Event Information

  1. The Microsoft.Sql.managedInstances.administrators.write event in Azure for AzureDatabaseService refers to a write operation performed on the administrators of a managed instance in Azure SQL Database.

  2. This event indicates that a change has been made to the list of administrators who have administrative privileges over the managed instance.

  3. It could involve adding, removing, or modifying the permissions of administrators, allowing them to perform administrative tasks such as managing databases, configuring security settings, or monitoring performance.

​
Examples

  1. Unauthorized access: If security is impacted with Microsoft.Sql.managedInstances.administrators.write in Azure for AzureDatabaseService, it could potentially allow unauthorized users to gain administrative access to the managed instance. This can lead to unauthorized modifications, data breaches, or even complete data loss.

  2. Privilege escalation: The Microsoft.Sql.managedInstances.administrators.write permission allows users to modify the list of administrators for the managed instance. If security is compromised, an attacker could escalate their privileges by adding themselves or other unauthorized users as administrators, granting them unrestricted access to the database service.

  3. Data manipulation or deletion: With the Microsoft.Sql.managedInstances.administrators.write permission, an attacker could potentially modify or delete critical data within the managed instance. This can result in data corruption, loss of sensitive information, or disruption of business operations. It is crucial to ensure that only authorized and trusted individuals have this permission to mitigate the risk of such security incidents.

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.

  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 recommendations provided by Azure Security Center for Azure Database Service.
    • Select the specific recommendation you want to remediate.
    • Follow the provided guidance and instructions to remediate the recommendation.
    • Once remediated, 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 Database for PostgreSQL:

    • Use the az postgres server update command to enable diagnostic settings for the Azure Database for PostgreSQL.
    • Specify the necessary parameters such as --name, --resource-group, and --logs to configure diagnostic settings.
    • Example command: az postgres server update --name <server-name> --resource-group <resource-group-name> --logs <log-categories>

  3. Enable encryption for Azure Cosmos DB:

    • Use the az cosmosdb update command to enable encryption for Azure Cosmos DB.
    • Specify the necessary parameters such as --name, --resource-group, and --enable-encryption to configure encryption settings.
    • Example command: az cosmosdb update --name <cosmosdb-account-name> --resource-group <resource-group-name> --enable-encryption true

Please note that the actual command parameters may vary based on your specific Azure environment and requirements. Make sure to replace the placeholders <resource-group-name>, <server-name>, <storage-account-resource-id>, <log-categories>, and <cosmosdb-account-name> with the appropriate values.

​
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.
