    The popularity of cloud based Infrastructure-as-a- Service (IaaS) solutions is becoming increasingly popular. However, since IaaS providers and customers interact in a flexible and scalable environment, security remains a serious concern. To handle such security issues, defining a set of security parameters in the service level agreements (SLA) between both, IaaS provider and customer, is of utmost importance. In this paper, the European Network and Information Security Agency (ENISA) guidelines are evaluated to extract a set of security parameters for IaaS. Furthermore, the level of applicability and implementation of this set is used to assess popular industrial and open-source IaaS cloud platforms, respectively VMware and OpenStack. Both platforms provide private clouds, used as backend infrastructures in Industry 4.0 application scenarios. The results serve as initial work to identify a security baseline and research needs for creating secure cloud environments for Industry 4.0.

    The growing demand for interoperability between system components within a connected car has led to new security challenges in automotive development. The existing components, based on established technology, are often being combined to form such a connected car. For such established technologies, individual, often sector specific threat and vulnerability catalogs exist. The aim of this paper is to identify blocks of established technologies in a connected car and to consolidate the corresponding threat and vulnerability catalogs relevant for the individual constituent components. These findings are used to estimate the impact on specific system components and subsystems to identify the most crucial components and threats.

    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.
