The rising utilization of information and the frequent changes of systems necessitate continuous security engineering. Therefore, this work in progress presents the specificatio...

Due to Industry 4.0 developments, the demanded modularity of manufacturing systems generates additional manual efforts for security experts to guarantee a secure operation. The rising utilization of information and the frequent changes of system structures necessitate a continuous and automated security engineering, especially by application of the...

Manufacturing systems based on Industry 4.0 concepts provide a greater availability of data and have modular characteristics enabling frequent changes. This raises the need for new security engineering concepts that cover the increasing complexity and frequency of mandatory security risk assessments. In contrast, the current standardization landsca...

Integrity as one security objective is an important aspect for the adoption of the Asset Administration Shell (AAS) as a data exchange format and data source for data-driven services. Until now, the AAS offers an access control solution as a preventive integrity measure. Nevertheless, preventive methods lack detecting integrity violations due to ra...

Integrity as one property of trustworthiness is an important aspect for the adoption of the Asset Administration Shell (AAS) as a data exchange format and source for data driven services. Until now, the AAS offers an access control solution as a preventive integrity measure. Nevertheless, preventive methods lack in detecting integrity violations du...

The increasing availability of information, complexity of tasks, and demanded flexibility within the manufacturing automation domain enhances the necessity for new security engineering approaches. In contrast, the current standardisation landscape only offers static, manual, and resource-intensive procedures for the intrinsically mandatory risk ass...

The current static risk assessment processes and concepts do not match the increasing requirements with regard to flexibility within the industrial automation domain. The amount of manual tasks and needed efforts for risk assessments are too high in order to adequately cover the rising rate of system reconfigurations. Analysing the typical risk ass...

In the constant evolution of industrial systems, there is currently a strong trend towards Time-Sensitive Networking (TSN). This trend corresponds with the upcoming requirements of integration and flexibility in the Smart Factories and the fusion of Information Technology (IT) and Operational Technology (OT). However, industrial environments using...

Zusammenfassung Um die Sicherheit von industriellen Fertigungsanlagen von der Entwicklung über den Betrieb bis zur Entsorgung zu gewährleisten, werden bestimmte regulative und normative Anforderungen gestellt. Durch die Vernetzung und die weiteren Entwicklungen im Rahmen der Industrie 4.0 wird der manuelle Aufwand zum Erreichen dieser Sicherheit im...

The Asset Administration Shell (AAS) is a core element for Industrie 4.0. In addition, the security of industrial systems is a permanent topic that could be improved by the AAS and should have a high priority for future developments and implementations of the AAS. This paper evaluates the current threat landscape for Industrial Control Systems (ICS...

In order to ensure the safety and security of industrial systems with regard to all life cycle phases from development through operation to disposal, specific regulatory and normative requirements are imposed. Due to the digitalization, interconnection, and constantly increasing complexity of manufacturing systems in the context of Industrie 4.0, t...

Durch die Entwicklungen im Bereich der Industrie 4.0 und Arbeit 4.0 hin zu selbstorganisierten adaptiven Produktionssystemen entstehen neue Anforderungen an technische und soziale Systeme. Dazu gehören eine erhöhte Flexibilität, schnellere Entscheidungen und transparente Kommunikation, um den momentanen Marktdruck zu adressieren. Dadurch ist das Th...

Driven by rapid digitalisation, production systems are becoming more flexible and adaptable with the help of emerging concepts like the Internet of Things (IoT) and Industry 4.0. Often, these transformations are not fully implemented in Small and Medium-sized Enterprises (SMEs) due to the replacement cost of existing machines. This paper aims to de...

The advent of Industry 4.0 brings the Internet of Things (IoT) and Cyber-Physical Systems (CPSs) inside the factory premise and made the boundaries between the information and operational technologies (IT & OT) obsolete. This, in turn, introduces the problem of interoperability due to the integration of multiple industrial protocols and technologie...

Due to the dynamic nature of the Industrial Internet and Industry 4.0, future production systems will be reconfigured frequently and as a part of the engineering process, new system configurations will be deployed automatically. In order to keep pace with this development, it will be required to achieve the needed security level in an automated way...

Preface Our future is the world we are going to live in, attracting our fantasies, speculations, fears and hopes. We really would like to know something about it and want to be prepared. Therefore, we observe trends. An obvious trend is that our world gets more and more connected. Information is seamlessly following and doing this quickly. We learn...

Network connectivity in the current industrial sector is becoming more and more complex with the widespread adoption of diverse technologies to fulfill technical requirements. A complete overview of the network is not readily available and often not up-to-date due to the complex topology and heterogeneity in multi-vendor networks. Constraints like...

Due to the dynamic nature of the Industrie 4.0, future production systems will be reconfigured frequently and as a part of the engineering process, new system configurations will be deployed automatically. In order to keep pace with this development, it will be required to achieve the needed security levels in an automated way and to reduce the cur...

Die ganzheitliche Digitalisierung wirkt sich auch auf die Prozesse in der industriellen Produktionslandschaft aus. Die derzeitigen heterogenen Architekturen, bestehend aus drahtgebundenen und drahtlosen Technologien bzw. Protokollen, bringen neue Anforderungen an ein zukunftssicheres Netzwerkmanagement. Daher werden neue Ansätze zur Sicherstellung...

Today many hybrid (wired & wireless) industrial communication networks with a huge variety of heterogeneous technologies and protocols are present in the manufacturing and automation domain.
