Fortinet FortiAnalyzer (Log collector)

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

Note

This integration lets the FortiAnalyzer Appliance and VM Subscription products forward data to Sophos. However, FortiAnalyzer Cloud can't forward logs, including security events, so isn't compatible with this integration. See Limitations of FortiAnalyzer Cloud.

Note

An API-based integration of FortiAnalyzer is also available. See Integrate Fortinet FortiAnalyzer (API).

You can integrate Fortinet FortiAnalyzer with Sophos Central so that it sends firewall alerts to Sophos for analysis.

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.

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 FortiAnalyzer 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 Fortinet FortiAnalyzer (Log collector).

    The Fortinet FortiAnalyzer (Log collector) 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 your 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 FortiAnalyzer to send data to your appliance.

  7. Select a Protocol.

    You must use the same protocol later when you configure FortiAnalyzer to send data to your appliance.

  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 FortiAnalyzer 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 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, under 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 FortiAnalyzer

Now you configure FortiAnalyzer to send alerts to the Sophos appliance on the VM.

Note

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

You can configure log forwarding in the FortiAnalyzer console as follows:

  1. Go to System Settings > Log Forwarding.
  2. Click Create New.
  3. On the Create New Log Forwarding page, enter the following details:

    1. Name: Enter a name for the server, for example "Sophos appliance".
    2. Status: Set this to On.
    3. Remote Server Type: Select Common Event Format (CEF).
    4. Server IP: Enter the IP address of your appliance. This is the syslog IP address you entered in Sophos Central.
    5. Server Port: Enter the port number you set in Sophos Central.
    6. Reliable Connection: Turn this on to use a TCP connection. Turn it off to use a UDP connection. This must match the protocol that you set earlier in Sophos Central.
    7. Sending Frequency. Skip this option. It is only for FortiAnalyzer servers.
    8. Log Forwarding Filters: We recommend that you don't apply filters to FortiAnalyzer. Sophos applies filtering at the appliance.
    9. Click OK.

The FortiAnalyzer device will start forwarding logs to the appliance.
