SDNDL-CAO

SDNDL-CAO represents network assets in distributed healthcare environments using an ontology to enable structured information exchange for asset management and threat monitoring.

Key Features:

• Ontology-Based Representation: SDNDL-CAO encodes network assets (interfaces, devices, ports, and services) as subject–predicate–object triples for formal knowledge representation.
• Ontological Vocabularies: It leverages specific vocabularies grounded in ontological frameworks to standardize asset descriptors.
• FAIR Compliance: The ontology adheres to the FAIR principles (Findability, Accessibility, Interoperability, Reusability) for managing asset information in healthcare institutions.
• Federated Query Capability: Supports federated queries across multiple ontology systems to access and combine data from different sources such as hospitals.
• Threat Monitoring: Provides structured asset context to enable identification and monitoring of potential cybersecurity threats to personal medical information.
• Data Integration: Integrates data from multiple sources to support cross-institutional analysis and decision-making.

Scientific Applications:

• Network Asset Modeling: Provides structured models of interfaces, devices, ports, and services to support comprehensive asset inventories in healthcare networks.
• Federated Data Access: Enables querying and combining ontology data from multiple hospitals or institutions under a common governance body.
• Cybersecurity Detection and Response: Supports network administrators in monitoring, detecting, and responding to threats affecting medical information and network assets.
• Interoperability and Collaborative Analysis: Facilitates interoperability and collaborative analyses across healthcare institutions by standardizing vocabularies and asset descriptions.

Methodology:

The ontology model was designed to formalize essential concepts about network assets into subject–predicate–object triples and to support federated queries across ontology systems.
