ANALYSIS OF SECURITY VULNERABILITIES IN VEHICLE ON-BOARD DIAGNOSTIC SYSTEMS

The article explains the different types of on-board diagnostic systems (OBD) used in motor vehicles, as well as the impact of the latest automotive security norms on diagnostic interface security. The paper focuses on identifying potential security threats in on-board diagnostic systems used in automotive control units. During the research, a diagnostic interface device of its own design, carrying out special test procedures, was excavated. The research was conducted on several vehicles and ECUs, applying black box penetration testing. The paper's goal is to list all identified vulnerabilities in diagnostic protocol implementation and suggest some corrective actions for software that would increase security. The authors defined a list of low-cost software requirements that can be easily implemented on most modern ECUs.
