Knowledge representation in the Materials Science and Engineering (MSE) domain is a vast multi-faceted challenge: Overlap, ambiguity, inconsistency terminology are common. Invariant (consistent) variant (context-specific) knowledge difficult to align cross-domain. Generic top-level semantic often too abstract, while MSE specific. In this paper, an approach how maintain comprehensive MSE-centric composing mid-level ontology–the Platform MaterialDigital Core Ontology (PMDco)–via...
The digitalization of materials science and engineering (MSE) is currently leading to remarkable advancements in research, design, optimization, fueled by computer‐driven simulations, artificial intelligence, machine learning. While these developments promise accelerate innovation, challenges quality assurance, data interoperability, management have be addressed. In response, the adoption semantic web technologies has emerged as a powerful solution MSE. Ontologies provide structured...
<ns3:p>Ongoing digitalization and data-driven developments in materials science engineering (MSE) emphasize the growing importance of reusing research data enabling machine accessibility, which requires robust management consistent semantic representation. Ontologies have emerged as powerful tools for establishing interoperable reusable structures from inconsistent structures. Despite advancements representation specific applications, integrating application ontologies with primary...
This article describes advancements in the ongoing digital transformation materials science and engineering. It is driven by domain‐specific successes development of specialized data spaces. There an evident increasing need for standardization across various subdomains to support exchange entities. The MaterialDigital Initiative, funded German Federal Ministry Education Research, takes on a key role this context, fostering collaborative efforts establish unified space. implementation...
Asset information obtained via infrastructure analysis is essential for developing and establishing risk management. However, about assets acquired by existing processes often incomplete or lacking in detail, especially concerning their interconnected topology. In this paper, we present the Interconnected-asset Ontology, IO, as a step towards standardized representation of detailed asset information. The utilization an ontology machine-readable supports automation management standardization...
Abstract This manuscript describes the accelerated development of an ontology for microscopy in materials science and engineering, leveraging natural language processing (NLP) techniques. Drawing from a comprehensive corpus comprising over 14 k contributions to Microscopy Microanalysis conference series, we employed two neural network-based algorithms NLP. The goal was semiautomatically create Ontology (MO) that encapsulates interconnects terminology most frequently used by community. MO,...
Securing a safety-critical system is challenging task, because safety requirements have to be considered alongside security controls. We report on our experience develop architecture for railway signalling systems starting from the bare that requires protection. use threat-based approach determine risk acceptance criteria and derive requirements. discuss executed process make suggestions improvements. Based requirements, we architecture. The based hardware platform provides resources...
Multi-chassis (MC) endpoints and link aggregation groups (LAG) are common configurations in production networks today. Security automation processes that rely on correct topological data require a machine-process able representation of corresponding network topologies. Unfortunately, MC-LAG setups can be interpreted more than one way regarding the layout, which complicates process significantly. In this paper we present an extension to Interconnected-asset topology (IO) provides detailed...
Security testing of IT-infrastructure in a production environment can have negative impact on business processes supported by IT-assets. A test bed be used to provide an alternate order mitigate this impact. Unfortunately, for small and medium enterprises, maintaining physical its consistency with the is cost-intensive task. In paper, we present Infrastructure Replication Process (IRP) corresponding Topology Editor, cost-efficient method that makes security enterprises more feasible. We...
Ethernet-based networks for Industrial Control Systems (ICS) rely on redundant links to mitigate failures, increase availability, but also masking failures and complicating assessment of redundancy remaining. We use the Interconnected-asset Ontology represent topologies from automated snapshots without need changes infrastructure or fundamental operation ICS network. The presented approach prototype provides assessments seamlessly integrated in a state-of-the-art industrial control system.
The deployment of new security technologies in existing network topologies requires exhaustive testing before usage to avoid down time the production systems. Nowadays, required is many cases omitted due complexity creating test and experimental set ups. VISA (Virtual IT Security Architectures) project [1], funded by German Federal Ministry Research, aims provide a simulation environment for semi-automated experiments based on system models. Building Virtualised Appliances (VSA) enterprise...
In critical infrastructures such as railway systems, the continuous and resilient availability of safety functions residing on actuator sensor components must be ensured. Since these are also more connected using Internet Protocol (IP), they additionally require security to provide protection against attackers. Moreover, infrastructure is highly distributed, with its at track side easily accessible Thus, a proofing that the safety-critical systems not manipulated is required, too. The...
