However, there is a possibility that attackers will delete logs to hide the evidence of their attacking and cheating. Moreover, various problems might cause the loss of logging information. To address these issues, we propose a system to prevent tampering and loss of logging information using a virtual machine monitor (VMM). In this system, logging information generated by the operating system (OS) and application program (AP) working on the target virtual machine (VM) is gathered by the VMM without any modification of the kernel source codes. The security of the logging information is ensured by its isolation from the VM. In addition, the isolation and multiple copying of logs can help in the detection of tampering. This paper describes the implementation and evaluation of the mechanism that protects logging information generated by the OS.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-07-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"28","bibliographicVolumeNumber":"2011-CSEC-54"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":75001,"created":"2025-01-18T23:32:18.343397+00:00"}
