    Secure Granular Interoperability with OPC UA
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft (Workshop-Beiträge), 2019) Watson, Venesa; Sassmannshausen, Jochen; Waedt, Karl
    Open Platform Communications Unified Architecture (OPC UA) is the communication standard earmarked for future industrial automation, particularly for the Industry 4.0 (I4.0) infrastructure where it provides the key services for interoperability and built-in communication security. OPC UA defines several models for these services and has already been deployed by industrial partners in their efforts to achieve I4.0 market readiness and to provide more robust systems. Of particular interest is the security services offered by OPC UA, as they are expected to strengthen the security posture of industrial automation systems, which have so far suffered a number of sophisticated cyber-attacks. In general, cyber-attacks are more severe based on the level of access acquired by the attacker, for example, an attacker with unrestricted administrative level access can issue more powerful commands. It is safe to say then that a more stringent access control security concept can offer systems greater protection from unauthorized access. Several access control models exist, which are categorized under two headings discretionary (data owners/users set the access control rules) and non-discretionary (security administrators control the access granted to users). Here, a non-discretionary access control model, namely the attributebased access control (ABAC) model is compared to the role-based access control (also nondiscretionary) typically assumed with OPC UA, to ascertain how a more granular security structure with ABAC could provide additional security advantages for industry.

    Semantics for I4.0 Smart Manufacturing
    (INFORMATIK 2020, 2021) deMeer, Jan
    In the realm of ‚Smart Manufacturing' the ‚SemNorm' Project addresses the question of how to at derive an executable Digital Twin (DT) from standards. A Digital Twin is a virtual representation that embodies an asset of any type {[}IOSB18{]}. In that sense a DT is compared to the Asset Administration Shell (AAS). Smart Manufacturing is a real thing of a factory represented by its structure and behavior of inter-connected things that generate real-time data {[}IOSB18{]}. By combining Smart Manufacturing processes with a Digital Twin it is intended to validate operations of a production systems in real-time. In general the properties of inter-operating things respectively systems, and especially the properties of energy transportation between systems are considered to be the ‚Prove of Concepts' (PoC) of semantics. When The Information Technology (IT) that processes data and up to some extend information, is compared to the technology that enables communication among things or objects then the technology is called Operation Technology (OT). Whereas the semantics of IT is straight-forward, namely the interpretation of data objects in different contexts of a sending and a receiving environment, the semantics of OT is achieved on two levels. The the first (informal) level explains semantics as a narrative of how things are processed in a smart manufacturing plant, whereas the second (formal) level defines semantics more formally, i.e. by means of graph manipulations. Graph Manipulations represent sequences of events that are related to the narrative of talking about inter-operations among things. At same time a graph is a computational representation in terms of sequences of events (so-called runs) that are executable by appropriate tools from the shelve. Thus graph computations and told narratives are said to be ‚similar', respectively ‚comparable' since they are related to each other by a morphism i.e. the formal relationship between artifacts of graphs, artifacts from the standard ontology and artifacts of the technical asset domain. The OT narration validated by a graph semantics analysis is finally to be transformed into a standard's document which is then called to be a Semantic Standard. This process is a backward transformation of interoperation properties from a semantic representation into an English text that describes the requirements of these properties. In a forward transformation it is started with the textual standards together with the derived guidelines to transform the standard into a semantic representation respectively a Digital Twin.
