a countermeasure against network attacks, firewall systems integrating signature-based IPS (Intrusion Prevention Systems) are widely used. However, as rule sets expand to address the increasingly sophisticated attacks, the processing time for inspection increases, leading to a decline in overall system performance. In this paper, we propose a method for virtually deploying two IPS instances on a single host using Open vSwitch (OVS). We compare the proposed virtualized environment with a conventional single-IPS configuration on the same host in terms of packet processing latency and throughput. In addition, we conduct evaluation experiments under DoS attack scenarios to assess the impact of host-level virtualization on IPS performance.","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":"27","bibliographicVolumeNumber":"2026-IOT-72"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2007404,"updated":"2026-02-16T07:50:36.787991+00:00","links":{}}
