Hands-On Exploration of J1939 and NMEA 2000 Networks and Their Security Flaws

This tutorial provides a hands-on introduction to SAE J1939 and NMEA 2000 communication standards, foundational to networking in commercial vehicles and marine platforms. Participants will explore protocol architecture, including frame formats, addressing, arbitration, and multi-packet transport, through guided decoding exercises using real network traces. The session then shifts to protocol-level vulnerabilities rooted in design flaws—such as spoofing, denial-of-service, and control flow disruption—with live demonstrations on a virtual platform. Attendees will gain practical experience using open-source tools to assess vulnerabilities and inform safer protocol implementation.
