“…A total of six reviews of joint safety and security analysis methods have been identified in the recent literature. Of those five, References [3][4][5][6]8] are narrative and only one [7] is systematic. Even though the total number of methods reviewed therein is 60, surprisingly, the intersection of the set of methods reviewed in Reference [7] and of the set of methods reviewed in all other reviews counts only seven elements.…”

“…Finally, Lyu et al [8] surveyed ten methods for safety and security analysis; these included five integrated approaches. The identified approaches were compared considering characteristics such as: quantitative/qualitative, model-based/system-based, top-down/bottom-up analysis, and hierarchical/dynamic analysis.…”

“…A systematic literature review was conducted by Lisova et al [7] that focused on already developed and evaluated methods. Lyu et al [8] provided a short survey, in which five integrated safety and security co-engineering methods were analyzed. Finally, Paul and Rioux [2] provided an extended bibliography of research papers on safety and cybersecurity co-engineering since the early 90s without, however, analyzing them.…”

Safeguarding both safety and cybersecurity is paramount to the smooth and trustworthy operation of contemporary cyber physical systems, many of which support critical functions and services. As safety and security have been known to be interdependent, they need to be jointly considered in such systems. As a result, various approaches have been proposed to address safety and cybersecurity co-engineering in cyber physical systems. This paper provides a comprehensive survey of safety and cybersecurity co-engineering methods, and discusses relevant open issues and research challenges. Despite the extent of the existing literature, several aspects of the subject still remain to be fully addressed.

Cyber‐physical systems (CPS) are applicable in emerging industries such as health, energy, autonomous vehicles, and Industrial Internet of Things (IIOT). In CPS the physical assets, that is, actuators and sensors, etc. communicate with each other over a messaging protocol. This communication process of CPS makes them vulnerable to cyber‐attacks which challenge the system safety, making security and safety two major concerns for CPS. Both safety and security risks are considered separately in literature. However, the International Society of Automation (ISA) focuses on the alignment of security and safety risks of CPS. Weak or no alignment in safety and security of a system may result in an inefficient or partially protected system which could end up in disasters. This pressed the need for an integrated safety‐security risk management process. For this purpose, we used a tetra packaging case study to (i) examine the vulnerabilities of CPS by running the risk management process, (ii) identify safety‐security requirements, and (iii) align retrieved safety‐security requirements with the relevant standards. The results show (i) safety hazards and security risks along with their severity and priority, (ii) mitigation guidelines are provided by consulting IEC 61508, and (iii) 15 safety‐security requirements are identified and are aligned with ISO9001 Packaging and labeling machine standard.
