Privacy-centric infrastructures leveraging TEEs are therefore needed to ensure information-flow transparency and security without unconditionally trusting service providers. However, key prerequisites―capturing network configurations and performing fine-grained infrastructure-layer flow monitoring―remain insufficient. We propose a network monitoring platform that addresses this gap by extending a configuration ontology with a “Network Flow” data property and integrating topology data from SNMP measurements with administrator inputs such as NAT settings. Flow data are collected via per-node monitors using eBPF and Kubernetes CNI, aggregated by a collector, and exported in RDF. Experiments on test cases emulating real environments show that topology collection and ontology conversion remain practical even with more than 100 devices, and that flow description and monitoring using the extended ontology work as intended.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"69","bibliographicVolumeNumber":"2026-IOT-72"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2007446,"updated":"2026-02-16T07:52:19.264162+00:00","links":{}}
