Control: 2.1.19 Ensure 'Additional email addresses' is Configured with a Security Contact Email

Description

Microsoft Defender for Cloud emails the subscription owners whenever a high-severity alert is triggered for their subscription. You should provide a security contact email address as an additional email address.

Microsoft Defender for Cloud emails the Subscription Owner to notify them about security alerts. Adding your Security Contact's email address to the 'Additional email addresses' field ensures that your organization's Security Team is included in these alerts. This ensures that the proper people are aware of any potential compromise in order to mitigate the risk in a timely fashion.

Remediation

From Azure Portal

  1. From Azure Home select the Portal Menu.
  2. Select Microsoft Defender for Cloud.
  3. Click on Environment Settings.
  4. Click on the appropriate Management Group, Subscription, or Workspace.
  5. Click on Email notifications.
  6. Enter a valid security contact email address (or multiple addresses separated by commas) in the Additional email addresses field.
  7. Click Save.

From Azure CLI

Use the below command to set Security contact emails to On.

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/se curityContacts/default?api-version=2020-01-01-preview -d@"input.json"'

Where input.json contains the data below, replacing validEmailAddress with a single email address or multiple comma-separated email addresses:

{
"id":"/subscriptions/<Your_Subscription_Id>/providers/Microsoft.Security/securityC ontacts/default",
"name": "default",
"type": "Microsoft.Security/securityContacts",
"properties": {
"email": "<validEmailAddress>",
"alertNotifications": "On",
"alertsToAdmins": "On"
}
}

Default Value

By default, there are no additional email addresses entered.
