Embedded systems play an increasingly important role in today's automated and interconnected world. They are used for measurement and control in all types of equipment and systems. As linked modules, embedded systems are the key to revolutionizing energy supply, developing intelligent transport systems, connecting production systems and business IT systems and bringing improvement to many further areas. So embedded systems become increasingly networked, communication between these systems increases, giving rise to new challenges in the areas of security and availability. We must not only safeguard the complex interaction between state-of-the-art systems, but also ensure its safe and secure use.The complex interaction of modern technique has not only to be ensured, but it has also to be securely utilized.
