Connected and automated vehicles have been recently categorized as cybephysical entities, tightly related with a part of the Internet of Things (IoT) network. As a consequence the attack surface of a modern vehicle is increased, which added to the automation trend, makes cibersecurity risks a higher threat in the road. In this work a framework for automated vehicles is described, with the objective of validating security strategies when performing cooperative maneuvers. A review of the state of the art in automotive cibersecurity is presented, along its effect in automated vehicles, making special emphasis in inter-vehicle (V2V) communication and to the infrastructure (V2I). Moreover, two maneuvers are studied and a series of safety factors, taking into consideration the posible intervention of external malicious agents.
