Cybersecurity for Industry 4.0 in the current literature: A reference framework

The cybersecurity issues represent a complex challenge for all companies committing to Industry 4.0 paradigm. On the other hand, the characterization of cybersecurity concept within Industry 4.0 contexts proved to be an emerging and relevant topic in the recent literature. The paper proposes to analyse, through a systematic literature review approach, the way in which the existing state of art deals with the cybersecurity issues in Industry 4.0 contexts. In particular, the focus will be on the investigation of the main elements associated with cybersecurity theme (i.e. asset involved into cyber-attacks, system vulnerabilities, cyber threats, risks and countermeasures) within those industrial contexts where physical systems (machines, shop floors, plants) are connected each other via the Internet. Four areas of analysis are defined: definitions of cybersecurity and Industry 4.0 concepts, the industrial focus of the analysed studies, the cybersecurity characterization and the management attempts of cybersecurity issues. Through the literature review analysis, a framework of the main features characterizing each area is discussed, providing interesting evidences for future research and applications

Multi-core devices for safety-critical systems: a survey

Multi-core devices are envisioned to support the development of next-generation safety-critical systems, enabling the on-chip integration of functions of different criticality. This integration provides multiple system-level potential benefits such as cost, size, power, and weight reduction. However, safety certification becomes a challenge and several fundamental safety technical requirements must be addressed, such as temporal and spatial independence, reliability, and diagnostic coverage. This survey provides a categorization and overview at different device abstraction levels (nanoscale, component, and device) of selected key research contributions that support the compliance with these fundamental safety requirements.This work has been partially supported by the Spanish Ministry of Economy and Competitiveness under grant TIN2015-65316-P, Basque Government under grant KK-2019-00035 and the HiPEAC Network of Excellence.

Sistematização dos requisitos gerais para o desenvolvimento de software na indústria 4.0

The identification and implementation of technologies and innovations, through the development of business strategies, are factors that contribute to organizational success. In this context, industry 4.0 can contribute to the development of industries that seek technological and innovative differentials. The objective of this research is to develop a system for software development in industry 4.0. Because they are current topics and linked to technology and innovation, they are still underdeveloped in academic studies. Through a bibliographic review, using bibliometrics and content analysis techniques, the general requirements for software development in industry 4.0 were identified, and for each requirement, what are the challenges, risks, gaps, advantages and trends. The systematic is analyzed by academic experts, being considered as theoretical with the incorporations of the practice. The AHP method was used to prioritize the requirements, resulting in the adjusted systematic, having as elements and relative score of the specialists: analysis of opportunities 34.98%, operational efficiency 2.0 19.41%, optimization of the business model 15.57%, information technology 20.26%, IT integration 12.29%, IT security management 7.97%, new interfaces and data 17.93%, data analysis and management 6.90%, new intellectual property management 6.69%, cloud-based applications 4.34%, integrated and intelligent management 10.75%, intelligent supply chain 3.85%, lifecycle management 3.81%, intelligent logistics 3.09%, change and learning 16.08%, corporate business 9.33%, organizational learning 6.75%. Among the criteria, the requirement that got the most weight was the analysis of opportunities and among the sub-criteria the ones with the highest weight were: operational efficiency, optimization of the business model and IT integration. Finally, an analysis by specialists from companies that develop software is applied to understand how the requirements are used in these companies, reaching the final system. The research through the AHP, showed the importance of analyzing opportunities and operational efficiency in organizations, justifying that companies are concerned with identifying business opportunities and managing processes efficiently. These results also showed the stage of preparing the system as the most relevant. The interviews demonstrated the concern with cybersecurity and IT integration tools, but the gap was shown in relation to the development of integrated and intelligent management, with emphasis on intelligent logistics.Agência 1A identificação e implementação das tecnologias e inovações, por meio do desenvolvimento de estratégias empresariais, são fatores que contribuem para o sucesso organizacional. Neste contexto, a indústria 4.0 pode contribuir para o desenvolvimento das indústrias que buscam pelo diferencial tecnológico e inovador. O objetivo desta pesquisa é desenvolver uma sistemática para o desenvolvimento de software na indústria 4.0. Por serem temas atuais e ligados à tecnologia e inovação, ainda são pouco desenvolvidos nos estudos acadêmicos. Por meio de uma revisão bibliográfica, utilizando técnicas de bibliometria e análise de conteúdo, identificaram-se os requisitos gerais do desenvolvimento de software na indústria 4.0, e para cada requisito, quais são os desafios, riscos, lacunas, vantagens e tendências. A sistemática passa por análises de especialistas acadêmicos, sendo considerada como teórica com as incorporações da prática. O método AHP foi utilizado para priorizar os requisitos, resultando na sistemática ajustada, tendo como elementos e pontuação relativa dos especialistas: análise de oportunidades 34,98%, eficiência operacional 2.0 19,41%, otimização do modelo de negócios 15,57%, tecnologia da informação 20,26%, integração de TI 12,29%, gerenciamento de segurança de TI 7,97%, novas interfaces e dados 17,93%, análise e gerenciamento de dados 6,90%, novo gerenciamento de propriedade intelectual 6,69%, aplicações baseadas em nuvem 4,34%, gestão integrada e inteligente 10,75%, cadeia de suprimentos inteligente 3,85%, gerenciamento do ciclo de vida 3,81%, logística inteligente 3,09%, mudança e aprendizagem 16,08%, negócio corporativo 9,33%, aprendizagem organizacional 6,75%. Entre os critérios, o requisito que obtive maior peso foi a análise de oportunidades e entre os subcritérios os de maior peso foram: eficiência operacional, otimização do modelo de negócios e integração de TI. Por fim, é aplicada uma análise de especialistas de empresas que desenvolvem software para entender como os requisitos são utilizados nessas empresas, chegando à sistemática final. A pesquisa por meio do AHP, mostrou a importância da análise de oportunidades e da eficiência operacional nas organizações, justificando que as empresas se preocupam em identificar as oportunidades de negócios e gerenciar os processos de forma eficiente. Esses resultados também mostraram a etapa de preparação da sistemática como a mais relevante. As entrevistas demonstraram a preocupação com a cybersegurança e as ferramentas de integração de TI, porém mostrou-se o gap em relação ao desenvolvimento da gestão integrada e inteligente, com destaque para a logística inteligente
