Darktrace DETECT

Log collector Network

You must have the Network integrations license pack to use this feature.

You can integrate Darktrace DETECT with Sophos Central so that it sends alerts to Sophos.

This integration uses a log collector hosted on a virtual machine (VM). Together they're called an integration appliance. The appliance receives third-party data and sends it to the Sophos Data Lake.

This page describes integration using an appliance on ESXi or Hyper-V. If you want to integrate using an appliance on AWS, see Integrations on AWS.

Key steps

The key steps in an integration are as follows:

  • Add an integration for this product. In this step, you create an image of the appliance.
  • Download and deploy the image on your VM. This becomes your appliance.
  • Configure Darktrace DETECT to send data to the appliance.

Requirements

Appliances have system and network access requirements. To check that you meet them, see Appliance requirements.

Add an integration

To add the integration, do as follows:

  1. In Sophos Central, go to Threat Analysis Center > Integrations > Marketplace.

  2. Click Darktrace. Make sure you click the card for Darktrace DETECT, not Darktrace Email.

    The Darktrace page opens. You can add integrations here and see a list of any you've already added.

  3. In Data Ingest (Security Alerts), click Add Configuration.

    Note

    If this is the first integration you've added, we'll ask for details about your internal domains and IPs. See Provide your domain and IP details.

    Integration setup steps appears.

Configure the appliance

In Integration setup steps, you can configure a new appliance or use an existing one.

We assume here that you configure a new appliance. To do this, create an image as follows:

  1. Enter an integration name and description.
  2. Click Create new appliance.
  3. Enter a name and description for the appliance.
  4. Select the virtual platform. Currently we support VMware ESXi 6.7 Update 3 or later and Microsoft Hyper-V 6.0.6001.18016 (Windows Server 2016) or later.

  5. Specify the IP settings for the Internet-facing network ports. This sets up the management interface for the appliance.

    • Select DHCP to assign the IP address automatically.

      Note

      If you select DHCP, you must reserve the IP address.

    • Select Manual to specify network settings.

  6. Select the Syslog IP version and enter the Syslog IP address.

    You'll need this syslog IP address later, when you configure Darktrace DETECT to send data to your appliance.

  7. In Protocol, TCP is pre-selected. You can't change it.

    When you configure Darktrace DETECT to send data to your appliance, you must make sure it uses the same protocol.

  8. Click Save.

    We create the integration and it appears in your list.

    In the integration details, you can see the port number for the appliance. You'll need this later when you configure Darktrace DETECT to send data to it.

    It might take a few minutes for the appliance image to be ready.

Deploy the appliance

Restriction

If you're using ESXi, the OVA file is verified with Sophos Central, so it can only be used once. If you have to deploy another VM, you must create an OVA file again in Sophos Central.

Use the image to deploy the appliance as follows:

  1. In the list of integrations, in Actions, click the download action for your platform, for example Download OVA for ESXi.
  2. When the image download finishes, deploy it on your VM. See Deploy appliances.

Configure Darktrace DETECT

You now configure Darktrace DETECT to send alerts to us, using syslog forwarding.

Note

You can configure multiple instances of Darktrace DETECT to send data to Sophos via the same appliance. After you finish integration, repeat the steps in this section for your other instances of Darktrace DETECT. You don't need to repeat the steps in Sophos Central.

To configure alert forwarding, do as follows:

  1. Sign in to Darktrace DETECT.
  2. In the Threat Visualizer, go to Admin.
  3. Under System Configuration, click Modules.
  4. On the Modules page, click Workflow Integrations.
  5. Find Syslog and click it.
  6. On the Syslog page, select the Syslog CEF tab.

  7. Click New.

    The Syslog configuration settings are shown. We recommend that you do all the configuration before you turn on Send Alerts.

  8. In Server, enter the IP address of your appliance.

  9. In Server Port, enter the Port on which your appliance listens.

    You must enter the same settings for IP address and port that you entered in Sophos Central when you added the integration.

  10. Turn on Show Advanced Options.

    In the first section, turn on Send Alerts Using TCP.

  11. Turn on Send AI Analyst Alerts.

  12. Set Minimum AI Analyst Incident Event Score and Minimum AI Analyst Incident Score to 0. This maximizes the alerts sent to Sophos.
  13. Click Add.
  14. Go back to the top of the page and click Verify alert sending. This sends a test alert to your appliance.
  15. Turn on Send Alerts and save your changes.

Darktrace DETECT alerts appear in the Sophos Data Lake after validation.
