1. The Microsoft.Storage.storageAccounts.managementPolicies.write event in Azure for Azure Storage refers to a write operation performed on the management policies of a storage account.
2. This event indicates that a change or update has been made to the management policies of an Azure Storage account.
3. It is important to monitor this event as it can help track any modifications made to the management policies, such as changes in retention periods, tiering settings, or blob lifecycle rules, ensuring compliance and maintaining data governance.

​

Examples

1. Unauthorized modification of management policies: If security is impacted with Microsoft.Storage.storageAccounts.managementPolicies.write in Azure for AzureStorage, it could potentially allow unauthorized users to modify the management policies of storage accounts. This could lead to unauthorized access, data leakage, or data loss if the policies are modified in a way that compromises the security controls in place.
2. Exposure of sensitive data: If security is impacted with Microsoft.Storage.storageAccounts.managementPolicies.write in Azure for AzureStorage, it could allow attackers to modify the management policies to enable public access to the storage account or its contents. This could result in the exposure of sensitive data to unauthorized users, violating data privacy and compliance regulations.
3. Disruption of storage operations: If security is impacted with Microsoft.Storage.storageAccounts.managementPolicies.write in Azure for AzureStorage, attackers could potentially modify the management policies in a way that disrupts storage operations. For example, they could delete or modify critical data, disrupt backups or replication processes, or introduce malicious code into the storage account. This could lead to service disruptions, data corruption, or loss of data 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 soft 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 from.

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 control policies to adhere to the principle of least privilege.
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 based on specific conditions or thresholds to proactively identify and address any issues.
   • Leverage Azure Application Insights or other monitoring tools to gain insights into the performance and behavior of your storage resources.
