### Classify an alert
|
||||
|
||||
Your security team can classify an alert as a false positive or a true positive in the Microsoft Defender Security Center, in the **Alerts queue**.
|
||||
|
||||
1. Go to the Microsoft Defender Security Center ([https://securitycenter.windows.com](https://securitycenter.windows.com)) and sign in.
|
||||
2. Select **Alerts queue**, and then select an alert that is a false positive.
|
||||
3. For the selected alert, select **Actions** > **Manage alert**. A flyout pane opens.
|
||||
4. In the **Manage alert** section, select **True alert** or **False alert**. Use **False alert** to classify a false positive.
|
||||
4. In the **Manage alert** section, select either **True alert** or **False alert**. (Use **False alert** to classify a false positive.)
|
||||
|
||||
> [!TIP]
|
||||
> For more information about suppressing alerts, see [Manage Microsoft Defender for Endpoint alerts](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/manage-alerts). And, if your organization is using a security information and event management (SIEM) server, make sure to define a suppression rule there, too.
