However, the utilization of anonymized data for the purpose of utilizing big data to improve society is moving towards permission with amendments to the Personal Information Protection Law. We have created classifiers for harmless/malicious traffic using a data set of benign/malicious traffic collected by honeypots and performed partial anonymization according to the characteristics of each, such as replacing discrete values for features that have a large contribution to identification accuracy and privacy impact, while maintaining detection accuracy. In this study, we investigated the practicality of the proposed anonymous processing of traffic logs by applying partial anonymization to the features of a data set more similar to real-world communication, which has characteristics such as a larger range of communication time and volume than honeypots, and by evaluating the detection performance when the anonymization is applied. The practicality of the proposed anonymous processing of traffic logs was investigated by evaluating the detection performance when applied.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1013","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2024論文集"}],"bibliographicPageStart":"1006","bibliographicIssueDates":{"bibliographicIssueDate":"2024-10-15","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":240881,"updated":"2025-03-06T05:35:41.073452+00:00","links":{},"created":"2025-01-19T01:45:19.585473+00:00"}
