Malcolm is a powerful, easily deployable network 🖧 traffic analysis tool suite for network security monitoring 🕵🏻♀️.
Malcolm operates as a cluster of containers 📦, isolated sandboxes which each serve a dedicated function of the system. This makes Malcolm deployable with frameworks like Docker 🐋, Podman 🦭, and Kubernetes ⎈. Check out the Quick Start guide for examples on how to get up and running.
Alternatively, dedicated official ISO installer images 💿 for Malcolm and Hedgehog Linux 🦔 can be downloaded from Malcolm's releases page on GitHub. Due to limits on individual files in GitHub releases, these ISO files have been split 🪓 into 2GB chunks and can be reassembled with scripts provided for both Bash 🐧 (release_cleaver.sh) and PowerShell 🪟 (release_cleaver.ps1). See Downloading Malcolm - Installer ISOs for instructions.
