Configure Azure ATP sensor settings

In this article, you'll learn how to correctly configure Azure ATP sensor settings to start seeing data. You'll need to do additional configuration and integration to take advantage of Azure ATP's full capabilities.

Prerequisites

Configure sensor settings

After the Azure ATP sensor is installed, do the following to configure Azure ATP sensor settings.

  1. Click Launch to open your browser and sign in to the Azure ATP portal.

  2. In the Azure ATP portal, go to Configuration and, under the System section, select Sensors.

  3. Click on the sensor you want to configure and enter the following information:

    • Description: Enter a description for the Azure ATP sensor (optional).

    • Domain Controllers (FQDN) (required for the Azure ATP standalone sensor, this can't be changed for the Azure ATP sensor): Enter the complete FQDN of your domain controller and click the plus sign to add it to the list. For example, dc01.contoso.com

      The following information applies to the servers you enter in the Domain Controllers list:

      • All domain controllers whose traffic is being monitored via port mirroring by the Azure ATP standalone sensor must be listed in the Domain Controllers list. If a domain controller isn't listed in the Domain Controllers list, detection of suspicious activities might not function as expected.
      • At least one domain controller in the list should be a global catalog. This enables Azure ATP to resolve computer and user objects in other domains in the forest.
    • Capture Network adapters (required):

    • For Azure ATP sensors, all network adapters that are used for communication with other computers in your organization.

    • For Azure ATP standalone sensor on a dedicated server, select the network adapters that are configured as the destination mirror port. These network adapters receive the mirrored domain controller traffic.

  4. Click Save.

Validate installations

To validate that the Azure ATP sensor has been successfully deployed, check the following:

  1. Check that the service named Azure Advanced Threat Protection sensor is running. After you save the Azure ATP sensor settings, it might take a few seconds for the service to start.

  2. If the service doesn't start, review the “Microsoft.Tri.sensor-Errors.log” file located in the following default folder, “%programfiles%\Azure Advanced Threat Protection sensor\Version X\Logs”.

    Note

    The version of Azure ATP updates frequently, to check the latest version, in the Azure ATP portal, go to Configuration and then About.

  3. Go to your Azure ATP instance URL. In the Azure ATP portal, search for something in the search bar, such as a user or group on your domain.

  4. Verify ATP connectivity on any domain device using the following steps:

    1. Open a command prompt
    2. Type nslookup
    3. Type server then the FQDN or IP address of the domain controller where the ATP sensor is installed. For example, server contosodc.contoso.azure
      • Make sure to replace contosodc.contoso.azure and contoso.azure with the FQDN of your Azure ATP sensor and domain name respectively.
    4. Type ls -d contoso.azure
    5. Repeat steps 3 and 4 for each sensor you wish to test.
    6. From the Azure ATP console, open the entity profile for the computer you ran the connectivity test from.
    7. Check the related logical activity and confirm connectivity.

    Note

    If the domain controller you wish to test is your first deployed sensor, wait at least 15 minutes to allow the database backend to finish initial deployment of the necessary microservices before you attempt to verify the related logical activity for that domain controller.
