“…The patent characterizes the inter-domain communication through an additional Meta Policy Decision Point (MPDP) to manage authentication and authorization processes between domains. The works [11] and [10], to the contrary, assign all the authentication process in the respective domains and concentrate all the authorization process in intermediaries PDP working like proxies.…”

“…This means that each entity should support at least two roles, one working as primary and other as secondary; and in this way, when control areas lack of enough connectivity, only authorized entities with determined roles could gain access to the affected area and take the control of this one. This propriety of DSD is widely described and implemented in [11,10].…”

“…But when different IT-OT domains have to coexist to collaborate each other, interconnection mechanisms have to be extensively considered as mentioned in our previous works [11,10].

Increasingly, the society is witnessing how today's industry is adapting the new technologies and communication protocols to offer more optimal and reliable services to end-users, with support for inter-domain communication belonging to diverse critical infrastructures. As a consequence of this technological revolution, interconnection mechanisms are required to offer transparency in the connections and protection in the different application domains, without this implying a significant degradation of the control requirements. Therefore, this book chapter presents a reference architecture for the new Industry 4.0 where the interconnection core is mainly concentrated in the Policy Decision Points (PDP), which can be deployed in high volume data processing and storage technologies such as cloud and fog servers. Each PDP authorizes actions in the field/plant according to a set of factors (entities, context and risks) computed through the existing access control measures, such as RBAC+ABAC+Risk-BAC (Role/Attribute/Risk-Based Access Control, respectively), to establish coordinated and constrained accesses in extreme situations. Part of these actions also includes proactive risk assessment measures to respond to anomalies or intrusive threats in time.

“…In [11], authors propose a dynamic authorization-based architecture based on Role Based Access Control, Policy Enforcement Points (PEPs) and Policy Decision Points (PDPs) to collect data streams from multiple sources connected to the Advanced Metering Infrastructure. Lastly, [12] presents a solution based on the use of PEPs and PDPs to interconnect large distributions with different vendor technologies.…”

In recent years, the Smart Grid has increasingly integrated cutting-edge technologies that generate several benefits for all the stakeholders involved, such as a more accurate billing system and enhanced Demand Response procedures. However, this modernization also brings with it diverse cyber security and privacy issues, which sets the necessity for developing a security platform specifically tailored to this scenario. In this paper, we present SealedGRID, which proposes a flexible architecture that provides security services at all levels by implementing Trusted Execution Environments on their devices, together with advanced authentication and authorization mechanisms, as well as privacy preserving techniques. These technologies are presented in depth and a final security analysis is conducted, which highlights the contributions of this project.

Since it was popularized in the 1990s, the adoption of lean production has been a primary driver for continuous improvement efforts worldwide. The next wave of industrial improvement is widely considered to be driven by industry 4.0 and digitalization. This has more recently led to the emerging concept of digital lean manufacturing. In this paper, we address a shortcoming in the extant literature, which presents an abundance of roadmaps for digitalization but very few addressing this in combination with lean. As such, we present a learning roadmap for digital lean manufacturing, with a core focus on cybersecurity. The roadmap has been developed and tested by combining theory with practical insights at the Norwegian Catapult Lean4zero Lab, Norway's first and only full-scale digital lean simulator.
