DF-Salvia を開発してきた．DF-Salvia では，プロセスの挙動を監視し，プロセスがデータを書き出す際に，データの読み込み元のファイルに付加された保護ポリシに従って計算資源へのアクセス要求の実行可否を判定する．これにより，予め保護すべきデータが格納されるファイルにポリシを適用することで，正当なアクセス権限を持つユーザによるデータ漏洩を防止する．DF-Salvia のアクセス機構では，コンパイラにおいてプログラム解析したデータフロー情報に基づくことで，データの読み込み元のファイルを特定し，適用すべき保護ポリシを決定する．そこで，本稿では，DF-Salvia のアクセス制御のためのデータフロー情報のプログラム解析について述べる．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Recently, leak incidents of data have occurred frequently. In many cases, the factors of data leakage are as follows: taking data out illegally or unfairly, or misoperation by a user with authority to access them. We have been developing operating system DF-Salvia for the purpose of preventing data leakage which resulted from these factors. DF-Salvia monitors behavior of processes not to access computer resources which have a possibility of data leakage. When a process requests to access such resources, DF-Salvia allows the operation if it does not violate the data protection policy. The access control of DF-Salvia depends on data flow information which is obtained by program analysis. In this paper, method for analyzing the data flow information is described.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-03-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45","bibliographicVolumeNumber":"2011-DPS-146"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":73168,"links":{}}
