Defender for Identity notifications in Microsoft Defender XDR

  • Article

Microsoft Defender for Identity provides notifications for health issues and security alerts, either via email notifications or to a Syslog server.

This article describes how to configure Defender for Identity notifications so that you're aware of any health issues or security alerts detected.

Tip

In addition to email or Syslog notifications, we recommend that SOC admins use Microsoft Sentinel to view all alerts in a single portal. For more information, see Microsoft Defender XDR integration with Microsoft Sentinel. To integrate other SIEM tools, see Integrate your SIEM tools with Microsoft Defender XDR.

Configure email notifications

This section describes how to configure email notifications for Defender for Identity health issues or security alerts.

  1. In Microsoft Defender XDR, select Settings > Identities.

  2. Under Notifications, select Health issues notifications or Alert notifications as needed.

  3. In the Add recipient email, enter the email address(es) where you want to receive email notifications, and select + Add.

Whenever Defender for Identity detects a health issue or security alert, configured recipients receive an email notification with the details, with a link to Microsoft Defender XDR for more details.

Note

Alert notifications page will be deprecated by January 15, 2025. Please use the 'Email Notifications' page under Defender XDR settings for new and existing notifications rules. Learn more

Configure Syslog notifications

This section describes how to configure Defender for Identity to send health issues and security events to a Syslog server through a configured sensor.

Events aren't sent from the Defender for Identity service to your Syslog server directly, but only through the sensor.

To configure Syslog notifications:

  1. In Microsoft Defender XDR, select Settings > Identities.

  2. Under Notifications, select Syslog notifications and then toggle on the Syslog service option.

  3. Select Configure service to open the Syslog service pane.

  4. Enter the following details:

    • Sensor: Select the sensor you want to send notifications to the Syslog server
    • Service endpoint and Port: Enter the IP address or fully qualified domain name (FQDN) for the Syslog server, and then enter the port number. You can configure only one Syslog endpoint.
    • Transport: Select the Transport protocol (TCP or UDP).
    • Format: Select the format (RFC 3164 or RFC 5424).

  5. Select Send test SIEM notification and then verify the message is received in your Syslog infrastructure solution.

  6. When you've confirmed that the test works, select Save.

  7. After configuring the Syslog service, select the types of notifications to send to your Syslog server, including whenever:

    • A new security alert is detected
    • An existing security alert is updated
    • A new health issue is detected

Tip

When working with Syslog in TLS mode, make sure to install the required certificates on the designated sensor.

Creating automation scripts for Defender for Identity SIEM logs

If you're creating automation scripts for Defender for Identity SIEM logs, we recommend using the externalId field to identify the alert type instead of using the alert name.

While alert names may occasionally be modified, the externalId of each alert is permanent. For more information, see Defender for Identity SIEM log reference.
