Event Information

  1. The Microsoft.Sql.managedInstances.administrators.delete event in Azure for AzureDatabaseService indicates that a deletion operation has been performed on the administrators of a managed instance in Azure SQL Database.

  2. This event signifies that one or more administrators have been removed from the managed instance, potentially impacting their access and permissions within the database service.

  3. It is important to monitor and track this event to ensure that any changes to the administrators of the managed instance are authorized and aligned with the security and compliance requirements of the Azure SQL Database environment.

​
Examples

  1. Unauthorized deletion of managed instance administrators: If security is impacted with Microsoft.Sql.managedInstances.administrators.delete in Azure for AzureDatabaseService, it could potentially allow unauthorized individuals to delete managed instance administrators. This could lead to a loss of control over the database service and compromise the security of sensitive data stored within it.

  2. Privilege escalation: The ability to delete managed instance administrators could be exploited by attackers to escalate their privileges within the Azure Database Service. By deleting existing administrators, an attacker could gain unauthorized access to sensitive data or perform malicious actions within the database.

  3. Disruption of administrative access: Deleting managed instance administrators could result in a disruption of administrative access to the Azure Database Service. This could impact the ability of authorized personnel to manage and maintain the database service, potentially leading to operational issues and downtime.

Remediation

​
Using Console

To remediate the issues for Azure Database Service using the Azure console, you can follow these step-by-step instructions:

  1. Enable auditing for Azure SQL Database:

    • Go to the Azure portal and navigate to the Azure SQL Database service.
    • Select the specific database you want to enable auditing for.
    • In the left-hand menu, under the Security section, click on “Auditing”.
    • Click on “Enable” to enable auditing for the database.
    • Configure the desired audit settings, such as storage account, retention period, and events to audit.
    • Click on “Save” to apply the changes.

  2. Enable encryption at rest for Azure SQL Database:

    • Go to the Azure portal and navigate to the Azure SQL Database service.
    • Select the specific database you want to enable encryption for.
    • In the left-hand menu, under the Security section, click on “Transparent data encryption”.
    • Click on “Enable” to enable encryption at rest for the database.
    • Wait for the encryption process to complete, which may take some time depending on the database size.
    • Once the encryption is enabled, the status will change to “Enabled”.

  3. Enable Azure Security Center recommendations:

    • Go to the Azure portal and navigate to the Azure Security Center.
    • In the left-hand menu, click on “Recommendations”.
    • Review the list of recommendations provided by Azure Security Center for your Azure resources.
    • Locate the recommendations related to Azure Database Service and click on them to view the details.
    • Follow the recommended steps provided by Azure Security Center to remediate the identified issues.
    • Once the remediation steps are completed, the recommendation status will change to “Remediated”.

Please note that the specific steps may vary slightly depending on the Azure portal version and interface changes. Always refer to the official Azure documentation for the most up-to-date 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.
