Ensure that additional email addresses are configured for the subscription's security contact settings in Microsoft Defender for Cloud, so that security alerts are sent to multiple designated recipients beyond just the subscription owner.
Configuring additional email addresses for security alerts ensures that multiple stakeholders receive notifications about security events. Relying solely on the subscription owner for alert notifications creates a single point of failure. If the owner is unavailable, critical alerts may be missed. By adding additional security contacts, organizations ensure broader coverage and faster incident response times.
Adding additional email addresses has minimal technical impact. Recipients will receive security alert emails, which may increase email volume depending on the environment. Organizations should ensure all listed contacts are relevant security personnel who can act on the alerts.
From Azure Portal:
Microsoft Defender for Cloud.Management, click Environment settings.Email notifications blade.Additional email addresses field contains one or more valid email addresses (separated by semicolons).From Azure CLI:
az rest --method get --url "https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.Security/securityContacts?api-version=2020-01-01-preview"
Verify that the emails property contains additional email addresses beyond the subscription owner.
