    In Industry 4.0, Cyber-Physical Systems (CPS) are formed by components, which are interconnected with each other over the Internet of Things (IoT). The resulting capabilities of sensing and affecting the physical world offer a vast range of opportunities, yet, at the same time pose new security challenges. To address these challenges there are various IoT Frameworks, which offer solutions for managing and controlling IoT-components and their interactions. In this regard, providing security for an interaction usually requires performing additional security-related tasks (e.g. authorisation, encryption, etc.) to prevent possible security risks. Research currently focuses more on designing and developing these frameworks and does not satisfactorily provide methodologies for evaluating the resulting costs of providing security. In this paper we propose an initial approach for measuring the resulting costs of providing security for interacting IoT-components by using a Security Cost Modell ing Framework. Furthermore, we describe the necessary building blocks of the framework and provide an experimental design showing how it could be used to measure security costs at runtime.

    The onward development of information and communication technology has led to a new industrial revolution called Industry 4.0. This revolution involves Cyber-Physical Production Systems (CPPS), which consist of intelligent Cyber-Physical Systems that may be able to adapt themselves autonomously in a production environment. At the moment, machines in industrial environments are often not connected to the internet, which thus needs a point-to-point connection to access the device if necessary. Through Industry 4.0, these devices should enable remote access for smart maintenance through a connection to the outside world. However, this connection opens the gate for possible cyber-attacks and thus raises the question about providing security for these environments. Therefore, this paper used an adapted approach based on SixSigma to solve this security problem by investigating security standards. Security requirements were gathered and mapped to controls from well known security standards, formed into a catalog. This catalog includes assessment information to check how secure a solution for a use case is and also includes a link to an estimation method for implementation cost. Thus this paper’s outcome shows how to make Industry 4.0 use cases secure by fulfilling security standard controls and how to estimate the resulting implementation costs.
