Abstract
- NMEA 2000 is a widely used communication protocol in modern marine vessels but lacks essential security features such as encryption, authentication, and access control. This paper presents a practical guide for developing an Intrusion Detection System (IDS) tailored to NMEA 2000 networks. The system targets four common attack types: Denial of service (DoS), fuzzing, suspension, and masquerade attacks. Detection methods are based on message timing, pattern recognition, and payload analysis. Each method was implemented using Python and tested in a lab environment with real marine equipment. The IDS successfully identified simulated attacks in real time, demonstrating its effectiveness.
