However the installed software might include bugs or viruses. Then, it is necessary to protect the embedded system by secure OS. But the policy of the secure OS must set it strictly to control the installed software. Therefore, we propose the policy addition mechanism of secure OS for embedded system. The function of the proposed mechanism is an addition of the policy according to the system configuration. And it has the function to limit the policy that can be set to the software, because to limit the access of software according to the reliability of software. We implemented the proposed mechanism with SELinux, and verified the effectiveness. This mechanism achieves a secure software installation by adding the policy of secure OS.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"114","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"109","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-06","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21(2008-CSEC-040)","bibliographicVolumeNumber":"2008"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":44353,"updated":"2025-01-22T10:29:48.173209+00:00","links":{},"created":"2025-01-18T23:10:33.062617+00:00"}
