Overview

The general and most generic way of receiving logs from Control D's SIEM output integration is by deploying our pre-built docker container.

This container securely terminates log data sent from our network to yours, and forwards it on to a SIEM tool within your network.

Pre-Requisites

Customer Side

• Hardware
  • Virtual Machine, VPS, or Baremetal Server (X86 architecture)
• Operating System
  • Linux Distribution (capable of running Docker Containers / Docker CE)
• Networking
  • Public Static IP address (For securely receiving logs from our SIEM integration output over the internet)
  • Internal network access to your SIEM system (For forwarding logs received into your system)
• Firewall / Container Port Mappings
  • Permit inbound traffic on tcp/24224 to the docker container

Submitting Details to Support

Our system will generate a docker config bundle file for you. Just send an e-mail to Control D Support asking for the SIEM Integration config bundle with your:

• Org ID
• Public IP address
• [Optional] DNS record (if the public IP is prone to changing / dynamic)

Installation

1. Install Docker Engine on the host. Instructions Link

2. Upload the config bundle to the host

   Shell

   scp yourbundle.tar.gz your-linux-host.example.com:/tmp/	
   

3. Extract the config + container bundle:

   Shell

   mkdir logs-receiver
   tar -xvf /tmp/yourbundle.tar.gz -C logs-receiver
   

4. Start the container (interactively at first for testing)

   Shell

   cd logs-receiver
   docker compose up
   

5. Confirm that logs are arriving (they won't be going anywhere yet!)

6. Modify the configuration logs-receiver/fluent-bit.yaml and update the outputs: section to add your desired logs destination.

   See https://docs.fluentbit.io/manual/pipeline/outputs for instructions

   fluent-bit supports a wide variety of log collectors, including ELK, Datadog and Splunk

   Example: Splunk

   Example: Splunk

   outputs:
     - name: splunk
       host: splunk.example.com                           # Modify 
       splunk_token: 55555555-5555-5555-5555-555555555555 # Modify
       port: 8088                                         # Modify
       tls: on                                            # Modify
       tls.verify: on                                     # Modify
   

7. Start the container in daemon mode so it continues running when you close your shell:

   Bash

   docker compose up --detach
   

8. Please notify the Control D support team to confirm that you are receiving logs successfully!

Troubleshooting

• If your destination system does not receive logs, check the running fluent-bit instance for errors:

  docker compose logs --follow
  

• If needed, restart the container with:
  Bash

  docker compose up --force-recreate --detach
  

Example Config

Here is a sample docker compose file and fluent-bit config that you can use to start a fluentbit receiver on your end. Be mindful this not a working sample. It lists templated components that you will need to comment out or provide.

More importantly it will not actually receive anything from Control D until we create a custom configuration. Once you're ready to proceed, provide us with the org IDs you wish to receive status for and we'll send you a final config bundles.
