Event Information

  • The Microsoft.Sql.managedInstances.keys.read event in Azure for AzureDatabaseService refers to the action of reading the keys associated with a managed instance in Azure SQL Database.
  • This event is triggered when a user or application retrieves the keys required to establish a secure connection to the managed instance.
  • It is important to monitor this event as it provides visibility into the access and usage of the keys, which are crucial for securing the connection to the managed instance.

​
Examples

  1. Unauthorized access to sensitive data: If security is impacted with Microsoft.Sql.managedInstances.keys.read in Azure for AzureDatabaseService, it could potentially allow unauthorized users to read the encryption keys for managed instances. This could lead to unauthorized access to sensitive data stored in the database, compromising the confidentiality and integrity of the data.

  2. Data breaches and compliance violations: If encryption keys are accessed by unauthorized users, it could result in data breaches and compliance violations. Organizations may be subject to legal and regulatory requirements to protect sensitive data, and unauthorized access to encryption keys could lead to non-compliance and potential penalties.

  3. Compromised system integrity: If encryption keys are read by unauthorized users, it could also compromise the integrity of the system. Attackers could potentially modify or tamper with the encryption keys, leading to data corruption or unauthorized modifications to the database. This could impact the availability and reliability of the Azure Database Service.

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 Database Service.
    • Select the specific recommendation you want to remediate.
    • Follow the provided guidance and instructions to remediate the recommendation.
    • Once the remediation steps are completed, mark the recommendation as resolved in Azure Security Center.

Note: 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.
