     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 control measures are in place for your Azure Storage resources.
   • Use the Azure Identity library in Python to authenticate and authorize access to your storage accounts.
   • Follow the principle of least privilege and grant only the necessary permissions to users or applications accessing the storage resources.
   • Regularly review and update access control policies to align with your security requirements.
3. Enable logging and monitoring:
   • Enable logging for your Azure Storage accounts to capture relevant events and activities.
   • Use Azure Monitor to collect and analyze logs, metrics, and other telemetry data from your storage accounts.
   • Implement proactive monitoring and alerting mechanisms to detect any anomalies or suspicious activities.
   • Leverage Azure Monitor’s integration with Azure Functions or Logic Apps to trigger automated responses or remediation actions based on specific events or conditions.
