Microsoft.storage.storageaccounts.write remediation

​

Event Information

1. The Microsoft.Storage.storageAccounts.write event in Azure for Azure Storage refers to an operation that writes data to a storage account in Azure.
2. This event is triggered when there is a request to create, update, or delete a storage account, or when data is being written to a storage account.
3. It is important to monitor this event as it provides insights into the activity and usage of Azure Storage, allowing you to track changes, troubleshoot issues, and ensure compliance with data governance policies.

​

Examples

1. Unauthorized access: If security is impacted with Microsoft.Storage.storageAccounts.write in Azure for AzureStorage, it could potentially lead to unauthorized access to the storage accounts. This means that an attacker could gain access to sensitive data stored in the storage accounts, compromising the confidentiality and integrity of the data.
2. Data leakage: Another impact of security being compromised with Microsoft.Storage.storageAccounts.write is the risk of data leakage. If an unauthorized user gains write access to the storage accounts, they could potentially modify or delete data, leading to data loss or unauthorized disclosure of sensitive information.
3. Malware injection: Security impact with Microsoft.Storage.storageAccounts.write can also result in the injection of malware into the storage accounts. An attacker could upload malicious files or scripts into the storage accounts, which can then be executed, potentially leading to further compromise of the environment or other connected systems.

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”.
   • Choose the desired metrics to collect.
   • 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 retry logic:
   • Azure Storage operations can sometimes fail due to transient errors. Implementing retry logic can help mitigate these issues.
   • Use the azure.core.retry module to define a retry policy for your storage operations.
   • Configure the retry policy with parameters like maximum number of retries, backoff interval, and retryable error codes.
   • Wrap your storage operations in a retry loop to automatically retry the operation if it fails.
3. Optimize storage performance:
   • To improve the performance of your Azure Storage operations, consider implementing the following optimizations:
   • Use batch operations: Instead of making individual requests for each operation, use batch operations to perform multiple operations in a single request.
   • Leverage parallelism: If you have a large number of storage operations to perform, consider using parallel processing techniques to distribute the workload across multiple threads or processes.
   • Implement caching: If you frequently access the same data from Azure Storage, consider implementing a caching mechanism to reduce the number of requests and improve response times.
