CAN We Trust Your Results? A Cross-Dataset Study of Automotive IDS Evaluation

arXiv:2606.30430v1 Announce Type: cross Abstract: The increasing connectivity of modern vehicles has made securing in-vehicle communication networks a critical challenge. Intrusion Detection Systems (IDS) have been widely studied as a defense mechanism for detecting malicious activities on the Controller Area Network (CAN) bus. However, the evaluation of CAN IDS methods remains difficult due to inconsistencies in experimental setups and the lack of standardized benchmarking frameworks. As a result, reported performance often depends on dataset-specific characteristics and may not reflect how d

Why this matters
Why now

The increasing connectivity of modern vehicles is creating new attack surfaces, making robust cybersecurity solutions for automotive networks an immediate priority.

Why it’s important

This paper highlights critical weaknesses in the evaluation of automotive IDS, which is fundamental for ensuring vehicle safety and cybersecurity as autonomous and connected vehicles become more prevalent.

What changes

The current, inconsistent evaluation of automotive IDS requires a more standardized and rigorous approach, impacting future development and deployment strategies for in-vehicle security.
