Socio-Technical Security Modelling: Analysis of State-of-the-Art, Application, and Maturity in Critical Industrial Infrastructure Environments/Domains

This study explores the state-of-the-art, application, and maturity of socio-technical security models for industries and sectors dependent on CI and investigates the gap between academic research and industry practices concerning the modelling of both the social and technical aspects of security. Systematic study and critical analysis of literature show that a steady and growing on socio-technical security M&S approaches is emerging, possibly prompted by the growing recognition that digital systems and workplaces do not only comprise technologies, but also social (human) and sometimes physical elements.

Improving the Cybersecurity of Critical National Infrastructure using Modelling and Simulation

The UK Critical National Infrastructure is critically dependent on digital technologies that provide communications, monitoring, control, and decision-support functionalities. Digital technologies are progressively enhancing efficiency, reliability, and availability of infrastructure, and enabling new benefits not previously available. These benefits can introduce vulnerabilities through the connectivity enabled by the digital systems, thus, making it easier for would-be attackers, who frequently use socio-technical approaches, exploiting humans-in-the-loop to break in and sabotage an organization. Therefore, policies and strategies that minimize and manage risks must include an understanding of operator and corporate behaviors, as well as technical elements and the interfaces between them and humans. Better security via socio-technical security Modelling and Simulation can be achieved if backed by government effort, including appropriate policy interventions. Government, through its departments and agencies, can contribute by sign-posting and shaping the decision-making environment concerning cybersecurity M&S approaches and tools, showing how they can contribute to enhancing security in Modern Critical Infrastructure Systems.
