  This paper presents a systematic mapping study on the model-driven
engineering of safety and security concerns in systems. Integrated modeling and
development of both safety and security concerns is an emerging field of
research. Our mapping study provides an overview of the current
state-of-the-art in this field. Through a rigorous and systematic process, this
study carefully selected 95 publications out of 17,927 relevant papers
published between 1992 and 2018. This paper then proposes and answers several
relevant research questions about frequently used methods, development stages
where these concerns are typically investigated in, or application domains.
Additionally, we identify the community's preference for publication venues and
trends.
