List of changes in Malcolm v3.2.0:

v3.1.0...v3.2.0

  • New features

    • "Best Guess" Fingerprinting for ICS Protocols - In an effort to help identify more ICS traffic, Malcolm can use "buest guess" method based on transport protocol (e.g., TCP or UDP) and port(s) to categorize potential traffic communicating over some ICS protocols without full parser support. This feature involves a mapping table and a Zeek script to look up the transport protocol and destination and/or source port to make a best guess at whether a connection belongs to one of those protocols. These potential ICS communications are categorized by vendor where possible. The list of ICS protocols' ports was adapted from various public sources, including, but not limited to, Grassmarlin's fingerprints and ITI/ICS-Security-Tools' list of Control Systems Ports.
