System safety and cyber security have a great effect on system reliability which is the foundation of keeping system running-normally. Although safety and security controls can reinforce each other mutually, contradictions between them also exist, such as resource competition that may cause serious damage. This paper puts forward a risk-based task scheduling approach for the integrated control of...
The close connection between safety and security has led to a growing interest in a combined handling of these two areas of research. The paper presents a roadmap for realizing such a combined handling. The conditions enabling a combined safety and security analysis are identified and used as starting point of the elaboration. Utilizing these properties, a theoretical framework unifying key aspects...
Industrial Control Systems (ICS) are now routinely connected to other networks to optimise business efficiency. Designs for safety and security risk treatment measures may conflict and cannot be designed in isolation yet we find there are still problems in combining them. If a CEO were to ask his safety engineer and his security engineer of a complex, networked, software-intensive system to produce...
