Towards Combining STPA and Safety-Critical Runtime Monitoring

Abstract

The dependence on software in safety-critical system is increasingly growing and the reliability of the systems becomes more and more critical. Therefore, we need to adapt software engineering concepts like DevOps to also be able to react to changes faster. This process then also needs to be enriched by an alignment of an agile safety method with different phases of the DevOps cycle, where the contribution of my PhD is located. I plan to enhance the safety analysis method STPA with a concept to identify indicators for runtime monitoring and to provide valuable feedback to safety engineers about violations and trends of identified indicators, as well as suggesting new ones.
