等のメールセキュリティ対策の国内での利用状況の実態を明らかにする．本稿では調査の結果概要を速報値的に報告する．調査の結果，2022 年 6 月現在，質問紙調査に回答した組織 344 件のうち約 64% が PPAP を利用していて，PPAP 利用組織の 88% が PPAP の有害性・無効性を認識しているにも関わらず利用を続けていることが明らかになった．また，PPAP

This study aims to clarify how, by whom, and why PPAP and other email security measures are chosen on the basis of a questionnaire survey and an email security analysis. This report provides a preliminary summary of the survey results. This survey revealed that approximately 64% of the 344 organizations that responded to the survey are still using PPAP (as of June 2022). Furthermore, 88% of the organizations that are using PPAP continue to use it even though they are aware of its harmfulness and ineffectiveness. It was also revealed that many organizations have e-mail operations that are vulnerable to attacks against PPAP.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"561","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2022論文集"}],"bibliographicPageStart":"554","bibliographicIssueDates":{"bibliographicIssueDate":"2022-10-17","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:23:00.344661+00:00","updated":"2025-01-19T13:15:28.063991+00:00","id":223131}
