Driven by the growing internet and remote connectivity of automobiles, combined with the emerging trend to automated driving, the importance of security for automotive systems is massively increasing. But although cyber security is a common part of daily work in the traditional IT domain, necessary know-how is not yet widely spread among automotive engineers. When considered superficially, this may not appear to be a problem as there are lots of common solutions from other domains, which might be appropriate. But actually there are substantial differences to be taken into account when trying to apply them to an automotive environment. Our paper will point out some basic knowledge about security in information systems, combined with a collection of current focal topics of work related to automotive security. Our contribution addresses the average automotive electronics or software engineer to give an overview on related current fields of activity and crucial points to think about when being confronted with security requirements for the first time.
