Event Information

  • The Microsoft.Sql.managedInstances.databases.write event in Azure for AzureDatabaseService refers to a write operation performed on a database within a managed instance in Azure SQL Database.
  • This event indicates that data has been modified or inserted into the specified database.
  • It is important to monitor this event to track changes made to the database and ensure data integrity and compliance with any relevant regulations or policies.

​
Examples

  1. Unauthorized write access: If security is impacted with Microsoft.Sql.managedInstances.databases.write in Azure for AzureDatabaseService, it could mean that unauthorized users or applications have the ability to write data to the managed instances databases. This can lead to data breaches, data corruption, or unauthorized modifications to critical data.

  2. Data leakage: Another security impact could be the potential for data leakage. If unauthorized write access is granted to the managed instances databases, sensitive or confidential data could be written to the databases by unauthorized users or applications. This can result in the exposure of sensitive information to unauthorized parties, leading to compliance violations and reputational damage.

  3. Malicious code execution: Granting write access to the managed instances databases without proper security controls can also increase the risk of executing malicious code. If an attacker gains unauthorized write access, they may be able to inject malicious code into the databases, which can lead to further compromise of the system, unauthorized access to other resources, or disruption of services. It is crucial to ensure that only authorized and trusted entities have the necessary write permissions to the managed instances databases.

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 for Azure App Service:

    • Go to the Azure portal and navigate to the Azure App Service.
    • Select the specific app service you want to enable logging 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.
    • Provide a name for the diagnostic setting and select the desired logs and metrics to enable.
    • 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 slightly depending on the specific Azure services and console versions you are using. It is always recommended to refer to the official Azure documentation for detailed and 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.
    • Example command: az sql server update-auditing --resource-group <resource_group_name> --server <server_name> --state Enabled --storage-account <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 --logs to configure diagnostic settings.
    • Example command: az monitor diagnostic-settings create --name <diagnostic_settings_name> --resource <database_resource_id> --logs '[{"category": "SQLSecurityAuditEvents", "enabled": true}]'

  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, and --storage-account to configure threat detection.
    • Example command: az sql db threat-policy update --name <database_name> --resource-group <resource_group_name> --storage-account <storage_account_resource_id> --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.
