The automotive industry is facing new challenges. Vehicles could be hit by Cyber-Attacks. Various new digital components of a vehicle are a new playground for hackers. Many manufactures have suffered such attacks, which had a direct effect of vehicles safety or data components. Based on this development Cyber- Security became more important for overall traffic safety. Cyber vulnerabilities and attacks impact the entire supply chain, jeopardizing trust and safety, and require all stakeholders to be proactive in analyzing risk, monitoring and responding effectively to cyber-attacks. The presentation introduces into the topic, shows attack vectors of hackers and shows how Volkswagen is responding to the challenges posed by the use of modern software-based technologies. Examples of real-life cybersecurity hacks provide the necessary practical relevance after the theoretical introduction. It is shown that any breakthrough in digital automotive (software) technology poses a security risk.
