Vehicles are becoming every generation more smart and ICT oriented: modern cars are characterized by dozens of different Electronic Control Units (ECUs), each one hosting one or more applications devoted to monitor and manage every single aspect of the vehicle itself. Advanced Driving Assistance Systems, nowadays becoming a standard, are going further, moving the control of safety critical systems, like braking and steering, to computers, algorithms and software. Previous researches demonstrated that many security flaws do exist in commercially available vehicles due to the massive presence of software. Network protocols designed without taking into proper account security design principles and application bugs have been exploited by researchers to remotely take over the control of different vehicular systems, without the possibility for the actual drivers to react.
