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