Enable Storage Encryption Monitoring

01 Sign in to Azure Management Console.

02 Navigate to Azure Security Center blade at https://portal.azure.com/#blade/Microsoft_Azure_Security/SecurityMenuBlade/.

03 In the navigation panel, choose Security policy to access Policy Management portal.

04 On the Policy Management page, click on the name of the subscription that you want to examine to access the selected subscription configuration settings.

05 On the Security Policy page, click on the ASC Default (subscription: <azure-subscription-id>) policy assignment to access the policy configuration.

06 On the selected policy assignment page, in the PARAMETERS section, check the Monitor storage blob encryption configuration setting. If the setting is set to Disabled, the storage encryption monitoring is not enabled for the Microsoft Azure Storage blob resources available in the current subscription.

07 Repeat steps no. 4 - 6 for each Microsoft Azure subscription available in your account.

01 Run account get-access-token command (Windows/macOS/Linux) using custom query filters to retrieve the "Monitor Storage Blob Encryption" feature status for the current Azure account subscription:

az account get-access-token
	--query "{subscription:subscription,accessToken:accessToken}"
	--out tsv | xargs -L1 bash -c 'curl -X GET -H "Authorization: Bearer $1" -H "Content-Type: application/json" https://management.azure.com/subscriptions/$0/providers/Microsoft.Authorization/policyAssignments/SecurityCenterBuiltIn?api-version=2018-05-01' | jq 'select(.name=="SecurityCenterBuiltIn")'|jq '.properties.parameters.storageEncryptionMonitoringEffect.value'

02 The command output should return the storage encryption monitoring configuration status:

"Disabled"

03 Repeat step no. 1 and 2 for each Microsoft Azure subscription available in your account.

01 Sign in to Azure Management Console.

02 Navigate to Azure Security Center blade at https://portal.azure.com/#blade/Microsoft_Azure_Security/SecurityMenuBlade/.

03 In the navigation panel, choose Security policy to access Policy Management portal.

04 On the Policy Management page, click on the name of the subscription that you want to examine to access the selected subscription configuration settings.

05 On the Security Policy page, click on the ASC Default (subscription: <azure-subscription-id>) policy assignment to edit the policy configuration.

06 On the selected policy assignment page, in the PARAMETERS section, select Audit from Monitor storage blob encryption dropdown list to enable the monitoring of blob encryption for the storage account in the selected Azure subscription.

07 Click Save to apply the changes. If successful, the following message should be displayed: "Updating policy assignment succeeded". Once the configuration changes are saved, the "Monitor Storage Blob Encryption" feature becomes active for the selected Azure subscription.

08 If required, repeat steps no. 4 – 7 for other Microsoft Azure cloud subscription available.

01 Define the necessary parameters for the account get-access-token command, where the storageEncryptionMonitoringEffect configuration parameter is enabled. Save the following content to a JSON file named enable-storage-encryption-monitoring.json and replace the highlighted details, i.e. <azure-subscription-id> and <policy-definition-id>, with your own Azure account details:

{
   "properties":{
      "displayName":"ASC Default (subscription: <azure-subscription-id>)",
      "policyDefinitionId":"/providers/Microsoft.Authorization/policySetDefinitions/<policy-definition-id>",
      "scope":"/subscriptions/<azure-subscription-id>",
      "parameters":{
         "storageEncryptionMonitoringEffect":{
            "value":"Audit"
         }
      }
   },
   "id":"/subscriptions/<azure-subscription-id>/providers/Microsoft.Authorization/policyAssignments/SecurityCenterBuiltIn",
   "type":"Microsoft.Authorization/policyAssignments",
   "name":"SecurityCenterBuiltIn",
   "location":"eastus"
}

02 Run account get-access-token command (Windows/macOS/Linux) using the parameters defined at the previous step (i.e. enable-storage-encryption-monitoring.json file) to enable storage encryption monitoring and recommendations for the selected Microsoft Azure cloud subscription:

az account get-access-token
	--query "{subscription:subscription,accessToken:accessToken}"
	--out tsv | xargs -L1 bash -c 'curl -X PUT -H "Authorization: Bearer $1" -H "Content-Type: application/json" https://management.azure.com/subscriptions/$0/providers/Microsoft.Authorization/policyAssignments/SecurityCenterBuiltIn?api-version=2018-05-01 -d@"enable-storage-encryption-monitoring.json"'

03 If successful, the command output should return the updated Azure Security Center policy:

{
   "sku":{
  	"name":"A0",
  	"tier":"Free"
   },
   "properties":{
  	"displayName":"ASC Default (subscription: abcdabcd-1234-1234-1234-abcdabcdabcd)",
  	"parameters":{
     	"storageEncryptionMonitoringEffect":{
        	"value":"Audit"
     	}
  	},

  	...

   },
   "id":"/subscriptions/abcdabcd-1234-1234-1234-abcdabcdabcd/providers/Microsoft.Authorization/policyAssignments/SecurityCenterBuiltIn",
   "type":"Microsoft.Authorization/policyAssignments",
   "name":"SecurityCenterBuiltIn",
   "location":"eastus"
}

04 If required, repeat steps no. 1 – 3 for other Microsoft Azure cloud subscription available.
