Is there any specific term or common definition that can be used to describe the concept of 'Safety Critical'?

The closest I can achieve is to consider the compound of Safety Critical with additional terms such as 'Function', 'Task', 'Feature', etc. where the existence of such provides controls to protect against an immediate realisation of a hazardous state, and the failure of such would result in that hazardous state.

Dear Members,

The SCSC are invited to participate in an online survey that forms part of an MSc research project (Safety Critical Systems Engineering – University of York) titled;

‘Integrated Safety & Security Causality Modelling & Analysis: Current Challenges & Potential Solutions within the UK’s Critical National Infrastructure’

“If it’s not secure, it’s not safe”– this assertion is the foundational principle behind the research project.

In recent years, a paradigm shift has occurred within the safety engineering discipline as security has been recognised as a fundamental and integral component of safety; security has the potential to protect the safety attributes of a system and compromise the safety attributes of a system, both directly and indirectly.

The question of whether a system can be considered safe in the absence of security considerations is at the centre of this paradigm shift. Will a safety critical system perform the required safety functions to the required (or claimed) performance level where security has not been considered? Is the causal chain of hazards limited exclusively to accidental failures (e.g. random hardware, systematic and common cause failures)? Is the requirement to consider malicious acts or negligent actions unnecessary as they cannot cause hazards that have not already been identified or contribute towards those that have? Can this be substantiated in the absence of evidence? What processes and evidence artefacts are necessary to substantiate that the hazard analysis for the system is suitable and sufficient?

Integrated safety & security causality modelling and analysis is an approach to hazard analysis that takes into consideration both safety and security contributions to system safety.

The purpose of this survey is to gather the experiences and observations of four principal stakeholder perspectives relating to the subject of 'integrated safety and security causality modelling and analysis' within the UK’s Critical National Infrastructure (CNI). 

The objective of the research project is to understand the current challenges experienced (primary data gathered through the survey) for the purposes of identifying potential [focussed] solutions for further development (this may include for example an extension/ adaption of a commonly used existing safety causality modelling and analysis technique to account for security considerations). 

The survey consists of twenty logically presented questions that shall take you approximately 15 minutes to complete. Further information regarding the survey can be found within the Participant Information Sheet.

Your participation would be very much appreciated as it represents valuable real-world insight into a very significant and emerging field of safety engineering.

Please feel free to share the invitation to other relevant safety and/or security practitioners working within the UK’s Critical National Infrastructure for their valued participation.

Thank you for your participation and support.
