“…For this purpose, (Lohmüller et al, 2018) developed an approach how to calculate an optimal preventative trade-off between (partly) conflicting (multi-) concerns including safety, security as well as timing. A quick view on the approach delivers the following:…”

“…2. Identify failure modes and transfer it into a structured Safety Goal Hierarchy Model (SGHM) as described in (Lohmüller et al, 2018). The toplevel goal represents a safety goal since it is the main objective to obtain a system, which is acceptably safe.…”

Nowadays, modern cars can be configured by means of a wide range of software configuration options. In this context, we speak about Software Product Lines (SPLs). In almost every modern automotive vehicle safetycritical components like, e.g., an Adaptive Cruise Control (ACC) are installed. Some SPLs have different safety-critical requirements whereas other SPLs have similar requirements. This paper proposes an approach for the reduction of the complexity of SPLs without loss of safety (aspects) for all participants. For this purpose, a concept has been developed, which clusters products of SPLs with similar safety-critical requirements, i.e., the set of products of an SPLs, which must still be tested, can be reduced immensely. The paper also provides an application example how the reduced set can be used in order to perform a Safety, Security and Timing (SST) based trade-off analysis.

“…For instance, the reduced FM may be used subsequently in order to perform a trade-off analysis as suggested by (Lohmüller et al, 2018). In this context, there is a linking between the features of the reduced FM and the goals/SPOFs of the SGHM in order to eliminate non relevant goals/SPOFs from the SGHM.…”

“…In this regard, it is necessary to determine the best trade-off. This approach has already been presented in (Lohmüller et al, 2018). Moreover, modern vehicles can be configured by means of a construction kit.…”

“…Those analyses are already feasible, evaluated and offer metrics. Examples are analyses of Enterprise Architecture Management (EAM) [7] or automotive software engineering with safety and security concerns [9]. Our analyses are based on several of these, like change impact, failure impact or security analyses [10].…”

Internet of Things (IoT) is spreading increasingly in different areas of application. Accordingly, IoT also gets deployed in health care including ambient assisted living, telemedicine or medical smart homes. However, IoT also involves risks. Next to increased security issues also safety concerns are occurring. Deploying health care sensors and utilizing medical data causes a high need for IoT architectures free of vulnerabilities in order to identify weak points as early as possible. To address this, we are developing a safety and security analysis approach including a standardized meta model and an IoT safety and security framework comprising a customizable analysis language.
