Modern control systems are becoming complex and interconnected as they are increasingly integrating new information and communication technologies. Many industries like automobile, aeronautics and energy are facing great challenges as their systems are becoming less isolated and vulnerable to external malevolence. Indeed, cyber-attacks targeting industrial infrastructures can engender heavy impacts...
The need to address safety and security related aspects at an early stage of development of feedback control systems (FCS) has been identified as vital for the optimisation of the development process of military land systems. These systems often include network enabled capability (NEC) allowing the use of electronics architectures to integrate different sub-systems. However, this increased integration...
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...
The safety of vehicle electronic systems can be compromised by a malicious attack. In this paper, the authors describe their pragmatic approach to efficiently integrate the previously separate “security” aspects into the mature safety processes at an automotive Tier-1 supplier. Examples are given from the development of an electrical power steering controller.
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...
The increasing use of communications and computer-based technologies within vehicles and the highways network, creates both risks and opportunities. This paper examines the need to adopt a security-minded approach to the use of these new technologies in order to reduce the likelihood of them being maliciously exploited, and impacting on the safety or security: highway systems; vehicles, vehicles occupants;...
The safe and secure operation of critical national infrastructure is dependent on suitable responses to safety, security and operational priorities being integrated into Industrial Control Systems (ICS), at design stage and throughout the system life. This paper proposes a logical and structured approach to achieving this through successive consideration of the effect of decisions on pre-determined...
