The CAN bus protocol is used in modern vehicles to control dozens of devices. It is simple enough, but this protocol lacks security mechanisms, and that is one of the main reasons that the entire vehicle is vulnerable for different cyber-physical attacks. Therefore, the detection and counteraction against such attacks on the CAN bus protocol is an important task. In the paper, we present an approach for visual analysis of the CAN bus protocol traffic dumps, which is based on visualization of traffic timeline segments by using radial bar charts. Experiments for visualization of traffic dumps are presented. The advantages of the proposed approach are simplicity and clarity in determining attacks. The proposed model allows displaying a large amount of detailed information for a long-time period at one time and on one screen.
