【摘要】：針對證據(jù)數(shù)據(jù)完整性的問題,指出證據(jù)數(shù)據(jù)完整性評估的意義和重要性.通過考察信息系統(tǒng)在物理環(huán)境、網(wǎng)絡(luò)傳輸、主機(jī)與系統(tǒng)、應(yīng)用程序、管理和時間這六個方面對于證據(jù)數(shù)據(jù)完整性的影響和作用,提出了一種評估證據(jù)數(shù)據(jù)完整性的框架.運(yùn)用數(shù)據(jù)融合方法對評價結(jié)果進(jìn)行量化,通過分別對傳統(tǒng)終端取證方法和面向云的取證方法的實例進(jìn)行評估與量化,證實了該框架對證據(jù)數(shù)據(jù)完整性評估具有切實有效的指導(dǎo)作用及可操作性,結(jié)果表明使用傳統(tǒng)終端取證工具所獲取證據(jù)數(shù)據(jù)的不確定性在云環(huán)境下是傳統(tǒng)終端取證的5倍.
[Abstract]:Aiming at the problem of evidence data integrity, this paper points out the significance and importance of evidence data integrity evaluation. A framework for evaluating the integrity of evidence data is proposed by examining the influence and function of information system on the integrity of evidence data in physical environment, network transmission, host and system, application program, management and time. The evaluation results are quantified by using data fusion method, and the examples of traditional terminal forensics method and cloud-oriented forensics method are evaluated and quantified, respectively. It is proved that the framework is effective and effective in evaluating the integrity of evidence data. The results show that the uncertainty of evidence data obtained by using traditional terminal forensics tools is 5 times that of traditional terminal evidences in the cloud environment.
