Threat Analysis of Wi-Fi Connected Dashboard Camera

Recently dashboard camera (dashcam) has a function of connecting Wi-Fi to a smartphone for usability. But, it has severe vulnerabilities that it doesn't have authentication process. We analyzed threats of overall functions of dashcam using Data Flow Diagram and STRIDE analysis. After that, we found that dashcam’ s vulnerabilities are closely related to Wi-Fi function and lack of authentication process. We made sets of possible attacks and presented as attack trees. Attack Tree Analysis was used to categorize and prioritize among several ways of possible attacks. This research contributes to suggest vulnerabilities of a dashcam. This emphasizes the importance that information security standards of dashcam should be made and manufacturers of dashcam should apply the standards.
