In most cases in a safety analysis the in uences of security problems are omitted or even forgotten. Because more and more systems are accessible from outside the system via maintenance interfaces, this missing security analysis is becoming a problem. This is why we propose an approach on how to extend the safety analysis by security aspects. Such a more comprehensive analysis should lead to systems that react in less catastrophic ways to attacks.
