Examples

1. Unauthorized Write Access: If security is impacted with Microsoft.Storage.storageAccounts.tableServices.write in Azure for AzureStorage, it could mean that unauthorized users or entities have gained write access to the storage account’s table services. This can lead to potential data breaches or unauthorized modifications to the data stored in the tables.
2. Data Integrity Issues: Another impact of security being compromised with Microsoft.Storage.storageAccounts.tableServices.write is the potential for data integrity issues. Unauthorized write access can result in the insertion, modification, or deletion of data in the tables, leading to inconsistencies or corruption of the stored data.
3. Compliance Violations: Security impacts with Microsoft.Storage.storageAccounts.tableServices.write can also result in compliance violations. If unauthorized write access is gained, it may lead to the unauthorized modification or deletion of sensitive data, which can violate data protection regulations or industry-specific compliance standards. This can have legal and reputational consequences for the organization.

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 be collected.
   • 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 notifying the appropriate stakeholders.
2. Implement access control and security measures:
   • Ensure that appropriate access control measures 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. Optimize storage performance and cost:
   • Use Python SDKs like azure-storage-blob or azure-storage-file-share to interact with Azure Storage resources.
   • Leverage features like parallelism and asynchronous operations to improve performance.
   • Implement data compression and deduplication techniques to reduce storage costs.
   • Regularly monitor and analyze storage usage to identify opportunities for optimization.
