Event Information

  • The Microsoft.Sql.servers.databases.write event in Azure for AzureDatabaseService refers to a write operation performed on a database within the Azure SQL Server.
  • This event indicates that data has been modified or inserted into the specified database.
  • It is important to monitor this event as it helps track changes made to the database and can be useful for auditing, troubleshooting, and ensuring data integrity.

​
Examples

  1. Unauthorized access: If security is impacted with Microsoft.Sql.servers.databases.write in Azure for AzureDatabaseService, it could potentially allow unauthorized users to write or modify data in the Azure SQL Database. This could lead to data breaches, data loss, or unauthorized changes to critical database records.

  2. Data leakage: If security is impacted with Microsoft.Sql.servers.databases.write, it could result in data leakage where sensitive information stored in the Azure SQL Database is exposed to unauthorized individuals. This could occur if the write permissions are misconfigured or if there are vulnerabilities in the Azure platform that allow unauthorized access to the database.

  3. Malicious code injection: If security is impacted with Microsoft.Sql.servers.databases.write, it could enable attackers to inject malicious code into the Azure SQL Database. This could lead to the execution of unauthorized commands, data manipulation, or even complete compromise of the database. It is crucial to ensure that proper security measures are in place to prevent such code injection attacks.

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 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. 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 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.
