settings for the Azure SQL Database.
    • Specify the necessary parameters such as --name, --resource-id, and --workspace to configure diagnostic settings.
    • Example command: az monitor diagnostic-settings create --name <diagnostic-settings-name> --resource <database-resource-id> --workspace <workspace-id>

  3. Enable threat detection for Azure SQL Database:

    • Use the az sql db threat-policy update command to enable threat detection for the Azure SQL Database.
    • Specify the necessary parameters such as --name, --resource-group, --server, and --state to configure threat detection settings.
    • Example command: az sql db threat-policy update --name <database-name> --resource-group <resource-group-name> --server <server-name> --state Enabled

​
Using Python

To remediate issues related to Azure Database Service using Python, you can follow these steps:

  1. Monitor and alert on database service events:

    • Use the Azure Monitor service to set up alerts for specific events or metrics related to your Azure Database Service.
    • Create an alert rule using the Azure SDK for Python to trigger an action when a specific event occurs.
    • Use the Azure Event Grid service to publish events to a topic and subscribe to those events using Python to take necessary actions.

  2. Automate database backups:

    • Use the Azure SDK for Python to create a script that automates the backup process for your Azure Database Service.
    • Set up a scheduled task or a cron job to run the script at regular intervals.
    • Ensure that the script includes error handling and logging to capture any issues during the backup process.

  3. Implement security best practices:

    • Use the Azure SDK for Python to configure firewall rules and virtual network service endpoints to restrict access to your Azure Database Service.
    • Enable auditing and threat detection for your database service using the Azure SDK for Python to detect and respond to potential security threats.
    • Regularly review and update the access control policies for your Azure Database Service using Python scripts to ensure compliance with security standards.

Please note that the provided examples are conceptual and may require customization based on your specific requirements and the Azure Database Service you are using.
