Event Information

  • The Microsoft.Sql.locations.instanceFailoverGroups.delete event in Azure for AzureDatabaseService indicates that an instance failover group has been deleted in the Azure SQL Database service.
  • This event typically occurs when an administrator or automated process initiates the deletion of an instance failover group.
  • Deleting an instance failover group removes the group’s configuration and any associated databases, and it prevents failover operations from being performed within the group.

​
Examples

  1. Unauthorized deletion: If security is impacted with Microsoft.Sql.locations.instanceFailoverGroups.delete in Azure for AzureDatabaseService, one example could be an unauthorized user gaining access to the Azure portal or API and deleting the failover group. This could result in the loss of high availability and potential data loss if the failover group was not properly backed up.

  2. Misconfiguration: Another example could be a misconfiguration of access controls or permissions within Azure. If the necessary RBAC roles or resource permissions are not properly configured, it could allow unauthorized users to delete the failover group, impacting the security of the Azure Database Service.

  3. Insider threat: A third example could be an insider threat scenario where a privileged user with legitimate access to the Azure environment intentionally deletes the failover group. This could be due to malicious intent or unauthorized actions by a disgruntled employee, resulting in a security breach and potential disruption to 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 network security groups for Azure Virtual Machines:

    • Go to the Azure portal and navigate to the Azure Virtual Machine service.
    • Select the specific virtual machine you want to apply network security groups to.
    • In the left-hand menu, under the Settings section, click on “Networking”.
    • Click on “Network security group” and then “Create new” to create a new network security group.
    • Configure the desired inbound and outbound rules to restrict network traffic.
    • Associate the newly created network security group with the virtual machine.
    • Click on “Save” to apply the changes.

Note: The above instructions provide a general overview of the steps involved in remediating the mentioned issues. It is important to consider your specific requirements and configurations while implementing these steps.

​
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 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 Backup service to schedule automated backups for your Azure Database Service.
    • Configure the retention policies to retain backups for a specific duration.
    • Utilize the Azure Python SDK to programmatically create and manage backup policies and retention settings.

  3. Implement security best practices:

    • Enable firewall rules to restrict access to your Azure Database Service.
    • Implement Azure Active Directory authentication for better security.
    • Utilize the Azure Key Vault service to securely store and manage database connection strings and credentials.
    • Use the Azure Python SDK to automate the configuration of firewall rules, enable Azure AD authentication, and interact with Azure Key Vault.

Please note that the provided steps are high-level guidelines, and the actual implementation may vary based on your specific requirements and the Azure Database Service you are using.
