Improve cybersecurity of CITS Road Side Infrastructure Installations: the SerIoT  Secure and Safe IoT approach Cooperative Intelligent Transport Systems (CITS) need to be secured as it is deployed on roads in Europe. While some aspects of the communication security are secured others could still need improvement. SerIoT as a security project for the internet of things and offers various security mechanisms from the IoT domain which could be beneficial for CITS. Such security mechanisms contain a software defined network, the usage of honeypots and several mechanisms to analyze, monitor and mitigate threats on the system. Therefore CITS will benefit tremendously of the functionalities from these security mechanisms designed to cope with large attack surfaces and high network traffic found in IoT environments. To enable these technologies, modules developed within SerIoT are planned to be integrated into the Road Side ITS station. The station will also be connected to SerIoT SDN routers providing security for the station from malicious vehicles and the network

Preliminary Considerations for a Cooperative Intelligent Transport System Cybersecurity Reference Architecture Cyber security and privacy are major challenges for interconnected automatic driving cars which rely on confidentiality, integrity, availability, authenticity, accountability as well as privacy of a cooperative intelligent transport system (CITS). The cars require detailed data about the environment on different levels to generate a comprehensive overview of the current traffic situation in real time to ensure their safe and secure movement. The availability, integrity, authenticity and accountability of data and its processing are a prerequisite for automated and interconnected driving. Additionally, confidentiality and privacy are main requirements for using CITS services. Cyber security is not only necessary for an efficient traffic management. Cooperative functions and coordinative autonomy is mandatory, since successful intentional attacks on a CITS in fact threaten human lives. There is a fundamental need for a comprehensive harmonization of safety and security aspects from the infrastructure provideru0027s perspective to ensure awareness and trust  and not solely from an original equipment manufactureru0027s (OEM) view. Especially cyber security is essential to make these cooperative traffic structures and autonomous interconnected driving technologies confidently available to society. In this paper, the approach for component identification, scoping, use case development, and the applied risk management method as preliminary work for the development of a comprehensive CITS cybersecurity reference framework is discussed. These steps are part of a currently ongoing research project.
