Event Information

  1. The Microsoft.Sql.managedInstances.keys.delete event in Azure for AzureDatabaseService refers to the deletion of a key associated with a managed instance in Azure SQL Database.

  2. This event indicates that a key, which is used for authentication and encryption purposes, has been removed from the managed instance.

  3. It is important to monitor this event as it can help track any changes or potential security risks related to the keys used for accessing and securing the Azure SQL Database managed instance.

Examples

  1. Unauthorized deletion of managed instance keys: If security is impacted with Microsoft.Sql.managedInstances.keys.delete in Azure for Azure Database Service, it could potentially allow unauthorized individuals to delete the managed instance keys. This could lead to a loss of access control and compromise the security of the database service.

  2. Data loss or corruption: Deleting managed instance keys without proper authorization or backup procedures in place can result in data loss or corruption. If the keys are deleted, it may become impossible to access or recover the encrypted data stored in the Azure Database Service.

  3. Disruption of business operations: In the event of unauthorized deletion of managed instance keys, the Azure Database Service may become inaccessible, leading to a disruption of business operations. This can have significant financial and operational implications for organizations relying on the database service for their applications and services.

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 for Azure Storage:

    • Go to the Azure portal and navigate to the Azure Storage account.
    • Select the specific storage account you want to enable encryption for.
    • In the left-hand menu, under the Settings section, click on “Encryption”.
    • Enable the “Encryption at rest” option.
    • Choose the desired encryption type, such as Microsoft-managed keys or customer-managed keys.
    • Click on “Save” to apply the changes.
  3. Enable logging and monitoring for Azure Virtual Machines:

    • Go to the Azure portal and navigate to the Azure Virtual Machine.
    • Select the specific virtual machine you want to enable logging and monitoring for.
    • In the left-hand menu, under the Monitoring section, click on “Diagnostic settings”.
    • Click on “Add diagnostic setting” to create a new diagnostic setting.
    • Configure the desired diagnostic settings, such as enabling boot diagnostics, guest OS diagnostics, and performance counters.
    • Choose the desired destination for the logs, such as Azure Storage or Azure Event Hubs.
    • Click on “Save” to apply the changes.

Note: The above instructions are general guidelines and may vary depending on the specific Azure services and configurations you are working with. It is recommended to refer to the official Azure documentation for detailed instructions and best practices.

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 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.
