“…As it depends on the expert knowledge the reusability in repeated analysis is not applicable since the level of experiences might be different in different teams, potentially affecting results [4]. The approach presented by Silva et al (2013) [12] is also aligned with a standard from the railway domain, and in general depends on the expert knowledge. Given this the authors have not been completely convinced that the approach would be suitable for other domains without tailoring it to the specific needs.…”

“…The analysis proposed by [18] is based on FMEA that considers only single causes of an effect, which excludes multi-stage attacks consideration.

“…3) Silva and Lopes (2013) [12] present activities that have been performed in order to certify a safety-critical system in the railway domain and describe how security can be taken care of without endangering reliability or safety. In this work they use Failure Modes, Vulnerabilities and Effect Analysis (FMVEA) and fault tree analysis where for every safety failure event they derive possible security failure events.…”

Latest technological trends lead towards systems connected to public networks even in critical domains. Bringing together safety and security work is becoming imperative, as a connected safety-critical system is not safe if it is not secure. The main objective of this study is to investigate the current status of safety and security co-analysis in system engineering by conducting a Systematic Literature Review. The steps of the review are the following: the research questions identification; agreement upon a search string; applying the search string to chosen databases; a selection criterion formulation for the relevant publications filtering; selected papers categorization and analysis. We focused on the early system development stages and identified 33 relevant publications categorized as: combined safety and security approaches that consider the mutual influence of safety and security; safety informed security approaches that consider influence of safety on security; security informed safety approaches that consider influence of security on safety. The results showed that a number of identified approaches are driven by needs in fast developing application areas, e.g., automotive, while works focusing on combined analysis are mostly application area independent. Overall, the study shows that safety and security co-analysis is still a developing domain.

“…Hence, a reasonable compromise is to opt for a combination of quantitative and qualitative approaches for safety-security co-engineering. • The number of methods whose goal is to ensure both safety and security (32) is slightly larger than the number of those aiming to ensure safety (30), whilst only six methods have as their primary goal to ensure security. The appropriateness of each of these approaches depends largely on the system's safety/security criticality.…”

Cybersecurity and Safety Co-Engineering of Cyberphysical Systems—A Comprehensive Survey

2020

View full text Add to dashboard Cite

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.

“…During the design of interoperable medical devices, simultaneously considering security and safety is vitally important. Safety and security and their integrated modeling have been studied in various domains, such as industrial control, 22 railroad signaling systems, [23][24][25] and avionics. 26 The lessons learned in these domains can be applied when designing safety and security for interoperable medical Safe and secure interoperability needs to be considered early on in the development of medical devices.…”
