Microsoft.storage.storageaccounts.queueservices.queues.write remediation

​

Event Information

1. The Microsoft.Storage.storageAccounts.queueServices.queues.write event in Azure for Azure Storage refers to a write operation performed on a queue within a storage account.
2. This event indicates that a message or data has been added to a queue in Azure Storage.
3. It can be used to track and monitor the activity and usage of queues in Azure Storage, providing insights into the volume and frequency of write operations.

​

Examples

1. Unauthorized access: If security is impacted with Microsoft.Storage.storageAccounts.queueServices.queues.write in Azure for AzureStorage, it could indicate that there is unauthorized access to write operations on the queues. This could potentially allow an attacker to modify or delete messages in the queue, leading to data loss or manipulation.
2. Data leakage: Another security impact could be the potential for data leakage. If unauthorized write access is granted to the queues, it could allow an attacker to inject malicious or sensitive data into the queue, which could then be read by other authorized consumers. This could result in the exposure of sensitive information or the compromise of data integrity.
3. Denial of Service (DoS) attacks: Granting write access to the queues without proper security controls could also lead to DoS attacks. An attacker could flood the queue with a large number of messages, overwhelming the system and causing performance degradation or even complete unavailability of the queue service. This could disrupt the normal operation of applications relying on the queue service and impact overall system availability.

Remediation

​

Using Console

1. Enable Storage Analytics Logging:
   • Go to the Azure portal and navigate to the Azure Storage account.
   • Select the “Monitoring” section from the left-hand menu.
   • Click on “Storage Analytics” and then select “Logging”.
   • Enable logging by toggling the switch to “On”.
   • Configure the desired retention period for the logs.
   • Save the changes.
2. Enable Storage Analytics Metrics:
   • In the same “Monitoring” section of the Azure Storage account, click on “Storage Analytics” and then select “Metrics”.
   • Enable metrics by toggling the switch to “On”.
   • Configure the desired retention period for the metrics.
   • Save the changes.
3. Enable Soft Delete for Blob Storage:
   • Navigate to the Azure Storage account and select the “Blob service” from the left-hand menu.
   • Click on “Data protection” and then select “Soft delete”.
   • Enable soft delete by toggling the switch to “On”.
   • Configure the desired retention period for the deleted blobs.
   • Save the changes.

​

Using CLI

1. Enable soft delete for Azure Blob Storage:
   • Use the following command to enable soft delete for a specific storage account:
     Copy

     Ask AI

     az storage account blob-service-properties update --account-name <storage_account_name> --enable-delete-retention true --delete-retention-days <retention_days>
     

     Replace <storage_account_name> with the name of your storage account and <retention_days> with the number of days you want to retain deleted blobs.
2. Enable logging for Azure Storage:
   • Use the following command to enable logging for a specific storage account:
     Copy

     Ask AI

     az storage logging update --account-name <storage_account_name> --log <log_settings>
     

     Replace <storage_account_name> with the name of your storage account and <log_settings> with the desired logging settings.
3. Enable firewall rules for Azure Storage:
   • Use the following command to add a firewall rule for a specific storage account:
     Copy

     Ask AI

     az storage account network-rule add --account-name <storage_account_name> --ip-address <ip_address>
     

     Replace <storage_account_name> with the name of your storage account and <ip_address> with the IP address you want to allow access to the storage account.

​

Using Python

1. Monitor and handle storage exceptions:
   • Implement exception handling in your Python code to catch and handle any storage-related exceptions that may occur.
   • Use the try-except block to catch specific exceptions like azure.core.exceptions.ResourceNotFoundError or azure.core.exceptions.ServiceRequestError.
   • Handle the exceptions appropriately, such as logging the error, retrying the operation, or taking any necessary corrective actions.
2. Implement access control and security measures:
   • Ensure that appropriate access controls are in place for your Azure Storage resources.
   • Use Azure Active Directory (Azure AD) to authenticate and authorize access to your storage accounts.
   • Implement role-based access control (RBAC) to grant specific permissions to users or groups.
   • Regularly review and update access policies to ensure least privilege access.
3. Enable logging and monitoring:
   • Enable diagnostic logging for your Azure Storage accounts to capture relevant logs and metrics.
   • Use Azure Monitor to collect and analyze the logs and metrics.
   • Set up alerts and notifications to proactively detect and respond to any storage-related issues.
   • Leverage Azure Application Insights or other monitoring tools to gain insights into the performance and health of your storage resources.
