Summary of Integrated Application of Functional Safety and Information Security in Industry
Wenze Xiong, Jianghong Jin · 2018
Functional safety and industrial control information security are two important aspects for guaranteeing the complete stability of a manufacturing process; they are inseparable from each other such as the control system, communication and software. Traditionally, independent functional safety standards and information security standards are applied in many high-risk industries. However, with increasing intelligent manufacturing, as well as continuous reformation of electronisation, digitisation and informatisation in the production process, functional safety and information security of complicated interconnected systems has become a challenge. On one hand, the connection between functional safety and information security is so close that it is difficult to clearly segment the two. On the other hand, new contradictions and conflicts may occur when safety and security problems are considered independently. Therefore, how to cooperatively and comprehensively consider functional safety and information security is a problem that remains to be solved. At present, there are some researches and theories in the published literature on the coordination or integration of functional safety and information security. This paper will synthesis these existing studies to carry out a detailed analysis on the difference between and relationship between functional safety and information security. The concept of integrated risk assessment and an integrated lifecycle model will also be proposed. Finally, a preliminary description and framework for how to achieve safety and security integration will be provided.
