Microsoft.storage.storageaccounts.managementpolicies.delete remediation

​

Event Information

1. The Microsoft.Storage.storageAccounts.managementPolicies.delete event in Azure for Azure Storage indicates that a management policy for a storage account has been deleted.
2. This event signifies that any previously defined management policies, such as retention policies or tiering policies, will no longer be applied to the storage account.
3. It is important to monitor this event to ensure that the deletion of a management policy does not impact data retention or storage cost optimization strategies in the Azure Storage account.

​

Examples

1. Unauthorized deletion of management policies: If security is impacted with Microsoft.Storage.storageAccounts.managementPolicies.delete in Azure for AzureStorage, it could potentially allow unauthorized individuals to delete management policies associated with storage accounts. This could lead to the loss of important configuration settings and security controls, making the storage accounts more vulnerable to attacks.
2. Data exposure: If an attacker gains access to delete management policies for AzureStorage, they may be able to remove policies that enforce data encryption or access controls. This could result in sensitive data being exposed to unauthorized users, leading to potential data breaches and compliance violations.
3. Service disruption: Deleting management policies for AzureStorage can also impact the availability and reliability of the storage accounts. If critical policies related to data replication, backup, or disaster recovery are deleted, it could lead to service disruptions and potential data loss in case of failures or outages.

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 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.
