Abstract

As technology advances, it is possible to process a lot of data, and as various elements in the city become diverse and complex, cities are becoming smart cities. One of the core systems of smart cities is Cooperative-Intelligent Transport Systems (C-ITS). C-ITS is a system that provides drivers with real-time accident risk information such as surrounding traffic conditions, sudden stops, and falling objects while a vehicle is driving, and consists of road infrastructure, C-ITS center, and vehicle terminals. Meanwhile, smart cities can have cybersecurity problems because many elements of the city are networked and electronically controlled. If cybersecurity problems occur in C-ITS, there is a high risk of safety problems. The purpose of this technical document is to describe C-ITS environment modeling and C-ITS attack scenarios for C-ITS security. After describing the concept of C-ITS and MITRE ATT&CK, we describe the C-ITS environment model and the attack scenario model that we define.
