A powerful, easily deployable network traffic analysis tool suite for network security monitoring
For a TL;DR
example of downloading, configuring, and running Malcolm in Docker on a Linux platform, see Installation example using Ubuntu 22.04 LTS.
For a more in-depth guide convering installing both Malcolm and a Hedgehog Linux sensor using the Malcolm installer ISO and Hedgehog Linux installer ISO, see End-to-end Malcolm and Hedgehog Linux ISO Installation.
The files required to build and run Malcolm are available on its GitHub page. Malcolm’s source-code is released under the terms of the Apache License, Version 2.0 (see LICENSE.txt
and NOTICE.txt
for the terms of its release).
The build.sh
script can build Malcolm’s images from scratch. See Building from source for more information.
The scripts to control Malcolm require Python 3. The install.py
script requires the dotenv, requests and ruamel.yaml modules for Python 3, and will make use of the pythondialog module for user interaction (on Linux) if it is available.
You must run auth_setup
prior to pulling Malcolm’s images. You should also ensure your system configuration and Malcolm settings are tuned by running ./scripts/install.py
and ./scripts/configure
(see Malcolm Configuration).
Users may wish to read the documentation on platform-specific host configuration:
Malcolm’s images are periodically built and hosted on GitHub. If you already have Docker and Docker Compose, these prebuilt images can be pulled by navigating into the Malcolm directory (containing the docker-compose.yml
file) and running docker compose --profile malcolm pull
like this:
$ docker compose --profile malcolm pull
Pulling api ... done
Pulling arkime ... done
Pulling dashboards ... done
Pulling dashboards-helper ... done
Pulling file-monitor ... done
Pulling filebeat ... done
Pulling freq ... done
Pulling htadmin ... done
Pulling logstash ... done
Pulling netbox ... done
Pulling netbox-postgresql ... done
Pulling netbox-redis ... done
Pulling nginx-proxy ... done
Pulling opensearch ... done
Pulling pcap-capture ... done
Pulling pcap-monitor ... done
Pulling suricata ... done
Pulling upload ... done
Pulling zeek ... done
You can then observe the images have been retrieved by running docker images
:
$ docker images

Once built, the malcolm_appliance_packager.sh
script can be used to create pre-packaged Malcolm tarballs for import on another machine. See Pre-Packaged Installation Files for more information.
Use the scripts in the scripts/
directory to start and stop Malcolm, view debug logs of a currently running
instance, wipe the database and restore Malcolm to a fresh state, etc.
A few minutes after starting Malcolm (probably 5 or so for Logstash to be completely loaded, depending on the system), the following services will be accessible:
sftp://<username>@127.0.0.1:8022/files
Malcolm can run on Podman as a rootless alternative to Docker. When Running Malcolm with Podman, podman compose
is used as a wrapper around an external compose provider (such as docker-compose
or podman-compose
), which in turn uses the Podman back end to run and orchestrate containers. The same Malcolm runtime scripts (e.g., ./scripts/start
, ./scripts/stop
, etc.) are used whether using Docker or Podman.
As it is a somewhat more advanced procedure, installation and configuration of Podman is not covered in this documentation. Please see the Podman documentation.
It should be noted that if rootless Podman is used, Malcolm itself cannot perform traffic capture on local network interfaces, although it can accept network traffic metadata forwarded from a a network sensor appliance.
