01 Define the configuration parameters for the account get-access-token command in order to enable high severity alert notifications for Microsoft Defender for Cloud by setting the "alertNotifications" parameter to "On". Save the configuration document to a JSON file named enable-high-severity-alerts.json and replace the highlighted details, i.e. <azure-subscription-id> and <valid-email-address> (optional, see this conformity rule), with your own Azure account subscription details:

{
"id": "/subscriptions/<azure-subscription-id>/providers/Microsoft.Security/securityContacts/default",
  "name": "default",
  "type": "Microsoft.Security/securityContacts",
  "properties": {
  "email": "<valid-email-address>",
    "alertNotifications": "On",
    "alertsToAdmins": "On"
  }
}

02 Run account get-access-token command (Windows/macOS/Linux) using the configuration document defined at the previous step (i.e. enable-high-severity-alerts.json file), to enable high severity alert email notifications for Microsoft Defender for Cloud in selected Azure 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.Security/securityContacts/default1?api-version=2017-08-01-preview -d@"enable-high-severity-alerts.json"'

03 The output should return the account get-access-token command request metadata:

{
"id": "/subscriptions/<azure-subscription-id>/providers/Microsoft.Security/securityContacts/default",
  "name": "default",
  "type": "Microsoft.Security/securityContacts",
  "properties": {
  "email": "<valid-email-address>",
    "alertNotifications": "On",
    "alertsToAdmins": "On"
  }
}

04 Repeat steps no. 1 – 3 for each Microsoft Azure subscription available in your Azure cloud account.
