Event Information

  • The Microsoft.DBforMariaDB.servers.databases.delete event in Azure for Azure Database Service indicates that a database has been deleted in a MariaDB server.
  • This event signifies that a specific database within the MariaDB server has been permanently removed and cannot be recovered.
  • It is important to note that this event does not delete the entire MariaDB server, but only a specific database within it.

​
Examples

  1. Unauthorized deletion: If security is impacted with Microsoft.DBforMariaDB.servers.databases.delete in Azure for Azure Database Service, one example could be an unauthorized user gaining access to the Azure portal or API and deleting a database without proper authorization. This could result in the loss of critical data and disrupt business operations.

  2. Lack of access controls: Another example could be the absence of proper access controls and permissions for the Microsoft.DBforMariaDB.servers.databases.delete operation. If users have excessive privileges or if there are no restrictions in place, it could lead to unauthorized individuals being able to delete databases, potentially causing data breaches or service disruptions.

  3. Insufficient logging and monitoring: A third example could be the lack of robust logging and monitoring mechanisms for the Microsoft.DBforMariaDB.servers.databases.delete operation. Without proper logging, it may be difficult to track and investigate any unauthorized deletions or malicious activities. Insufficient monitoring could also result in delayed detection of security incidents, allowing attackers to go undetected for longer periods.

Using Console

None

​
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 the Azure Database Service.
    • Create a Log Analytics workspace and configure it to collect and analyze logs from the database service.
    • Use the Azure Monitor Python SDK to programmatically create and manage alerts and log analytics queries.

  2. Implement automated backups and retention policies:

    • Use the Azure Python SDK to create a backup policy for your Azure Database Service.
    • Schedule automated backups using the SDK and set the desired retention period.
    • Implement a script that periodically checks the backup status and triggers backups if necessary.

  3. Implement security best practices:

    • Use the Azure Python SDK to configure firewall rules and network access control for your Azure Database Service.
    • Implement encryption at rest and in transit using the appropriate SDK methods.
    • Regularly rotate database access credentials and use Azure Key Vault to securely store and manage them.

Please note that providing specific Python scripts within the response is not feasible due to the character limitations. However, you can refer to the official Azure SDK for Python documentation and samples for detailed code examples and implementation guidance.
